    ARGUED SEPTEMBER 21, 2004—DECIDED MARCH 18, 2005
    ____________
    Before EASTERBROOK, RIPPLE and WILLIAMS, Circuit Judges.
    RIPPLE, Circuit Judge. Early in the morning of May 5, 2001,
    Marion County Sheriff’s Deputy Ronald Shelnutt shot and
    killed John Patrick Leaf. Members of Mr. Leaf’s family (“the
    Leafs”) brought this action pursuant to 
    42 U.S.C. § 1983
     and
    Indiana state law for alleged constitutional violations and
    other torts arising from this tragic event. The district court
    granted in part and denied in part Deputy Shelnutt’s motion
    for summary judgment. For the reasons set forth in the

    following opinion, we now reverse the district court and
    remand for further proceedings.

    BACKGROUND
    A. Facts
    On the night of May 4, 2001, John Patrick Leaf patronized
    a bar in Indianapolis. When he left the bar, he turned over
    his keys to a friend and took a taxicab to his home at 8863
    Lake Nora West Drive, Apartment B, in the Lake Nora Arms
    Apartments. When he arrived, he forced entry into his own
    apartment.
    Around 1 a.m. on May 5, Dustin Kersey, Ryan Murphy and
    Vito Sanders, residents of the Lake Nora Arms Apartments,
    heard glass breaking in the direction of Mr. Leaf’s apart-
    ment. The residents called out to see what was happening,
    and the sounds of glass breaking stopped for a few minutes
    and then resumed. When the sounds of glass breaking be-
    gan again, the residents went to investigate. Kersey, Murphy
    and Sanders arrived at the patio entrance to Mr. Leaf’s apart-
    ment and saw a man trying to gain entrance to the apart-
    ment. Mr. Leaf introduced himself to the residents and
    explained that he lived in the apartment but did not have his
    keys. The men had not met Mr. Leaf prior to that night.
    They talked with Mr. Leaf briefly and then left. Murphy
    later returned to Mr. Leaf’s apartment to make note of the
    address and then called 911 from his own apartment at 1:10
    a.m., but hung up before his call was answered.
    That night, Deputy Andrew Jacobs was working for the
    Meridian Hills Police Department. Deputy Jacobs some-
    times served as a special deputy for the Marion County
    Sheriff’s Department and volunteered to respond to the in-
    No. 04-1318                                                  3
    complete 911 call on behalf of that department. Deputy
    Jacobs responded to the call at Murphy’s apartment; he
    arrived at around 1:22 a.m. Murphy told Deputy Jacobs that
    the man he had seen breaking a window had claimed to be
    the occupant of the apartment and had claimed that he did
    not have his keys. According to Deputy Jacobs, Murphy also
    said that the man at the apartment had been belligerent.
    Deputy Jacobs did not know that the residents had shaken
    hands with Mr. Leaf or that Mr. Leaf had introduced himself.
    For two or three minutes, Deputy Jacobs spoke with
    Murphy and the other residents who had seen Mr. Leaf.
    Deputy Jacobs then drove to Mr. Leaf’s apartment. There,
    he observed the apartment from outside the fence that en-
    closed a patio at the back of Mr. Leaf’s apartment. Deputy
    Jacobs noticed that the patio door was open and that a win-
    dow at the rear of the apartment was broken. He then walked
    through the fence gate and into the patio area, where he
    could see that the vertical blinds that hung at the apartment’s
    patio doorway were moving. The blinds, hung inside the
    apartment, were blowing outside. Deputy Jacobs pushed the
    blinds aside to look into the apartment. He saw an item,
    later identified as an ice chest, pushed up against the front
    door. Deputy Jacobs testified that burglars sometimes will
    obstruct all entries to a home except those through which
    they enter and exit.
    At that point, Deputy Jacobs called for backup, and
    Deputy Shelnutt responded. Deputy Jacobs stated in the call
    that there was an open patio door and a broken window,
    but did not specifically say that he believed there had been
    a burglary. He continued to observe the apartment until 1:30
    a.m., when Deputy Shelnutt arrived. Deputy Jacobs testified
    that he told Deputy Shelnutt about the substance of his
    conversation with the residents—specifically, that
    4                                                 No. 04-1318
    the residents had spoken with the man seen entering the
    apartment and that they did not know whether that man
    lived in the apartment.
    About one minute after Deputy Shelnutt arrived, the
    officers entered the apartment. The deputies did not radio
    to say they would be entering the apartment. In fact, once
    Deputy Shelnutt responded to Jacobs’ call, neither Deputy
    Jacobs nor Deputy Shelnutt made any radio communica-
    tions with the police department until they radioed to report
    that there had been a shooting.
    The officers entered the apartment with guns drawn,
    using the tactical lights attached to the barrels of their guns
    to illuminate the dark apartment. Neither officer knocked
    before entering the apartment. However, Deputy Jacobs
    testified in his deposition that he announced from outside
    the apartment, “This is the Marion County Sheriff. Come
    out now. Show yourself. This is the Marion County Sheriff.
    Come out now. Show yourself.” R.147, Ex.7 at 155. Deputy
    Shelnutt made no announcements. Deputy Jacobs testified
    that he “could” have said, “Come out and make yourself
    known,” but that he did not “recall” making such an an-
    nouncement. R.147, Ex.7 at 155. Deputy Jacobs also said that
    he did not announce that the officers would enter the
    apartment. Deputy Shelnutt, however, testified at his dep-
    osition that he recalled Deputy Jacobs announcing, “We will
    be searching the apartment.” R.147, Ex.13 at 120.
    Once the officers entered the apartment, Deputy Shelnutt
    noticed light coming from the front door, and concluded
    that, before the front door was secured shut with the ice
    chest, the front door had been kicked in and the door frame
    broken. The officers searched the apartment, including the
    bedroom, where they found Mr. Leaf lying naked and un-
    covered on his bed, face up, with his eyes closed. Mr. Leaf
    was breathing deeply. After finding Mr. Leaf on the bed but
    No. 04-1318                                                  5
    before waking him, Deputy Shelnutt conducted a search
    lasting approximately three minutes, in order to determine
    whether anyone was hiding; Deputy Jacobs remained in the
    bedroom. Deputy Shelnutt checked the kitchen, two hall
    closets, a bedroom closet and a bathroom. In the bedroom,
    Deputy Shelnutt then approached the bed with his gun
    drawn and the tactical lights illuminated, in order to awaken
    Mr. Leaf. It is disputed whether Deputy Shelnutt actually
    touched Mr. Leaf. Deputy Shelnutt did not “recall” touching
    Mr. Leaf’s shoulder. R.147, Ex.13 at 160. Deputy Jacobs, on
    the other hand, testified in his deposition that he saw
    Deputy Shelnutt nudge Mr. Leaf. R.147, Ex.7 at 35, 177.
    At this point, the officers claim, Mr. Leaf jumped up from
    the bed and lunged at Deputy Shelnutt, wielding a 15-inch
    bowie knife. Deputy Jacobs did not remember which hand
    Mr. Leaf used to wield the knife, but recalled that Mr. Leaf
    waved the knife in a “figure eight” motion. R.147, Ex.7 at 178.
    The officers told Mr. Leaf to drop the knife and shouted,
    “Sheriff’s Department” or “Police.” R.147, Ex.7 at 188; R.147,
    Ex.13 at 177, 178. When Mr. Leaf continued to advance
    toward Deputy Shelnutt with the knife, Deputy Shelnutt
    retreated a step or two into the bathroom. Deputy Shelnutt
    then fired four shots at Mr. Leaf, hitting him three times.
    Mr. Leaf died from the gunshot wounds.
    B. District Court Proceedings
    On February 19, 2002, members of Mr. Leaf’s family ini-
    tiated this action in Indiana state court pursuant to 
    42 U.S.C. § 1983
     and Indiana state law. The Leafs named as defendants
    Deputies Jacobs and Shelnutt in their individual capacities,
    as well as Marion County Sheriff Jack Cottey and Meridian
    Hills Town President Ed Perry in their official capacities.
    The Leafs alleged that Deputy Shelnutt and Deputy Jacobs
    6                                                     No. 04-1318
    violated Mr. Leaf’s rights under the Fourth and Fourteenth
    Amendments to the Constitution. In particular, the Leafs
    claimed that the officers had unlawfully searched Mr. Leaf’s
    apartment, that they had unlawfully seized him and that
    both officers had deprived Mr. Leaf of life, liberty or prop-
    erty without due process of law. The Leafs further asserted
    that Deputy Shelnutt had used excessive force against
    Mr. Leaf. They also advanced § 1983 claims for failure to in-
    tervene on Mr. Leaf’s behalf against both Deputy Shelnutt
    1
    and Deputy Jacobs. On March 20, 2002, the defendants
    removed the action to the United States District Court for
    the Southern District of Indiana.
    In a motion filed July 21, 2003, the Leafs sought partial
    summary judgment from the district court. They contended
    that the officers had unlawfully seized Mr. Leaf. The officers
    responded that they did not unlawfully seize Mr. Leaf and
    asserted qualified immunity as a defense. In an order issued
    October 14, 2003, the district court denied summary judg-
    ment on the question of illegal seizure. The court concluded
    that Mr. Leaf was seized while lying in his bed. Noting that
    there was a “factual dispute about whether Shelnutt touched
    or nudged Leaf . . . in an effort to wake him,” R.172 at 4, the
    district court did not determine whether Deputy Shelnutt
    touched Mr. Leaf. The court found that the fact that Mr. Leaf
    1
    The Leafs also alleged claims of deliberate indifference and un-
    constitutional policy, custom or practice against Sheriff Cottey
    and Town President Perry. The Leafs asserted additional claims
    for damages under Indiana law against Deputies Shelnutt and
    Jacobs for trespass, false arrest, assault and battery and negligent
    failure to follow Indiana law and the policies and procedures of
    the Marion County Sheriff’s Department, and against Cottey and
    Perry for negligent hiring, supervision and retention of Deputies
    Shelnutt and Jacobs.
    No. 04-1318                                                    7
    “did not flee from the officers’ show of authority (or phy-
    sical touching, if one occurred),” R.172 at 7, demonstrated
    that a seizure had occurred. However, the court denied
    summary judgment on the grounds that a trier of fact could
    find that the seizure was “not unreasonable under the cir-
    cumstances known to the officers at the time,” and that a
    trier of fact could find that “the scope and method of the
    seizure was reasonable under the circumstances.” R.172 at
    11-12. The district court did not address the officers’ asser-
    tion of qualified immunity. In November 2003, the Leafs
    reached a settlement with Deputy Jacobs, and he was
    released from the litigation.
    On January 24, 2004, the district court granted in part and
    denied in part a motion for summary judgment made by
    Sheriff Cottey and Deputy Shelnutt. Because Deputy Shelnutt
    is the sole appellant in this appeal, we shall discuss the
    district court’s order only as it applies to him.
    The district court denied summary judgment on what it
    called “UNLAWFUL ENTRY AND SEARCH.” R.219 at 12.
    The court determined that exigent circumstances justified
    the officers’ warrantless entry into Mr. Leaf’s apartment.
    However, the court found that the way in which the officers
    entered may have violated the Constitution. The court ex-
    plained that the Fourth Amendment requires law enforce-
    ment personnel to knock on the door of a private dwelling
    and to announce both their identity and their purpose
    before entering. R.219 at 12-14. The district court found that
    Deputies Shelnutt and Jacobs had announced their presence,
    but the court found that a question of fact existed as to whether
    Deputy Jacobs had announced, “We will be searching the
    apartment,” prior to entering. R.219 at 14. The court also
    found that a question of fact existed regarding whether, once
    inside the apartment, Deputy Shelnutt behaved in an ob-
    jectively unreasonable manner by searching the apartment
    8                                                     No. 04-1318
    and not announcing his identity. R.219 at 16-17. Therefore,
    the district court denied Deputy Shelnutt’s motion for
    summary judgment on the illegal search claims.
    The district court also denied summary judgment on the
    excessive force claim because it could not determine as a
    matter of law that Mr. Leaf posed a threat of death or ser-
    ious bodily injury to Deputy Shelnutt. Because the district
    court found fact issues precluding summary judgment on
    the claims for illegal search, entry and seizure, it denied
    Deputy Shelnutt summary judgment on the failure to in-
    tervene claim. The district court granted Deputy Shelnutt’s
    motion for summary judgment on the Leafs’ due process
    claim.
    The district court then turned to Deputy Shelnutt’s as-
    sertion of qualified immunity as a defense to “the claims for
    unlawful entry, search and seizure, and excessive force.”
    R.219 at 25. The district court found that underlying fact
    2
    issues with respect to those claims prevented the court
    from determining whether Deputy Shelnutt was entitled
    to qualified immunity. R.219 at 25. Specifically, the court
    stated that the “requirement of announcing prior to entry
    has been clearly established, and a reasonable officer would
    know that entering without announcing his purpose or
    intent would violate the Fourth Amendment.” R.219 at 25.
    Thus, a question of fact as to whether the officers had in fact
    announced their purpose or intent prevented the court from
    ruling on qualified immunity, “because whether the law
    was violated depends on which version of the facts the jury
    believes.” R.219 at 25.
    2
    The district court briefly referred to its October 14, 2003 order,
    noting that it had addressed the illegal seizure claim and had
    denied summary judgment because it found “a jury must de-
    termine whether Shelnutt’s . . . seizure of Leaf while he was in his
    bed was reasonable.” R.172 at 18 n.3.
    No. 04-1318                                                    9
    With respect to Deputy Shelnutt’s assertion of qualified
    immunity for the Leafs’ excessive force claim, the district
    court found that a jury would have to determine whether
    Mr. Leaf had posed a threat of death or serious harm to
    Deputy Shelnutt, and whether it was unreasonable for
    Deputy Shelnutt to take more than one shot at Mr. Leaf;
    “whether Shelnutt used excessive force is completely de-
    pendant [sic] on which version of the facts the jury accepts.”
    R.219 at 26. The court cited Seventh Circuit precedents
    holding that, when an officer creates a dangerous situation
    by conducting an unreasonable search or seizure, that
    officer is stripped of qualified immunity against excessive
    force claims arising from the situation the officer created.
    R.219 at 26. Therefore, the district court concluded, a jury
    also was entitled to consider whether Deputy Shelnutt’s
    earlier unreasonable behavior rendered his actions inside
    3
    the apartment objectively unreasonable. R.219 at 27.
    II
    DISCUSSION
    A. Standard of Review
    This court reviews de novo a district court’s denial of
    summary judgment on qualified immunity grounds. See
    Sullivan v. Ramirez, 
    360 F.3d 692
    , 696 (7th Cir. 2004). Sim-
    ilarly, the question of whether an asserted federal right was
    clearly established at the time of a claimed violation is a
    question of law to be reviewed de novo on appeal. See Elder
    3
    The district court also held that Deputy Shelnutt had state law
    immunity against the Leafs’ claims for trespass, assault and bat-
    tery and negligence, and granted him summary judgment on
    those issues.
    10                                                 No. 04-1318
    v. Holloway, 
    510 U.S. 510
    , 516 (1994). Summary judgment is
    appropriate when, construing all facts and drawing all
    inferences in the light most favorable to the nonmoving
    party, there is no genuine issue of material fact for a jury to
    decide. See Sullivan, 
    360 F.3d at
    696 (citing Anderson v.
    Liberty Lobby, Inc., 
    477 U.S. 242
    , 252-55 (1986)).
    B. Qualified Immunity
    1.   Jurisdiction to Hear an Appeal from the Denial of
    Qualified Immunity
    We pause to address the issue of whether we have
    jurisdiction to hear an appeal from the denial of qualified
    immunity because it is a point of extreme conflict between
    the parties. Ordinarily, a district court’s denial of summary
    judgment is not appealable. See, e.g., Whitford v. Boglino,
    
    63 F.3d 527
    , 530 (7th Cir. 1995). However, when a district
    court has denied summary judgment on qualified immunity
    grounds, an appellate court has jurisdiction to review the
    denial of qualified immunity to the extent that the denial
    turns on a question of law. See Mitchell v. Forsyth, 
    472 U.S. 511
    , 530 (1985). On the other hand, “a defendant, entitled to
    invoke a qualified immunity defense, may not appeal a
    district court’s summary judgment order insofar as that
    order determines whether or not the pretrial record sets
    forth a ‘genuine’ issue of fact for trial.” Johnson v. Jones, 
    515 U.S. 304
    , 319-20 (1995).
    This court may not reconsider the district court’s de-
    termination that certain genuine issues of fact exist; such de-
    terminations are unappealable because they are not “final
    decisions” within the meaning of 
    28 U.S.C. § 1291
    . See
    Johnson, 
    515 U.S. at 313
    . Thus, we may not make conclusions
    about which facts the parties ultimately might be able to
    establish at trial. Such conclusions concern the “sufficiency
    No. 04-1318                                                      11
    of the evidence” and are not properly before a court of
    appeals considering the denial of qualified immunity. See 
    id.
    However, when the outcome of a question of law—
    for instance, whether a particular action violates the
    Constitution—does not depend on the outcome of a dis-
    puted factual question, we may review whether the district
    court correctly determined the question of law that it con-
    sidered. See Mitchell, 
    472 U.S. at 528
    . These are the “more
    abstract issues of law” to which an appeal of the denial of
    qualified immunity properly is limited. Johnson, 
    515 U.S. at 317
    . When conducting such a review, we “simply take,
    as given, the facts that the district court assumed when it
    denied summary judgment for that (purely legal) reason.”
    
    Id. at 319
    .
    A defendant may appeal the denial of qualified immunity
    with respect to particular claims even when he still will be
    required to go to trial on a matter separate from the claims
    for which he asserted qualified immunity. See Behrens v.
    4
    Pelletier, 
    516 U.S. 299
    , 311-12 (1996). A plaintiff often seeks
    relief for a single incident on multiple theories of liability.
    When this occurs, the defendant does not lose his right to
    appeal the denial of qualified immunity as to one theory of
    liability even when he still will be required to go to trial on
    another theory. As several of our sister circuits have recog-
    4
    The right to qualified immunity “is a right to immunity from
    certain claims, not from litigation in general; when immunity with
    respect to those claims has been finally denied, appeal must be
    available.” Behrens v. Pelletier, 
    516 U.S. 299
    , 312 (1996) (emphasis
    in original).
    12                                                   No. 04-1318
    5
    nized, the term “claim” must be employed in this context
    in a manner that is compatible with the unique, yet firmly
    established, principles established by the Supreme Court
    with respect to the doctrine of qualified immunity. Conse-
    quently, in employing the term “claim” when determining
    whether a defendant may invoke the defense of qualified
    immunity, we must keep in mind that qualified immunity
    is designed to ensure that a defendant does not stand trial
    unnecessarily on an allegation that lacked a reasonable
    grounding in established law at the time the act was
    committed. We also must keep in mind that the defense of
    qualified immunity is only effective when it is applied at a
    meaningful level of generality. This requirement ensures
    that a defendant will have to stand trial only when he could
    reasonably anticipate that his conduct may give rise to
    liability for damages. Defining “claim” in light of these
    considerations quite naturally produces a different and
    more narrow definition of the term “claim” than we would
    encounter in other contexts such as res judicata. There, in
    determining whether the same “claim” arose in earlier
    litigation, “claim” has become a surrogate for the term
    “cause of action,” and that term has been defined in turn to
    include all theories of liability arising out of the same trans-

    789 F.2d 589
    , 592-94 (7th Cir. 1986).
    Any other course would frustrate the Supreme Court’s
    directive that an appeal of the denial of qualified immunity
    “cannot be foreclosed by the mere addition of other claims
    to the suit.” See Behrens, 
    516 U.S. at 312
    ; see also 
    id.
     (“If the
    district court rules erroneously, the qualified-immunity
    right not to be subjected to pretrial proceedings will be
    eliminated, so long as the plaintiff has alleged (with or
    without evidence to back it up) violation of one ‘clearly
    established’ right . . . .”); see also International Action Center
    v. United States, 
    365 F.3d 20
    , 23-24 (D.C. Cir. 2004); Beier v.
    City of Lewiston, 
    354 F.3d 1058
    , 1063-64 (9th Cir. 2004) (hold-
    ing that it would be contrary to Behrens if “any plaintiff
    alleging multiple claims arising under a single constitu-
    tional provision would be able to circumvent a qualified
    immunity appeal as long as one of those claims has some
    merit”).

    Cooper, Federal Practice and Procedure § 4402 (2d ed. 2002):
    Foreclosure of matters that never have been litigated has
    traditionally been expressed by stating that a single “cause
    of action” cannot be “split” by advancing one part in a first
    suit and reserving some other part for a later suit. The entire
    cause of action was said to “merge” in a judgment for the
    plaintiff, leaving a new cause of action on the judgment, or
    to be subject to the “bar” of a judgment for the defendant.
    There is now a growing tendency, spurred by the vigorous
    advocacy of Allan Vestal, to substitute the word “claim” for
    the cause of action phrase.

    2.   The Qualified Immunity Framework
    Government officials performing discretionary functions
    7
    enjoy a qualified immunity from suit. See Anderson v.
    Creighton, 
    483 U.S. 635
    , 638-39 (1987). Qualified immunity
    “shield[s] [officers] from civil damages liability as long as
    their actions could reasonably have been thought consistent
    with the rights they are alleged to have violated.” 
    Id. at 638
    .
    When qualified immunity applies, a defendant is not merely
    entitled to a defense from liability; he is entitled not to stand
    trial. See Mitchell, 
    472 U.S. at 526
    .
    In determining whether qualified immunity will apply to
    shield a defendant from suit, a court undertakes a two-part
    inquiry, see Saucier v. Katz, 
    533 U.S. 194
    , 200 (2001), to assess
    “the objective reasonableness of an official’s conduct, as
    measured by reference to clearly established law,” Harlow v.
    Fitzgerald, 
    457 U.S. 800
    , 818 (1982). First, the court must ask
    the threshold question: “Taken in the light most favorable
    to the party asserting the injury, do the facts alleged show
    the officer’s conduct violated a constitutional right?” Saucier,
    533 U.S. at 201. As the Supreme Court has pointed out, “to
    deny summary judgment any time a material issue of fact
    remains . . . could undermine the goal of qualified immu-
    nity.” Id. at 202. Therefore, “[i]f no constitutional right
    would have been violated were the allegations established,
    there is no necessity for further inquiries concerning
    qualified immunity.” Id. at 201.
    7
    Because of the significant policies served by qualified immu-
    nity, a court should determine early in the proceedings whether
    qualified immunity will apply. See Saucier v. Katz, 
    533 U.S. 194
    ,
    201 (2001); see also Donovan v. City of Milwaukee, 
    17 F.3d 944
    , 947
    (7th Cir. 1994) (noting that “few individuals will enter public
    service if such service entails the risk of personal liability for
    one’s official decisions”).
    No. 04-1318                                                     15
    If the facts alleged make out a constitutional violation,
    then a court must determine “whether the right was clearly
    established.” 
    Id.
     This inquiry is a specific one: “The relevant,
    dispositive inquiry is whether it would be clear to a reason-
    able officer that the conduct was unlawful in the situation
    8
    he confronted.” 
    Id.
     at 202 (citing Wilson v. Layne, 
    526 U.S. 603
    , 615 (1999)). A right is clearly established when “[t]he
    contours of the right [are] sufficiently clear that a reasonable
    official would understand that what he is doing violates that
    right.” Anderson, 
    483 U.S. at 640
    . The action’s unlawfulness
    must be “apparent” from pre-existing law. 
    Id.
    The district court denied Deputy Shelnutt qualified
    immunity because it found that questions of fact existed
    respecting four actions that he took on May 5, 2001: (1) his
    9
    entry into Mr. Leaf’s apartment; (2) his subsequent search
    of Mr. Leaf’s apartment; (3) his conduct toward Mr. Leaf
    while Mr. Leaf was lying on the bed; and (4) the manner in
    which he shot Mr. Leaf. The district court also denied
    8
    When determining whether a constitutional right has been
    violated requires an analysis of the reasonableness of an officer’s
    conduct—for instance, in the Fourth Amendment search context—
    the reasonableness standard for the constitutional violation is
    distinct from the qualified immunity standard. See Anderson v.
    Creighton, 
    483 U.S. 635
    , 643-44 (1987). Thus, “even if a court were
    to hold that [an] officer violated the Fourth Amendment by con-
    ducting an unreasonable, warrantless search, Anderson still oper-
    ates to grant officers immunity for reasonable mistakes as to the
    legality of their actions.” Saucier, 533 U.S. at 206.
    9
    In their complaint, the Leafs did not differentiate between
    unlawful entry and illegal search; however, the district court in
    its analysis found questions of fact pertaining to both the entry
    and the search and denied summary judgment based on both of
    those questions of fact. Therefore, we address the entry and the
    ensuing search separately.
    16                                                 No. 04-1318
    Deputy Shelnutt qualified immunity for the excessive force
    claim on the ground that, because the first three actions
    listed may have violated Mr. Leaf’s constitutional rights,
    Deputy Shelnutt may have created the need for force in such
    a way that his ultimate shooting of Mr. Leaf “was tainted by
    prior unconstitutional acts.” Tom v. Voida, 
    963 F.2d 952
    , 956
    (7th Cir. 1992); see also, e.g., Sledd v. Lindsay, 
    102 F.3d 282
    ,
    287-88 (7th Cir. 1996); Yates v. City of Cleveland, 
    941 F.2d 444
    ,
    447 (6th Cir. 1991).
    C. Deputy Shelnutt’s Entry into the Apartment
    We first address the question of whether Deputy Shelnutt
    possesses qualified immunity for his entry into Mr. Leaf’s
    apartment. The district court found that there was a ques-
    tion of fact whether Deputy Shelnutt had announced his
    purpose before entering the apartment. The district court
    also determined that the requirement of “announcing prior
    to entry has been clearly established.” R.219 at 25. We re-
    spectfully disagree with the conclusion of the district court.
    The facts of this case, construed in the light most favorable
    to the Leafs, do not allege a constitutional violation with
    respect to Deputy Shelnutt’s entry. Accordingly, Deputy
    Shelnutt is entitled to qualified immunity for his entry into
    Mr. Leaf’s apartment and for the manner in which the entry
    was accomplished.
    Taking up the first question in the qualified immunity
    inquiry, we ask whether the facts, taken in the light most
    favorable to the Leafs, allege a constitutional violation. See
    Saucier, 533 U.S. at 201. A warrantless entry into a private
    home constitutes a search and presumptively is unreason-
    able under the Fourth Amendment. United States v. Rivera,
    
    248 F.3d 677
    , 680 (7th Cir.) (citing Payton v. New York, 
    445 U.S. 573
    , 585-86 (1980)), cert. denied, 
    534 U.S. 923
     (2001).
    No. 04-1318                                                      17
    However, a warrantless search is permissible “when police
    have a reasonable belief that exigent circumstances require
    immediate action and there is no time to secure a warrant.”
    United States v. Lenoir, 
    318 F.3d 725
    , 730 (7th Cir.), cert. denied,
    
    540 U.S. 841
     (2003). For instance, a warrantless search is
    permitted based on exigent circumstances “when the police
    ‘reasonably fear[] for the safety of someone inside the prem-
    ises.’ ” United States v. Jenkins, 
    329 F.3d 579
    , 581 (7th Cir.
    2003) (quoting United States v. Richardson, 
    208 F.3d 626
    , 629
    (7th Cir.), cert. denied, 
    531 U.S. 910
     (2000)). To determine
    whether there were exigent circumstances, we must “anal-
    yze the situation from the perspective of the officers at the
    scene” and must ask whether the officers had “an objectively
    reasonable belief that exigent circumstances existed.” United
    States v. Marshall, 
    157 F.3d 477
    , 482 (7th Cir.), cert. denied, 
    525 U.S. 1045
     (1998).
    Based on these principles, we agree with the district court’s
    analysis of the officers’ entry. As the district court pointed
    out, the broken window and open patio door supported an
    objectively reasonable belief that a burglary was occurring
    and that people inside the apartment were in danger.
    Furthermore, a 911 call had been placed, and, although the
    call itself was not answered, Deputy Jacobs learned from the
    caller, Murphy, that a man had been seen forcing entry into
    the apartment. We have held that a 911 call itself “can be
    enough to support [a] warrantless search[] under the exigent
    circumstances exception, particularly where . . . the caller
    identified himself.” Richardson, 
    208 F.3d at 630
    . Under the
    circumstances known to them at the time, Deputy Shelnutt
    and Deputy Jacobs had a reasonable basis to believe that an
    emergency situation justified a warrantless search of Mr.
    18                                                       No. 04-1318
    10
    Leaf’s apartment. Thus, on the record before us, we must
    conclude that the officers’ entry was justified by exigent
    circumstances.
    We next consider whether the officers’ entry into Mr. Leaf’s
    apartment was rendered unreasonable as a result of the
    officers’ failure to announce their purpose before entering.
    10
    The district court did not address whether probable cause
    existed to justify the officers’ entry. The cases on which the dis-
    trict court primarily relied in its analysis of exigent circumstances,
    United States v. Jenkins, 
    329 F.3d 579
     (7th Cir. 2003), and United
    States v. Richardson, 
    208 F.3d 626
     (7th Cir.), cert. denied, 
    531 U.S. 910
     (2000), do not address the requirement of probable cause
    separately from the existence of exigent circumstances. However,
    other cases of this court do apply the requirement of probable
    cause even in exigent circumstances. See, e.g., United States v. Rivera,
    
    248 F.3d 677
    , 680 (7th Cir.) (holding that a warrantless search is
    constitutional “where there is probable cause and exigent
    circumstances create a compelling need for official action and
    insufficient time to secure a warrant”), cert. denied, 
    534 U.S. 923
    (2001); United States v. Marshall, 
    157 F.3d 477
    , 481 (7th Cir.)
    (holding that a warrantless search and seizure inside a home is
    permitted “when probable cause and exigent circumstances ex-
    ist”), cert. denied, 
    525 U.S. 1045
     (1998); see also Minnesota v. Olson,
    
    495 U.S. 91
    , 100 (1990) (“[T]here must be at least probable cause
    to believe that [exigent circumstances] were present . . . .”).
    Circumstances constituting probable cause may include the
    reasonable belief “that illegal activity is being conducted in a
    particular place.” Jacobs v. City of Chicago, 
    215 F.3d 758
    , 769 (7th
    Cir. 2000). On the record in this case, we must conclude that the
    circumstances known to the officers at the time also gave them
    probable cause to conduct a warrantless search of Mr. Leaf’s
    apartment.
    No. 04-1318                                                        19

    The common law “knock and announce” principle, which
    requires a law enforcement officer “to announce his pres-
    ence and authority” before opening the doors of a dwelling
    12
    and entering, “forms a part of the reasonableness inquiry
    under the Fourth Amendment.” Wilson v. Arkansas, 
    514 U.S. 11
    A federal “knock and announce” statute permits a federal
    officer executing a warrant to break open a door or window and
    enter a private house if he has given “notice of his authority and
    purpose” and has been “refused admittance.” 
    18 U.S.C. § 3109
    .
    This statute codifies a common law principle, “embedded in
    Anglo-American law,” requiring a law enforcement officer to
    knock and announce himself before entering a home. Miller v.
    United States, 
    357 U.S. 301
    , 313 (1958). In 1995, the Supreme Court
    “squarely held” that the knock and announce principle “is an
    element of the reasonableness inquiry under the Fourth Amend-
    ment” and thus applies to actions by state law enforcement
    officers as well. Wilson v. Arkansas, 
    514 U.S. 927
    , 934 (1995).
    12
    As a general rule, the knock and announcement must take place
    before a law enforcement officer may “break open the doors of a
    dwelling.” Wilson, 
    514 U.S. at 929
    . Even a minor entry or an entry
    which does not cause property damage is a “breaking.” See, e.g.,
    United States v. Ramirez, 
    523 U.S. 65
    , 71-72 (1998) (officers broke one
    garage window and pointed gun through broken window);
    Sabbath v. United States, 
    391 U.S. 585
    , 589-90 (1968) (holding that
    opening of closed but unlocked door by police officers consti-
    tuted “breaking” under § 3109); Miller, 
    357 U.S. at 305-06
     (holding
    that, when officers ripped the chain off door to gain entry before
    announcing purpose to arrest, requirements of § 3109 were not
    fulfilled). In this case, the officers entered through a patio door
    which was wide open, but which was blocked by some blinds;
    Deputy Shelnutt held the blinds aside while he and Deputy
    Jacobs entered.
    In addition, once the officer has knocked and announced, he
    must wait a reasonable amount of time before entering. “[T]he
    facts known to the police are what count in judging reasonable
    waiting time . . . .” United States v. Banks, 
    540 U.S. 31
    , 39 (2003).
    20                                                     No. 04-1318
    927, 929 (1995). The principle typically is understood to
    require both a knock and an announcement prior to en-
    tering. See, e.g., United States v. Buckley, 
    4 F.3d 552
    , 558 (7th
    Cir. 1993), cert. denied sub nom. Herman v. United States, 
    510 U.S. 1124
     (1994). The announcement generally must relate
    both the officer’s identity as a member of law enforcement
    13
    and his purpose or authority. See Wilson, 
    514 U.S. at 929
    .
    Because the knock and announce principle is a part of
    the reasonableness inquiry according to which any search is
    judged, it is relevant to searches conducted without a
    warrant under some recognized exigency, as well as those
    14
    authorized in advance by a warrant.
    The knock and announce principle is but one part of
    the reasonableness inquiry to be conducted under the
    Fourth Amendment. See Wilson, 
    514 U.S. at 929
    . Therefore,
    the elements described above are not applied strictly in
    13
    See also 3 Wayne R. LaFave, Search and Seizure: A Treatise
    On the Fourth Amendment § 4.8(c) (3d ed. 1996) (“It would seem
    that [the requirement described in Wilson v. Arkansas] is not in-
    tended to be different from the common ‘authority and purpose’
    assertion, as the authority cannot be established without a refer-
    ence to purpose, in this context, execution of a search warrant.”).
    14
    Although most of the cases developing the contours of the
    knock and announce principle have been decided in the context
    of police officers executing search or arrest warrants, the guide-
    lines developed in those cases also apply to situations in which
    police officers conduct warrantless searches. The requirements of
    § 3109 have been held to cover warrantless searches and war-
    rantless entries to arrest made by federal agents. See, e.g., Sabbath,
    
    391 U.S. at 588
    ; Miller, 
    357 U.S. at 308-09
     (“The requirement . . .
    applies . . . whether the arrest is to be made by virtue of a
    warrant, or when officers are authorized to make an arrest for a
    felony without a warrant.”). See also 1 William E. Ringel, Searches
    & Seizures, Arrests and Confessions § 6:7 (2d ed. 2004).
    No. 04-1318                                                        21
    every situation. See, e.g., id. at 934 (holding that “[t]he Fourth
    Amendment’s flexible requirement of reasonableness
    should not be read to mandate a rigid rule of announcement
    15
    that ignores countervailing law enforcement interests”).
    We are mindful that the principle of “knock-and-announce,”
    as an “element of the reasonableness inquiry,” has never
    been a “rigid” rule. Id. Although “in some circumstances an
    15
    For instance, this court has held that, in certain circumstances,
    the announcement of purpose is not necessary:
    [W]hen it is clear that someone is at home, officers must ex-
    plain not just who they are but also why they are there. . . .
    But where . . . officers have knocked and announced “Police,”
    with no answer whatsoever, and there are no signs that
    anyone is at home, . . . [the] common law rules . . . may be
    complied with, in spirit at least, even if the officers neglect to
    state what their business is.
    United States v. Leichtnam, 
    948 F.2d 370
    , 374 (7th Cir. 1991)
    (emphasis in original). At least one of our sister circuits has held
    that, in certain circumstances, the knock is not required. See, e.g.,
    United States v. Mendoza, 
    281 F.3d 712
    , 717 (8th Cir.) (holding that
    police had acted consistently with purposes underlying the knock
    and announce principle, even when no knock was given, when
    officers shouted warning and door already was off its hinges),
    cert. denied, 
    537 U.S. 1004
     (2002).
    When made, “[a] knock and announcement must be loud
    enough to be heard.” Leichtnam, 
    948 F.2d at 374
     (approving an
    announcement made “slightly above conversational level”) (in-
    ternal quotations omitted); cf. United States v. Spriggs, 
    996 F.2d 320
    , 322-23 (D.C. Cir.) (holding that announcement was “suffi-
    cient to alert the residents of the apartment” where “reasonably
    audible” and “slightly above a normal tone of voice” and made
    at 7:45 a.m., when residents likely to “be awake and responsive”)

    officer’s unannounced entry into a home might be a viola-
    tion of the Fourth Amendment,” in other circumstances, an
    unannounced entry may be justified by “countervailing law
    enforcement interests.” 
    Id.
    Courts have recognized three sets of circumstances which
    constitute exceptions to the knock and announce principle.
    “In order to justify a ‘no-knock’ entry, the police must have
    16
    a reasonable suspicion that knocking and announcing their
    presence, under the particular circumstances, would be [(1)]
    17
    dangerous or [(2)] futile, or [(3)] that it would inhibit
    effective investigation of the crime by . . . allowing the
    destruction of evidence.” Richards v. Wisconsin, 
    520 U.S. 385
    ,
    394 (1997). This court has described these situations,
    in which “executing [a] search in a no-knock fashion” is
    justified, as “exigent circumstances.” United States v. Singer,
    
    943 F.2d 758
    , 762 (7th Cir. 1991); see also Sledd, 
    102 F.3d at 288
    .
    16
    The showing required by the reasonable suspicion standard
    is “not high,” and certainly requires less than probable cause.
    Richards v. Wisconsin, 
    520 U.S. 385
    , 394 (1997).
    17
    Deputy Shelnutt argues that an announcement of purpose
    should be excused as futile on the ground that Mr. Leaf was asleep.
    However, the futility exception to the knock and announce prin-
    ciple applies when the occupant of the premises to be entered
    most likely already knows why the officers are approaching. See,
    e.g., Miller, 
    357 U.S. at 310
     (“It may be that, without an express
    announcement of purpose, the facts known to officers would
    justify them in being virtually certain that the [occupant] already
    knows their purpose so that announcement would be a useless
    gesture.”); United States v. Tracy, 
    835 F.2d 1267
    , 1270 (8th Cir.)
    (“[T]he officers could have justifiably believed defendants were
    anticipating their arrival and knew their purpose. Thus, announc-
    ing their purpose would have been a useless gesture.”), cert.
    denied, 
    486 U.S. 1014
     (1988). On the record in this case, we must
    conclude that the futility exception does not apply.
    No. 04-1318                                                       23
    Most of the cases explaining the danger exception to the
    knock and announce principle have taken place in the con-
    18
    text of searches pursuant to warrant. However, this court
    also has excused officers’ failure to comply with the knock
    18
    See, e.g., Ramirez, 
    523 U.S. at 71
     (holding that police had a rea-
    sonable suspicion that “knocking and announcing their presence
    might be dangerous,” justifying their unannounced entry to
    execute an arrest warrant, when a “confidential informant had
    notified the police” that a man “with a violent past who report-
    edly had access to a large supply of weapons” “might be inside
    respondent’s home, and an officer had confirmed that possibility”).
    This court has excused compliance with the knock and announce
    principle in circumstances presenting danger to officers executing
    warrants. See, e.g., United States v. Sutton, 
    336 F.3d 550
    , 554 (7th
    Cir. 2003) (excusing “less than full compliance” with knock and
    announce principle by officers executing search warrant when pit
    bulls had been seen on the property, individuals with weapons
    convictions had been seen entering the house and configuration
    of house “provided no cover”); United States v. Gambrell, 
    178 F.3d 927
    , 929 (7th Cir.) (holding that, when officer knew before
    entering that the occupant typically “answered the door wearing
    a .25 caliber gun in her front pocket; that she and her roommate
    regularly carried guns in the apartment; [and] that . . . there were
    other guns . . . in the apartment,” there was “a reasonable
    suspicion that an announced entry would have subjected the
    officers to a substantial risk of harm”), cert. denied, 
    528 U.S. 920
    (1999); United States v. Buckley, 
    4 F.3d 552

    ,
    1267 (7th Cir.) (concluding that “exigent circumstances justified
    disregarding the knock and announce requirement” where
    officers executing search warrant “had specific knowledge that
    the [occupant] was in possession of a firearm, and that he had
    previously fired it in the hallway outside his apartment”),
    cert. denied, 
    506 U.S. 882
     (1992).

    and announce principle when the officers were making a
    warrantless entry and the circumstances gave rise to a
    reasonable belief that knocking and announcing would be
    dangerous to the officers. United States v. Hardy, 
    52 F.3d 147
    ,
    150 (7th Cir.), cert. denied, 
    516 U.S. 877
     (1995). In Hardy, “the
    same exigent circumstances” that justified an officer’s war-
    rantless search of a hotel room “also excuse[d] a failure to
    knock and announce.” 
    Id.
     The circumstances known to the
    police in that case led them to “reasonably believe that their
    19
    safety or the safety of others” was at risk. 
    Id. at 149
    .
    In this case, the circumstances reflected in the record com-
    pel the conclusion that the officers had a reasonable basis to
    conclude that knocking and announcing themselves would
    have been dangerous. Although Deputy Jacobs had not seen
    or heard a person within the apartment during his approxi-
    mately eight-minute observation, there were several signs
    that someone other than the apartment’s lawful occupant
    had entered it. For instance, the sliding patio door had been
    left open and an ice chest had been pushed up against the
    apartment’s front door; this would have been consistent
    with the presence of a burglar attempting to block all but one
    path of entry and exit.
    The officers had no conclusive information that the
    apartment was empty. The residents told Deputy Jacobs
    they had seen a man forcing entry into the apartment, and
    Deputy Jacobs did not witness anyone leave the apartment
    during his eight-minute observation prior to Deputy Shelnutt’s
    19
    In Hardy, the room’s occupant was a murder suspect who knew
    that the police were pursuing him, had a history of committing
    crimes using guns and was known to be armed with a shotgun;
    also, women and children were known to be in the room with
    him. See United States v. Hardy, 
    52 F.3d 147
    , 149 (7th Cir.),
    cert. denied, 
    516 U.S. 877
     (1995).
    No. 04-1318                                                       25
    arrival. Deputy Jacobs had shone a flashlight upon the
    broken window and open patio door; that alone could have
    alerted a burglar to the need to remain still and silent. Al-
    though the interior of the apartment did not appear to have
    been disturbed, this may have convinced the officers that an
    intruder still was present. Furthermore, the officers had very
    little information about the identity or temperament of the
    person who may have been inside except that Murphy had
    told Deputy Jacobs the man was belligerent. Indeed, all
    signs pointed to the need to investigate and to exercise
    caution in doing so.
    Taking all the facts and circumstances in the light
    most favorable to the Leafs, we still must conclude that
    Deputy Shelnutt did not violate the Fourth Amendment by
    entering Mr. Leaf’s apartment without knocking and with-
    20
    out announcing his purpose.
    20
    We note that our holding is based on the specific facts pre-
    sented by this case and not on a general invocation of exigent
    circumstances. The Supreme Court has instructed that, when
    “exigent circumstances” might have justified officers’ warrantless
    entry into a home without a knock, if the record does not reflect
    “any substantial basis for excusing the failure of the agents . . . to
    announce their authority and purpose,” the entry violates the
    Fourth Amendment. Sabbath, 
    391 U.S. at 591
    . When agents
    making a warrantless entry “ha[ve] no basis for assuming [the
    occupant is] armed or might resist arrest, or that [the undercover
    agent present is] in any danger,” then compliance with the knock
    and announce principle will not be excused. 
    Id.
     This guidance
    accords with the Court’s later directive, made in Richards, that
    officers must have a “reasonable suspicion,” based on the
    circumstances, that one or more of the exceptions to the knock
    and announce principle applies. Richards, 
    520 U.S. at 394
    . There
    is no general rule permitting officers to enter a private residence

    D. The Protective Sweep
    We next address the search that Deputy Shelnutt con-
    ducted inside Mr. Leaf’s apartment. The district court
    determined that there was a question as to whether that
    search was carried out unreasonably. Specifically, the court
    found that, because Deputies Shelnutt and Jacobs used
    tactical lights, because they did not identify themselves
    as law enforcement officers or illuminate their badges,
    and because they did not wake Mr. Leaf immediately after
    finding him, a jury could determine that Deputy Shelnutt
    had acted in an objectively unreasonable manner in search-
    ing the apartment. The district court also found that there
    was a question as to whether Deputy Shelnutt’s conduct
    during the search of the apartment unreasonably created the
    need for force. On the record in this case, we respectfully
    disagree with the district court’s analysis. In our view,
    Deputy Shelnutt is entitled to qualified immunity because
    his search of the apartment did not violate the Fourth
    Amendment.
    Deputy Shelnutt does not dispute any of the factual find-
    ings made by the district court with respect to his search of
    20
    (...continued)
    without complying with the knock and announce principle
    whenever exigent circumstances are present; in fact, the Supreme
    Court in Richards forbade a blanket rule which would excuse
    compliance for an entire class of cases. 
    Id.
     To hold that the knock
    and announce principle may be disregarded any time exigent
    circumstances justify a warrantless search would be to eviscerate
    Richards. Rather, in this case, the “countervailing law enforcement
    interests,” Wilson, 
    514 U.S. at 934
    , convince us that it was
    reasonable for the officers to protect their safety by complying
    less than fully with the knock and announce principle in a
    situation of questionable security.
    No. 04-1318                                                       27
    the apartment: for instance, that neither he nor Deputy Jacobs
    identified themselves after entering the apartment; that both
    officers lit the apartment with the tactical lights attached to
    their guns; that neither officer illuminated his badge; and
    that the officers did not attempt to wake Mr. Leaf immedi-
    ately after finding him, but instead searched the rest of the
    apartment before waking him. However, Deputy Shelnutt
    does contend that he is entitled to qualified immunity for
    the search on the ground that it was justified under the pro-
    tective sweep doctrine described in Maryland v. Buie, 
    494 U.S. 325
    , 327 (1990). A “protective sweep” has been defined
    as “a quick and limited search of premises, incident to an
    arrest and conducted to protect the safety of police officers
    or others . . . [and] narrowly confined to a cursory visual
    inspection of those places in which a person might be
    hiding.” 
    Id.
     Although a protective sweep invades a home-
    owner’s privacy, such a search tactic may be “reasonable
    when weighed against ‘the need for law enforcement
    officers to protect themselves and other prospective victims
    of violence.’ ” 
    Id. at 332
     (quoting Terry v. Ohio, 
    392 U.S. 1
    , 24
    (1968)).
    A protective sweep, limited to “look[ing] in closets and
    other spaces immediately adjoining the place of arrest,” is
    justified “incident to [an] arrest . . . as a precautionary mat-
    ter and without probable cause or reasonable suspicion.” Id.
    at 334. A search beyond those parameters is justified when
    there are “articulable facts which, taken together with the
    rational inferences from those facts, would warrant a rea-
    sonably prudent officer in believing that the area to be swept
    harbors an individual posing a danger to those on the arrest
    scene.” Id. “[A] protective sweep . . . is . . . not a full search of
    the premises, but may extend only to a cursory inspection
    of those spaces where a person may be found. The sweep
    lasts no longer than is necessary to dispel the reasonable
    28                                                    No. 04-1318
    suspicion of danger . . . .” Id. at 335-36. We have recognized
    generally that while entry into a dwelling typically requires
    a search warrant founded on probable cause, a “quick in-
    spection[ ] may be justified by lower degrees of suspicion.”
    United States v. Brown, 
    64 F.3d 1083
    , 1086 (7th Cir. 1995); see
    also United States v. Concepcion, 
    942 F.2d 1170
    , 1173 (7th Cir.
    1991) (“How much cause agents need to do something
    depends on how deeply they invade the zone of privacy.”).
    We have noted on previous occasions that the inquiry
    whether a protective sweep was reasonable is “necessarily
    a very fact-specific one.” United States v. Burrows, 
    48 F.3d 1011
    , 1016 (7th Cir.), cert. denied, 
    515 U.S. 1168
     (1995). Further-
    more, “the circumstances of the particular encounter [must]
    be assessed carefully in light of the overarching policy con-
    cerns articulated in Buie and in its first cousins, Terry and
    Long.” Id.; see also Terry, 
    392 U.S. 1
    ; Michigan v. Long, 
    463 U.S. 1032
     (1983). Those policy concerns include a proper re-
    gard for the safety of police officers, who “have an interest
    in ensuring their safety when they lawfully enter a house . . . .
    That interest justifies their ensuring that the dwelling does
    not harbor another person who is dangerous and who unex-
    pectedly could launch an attack.” Burrows, 
    48 F.3d at
    1015-
    21
    16.
    21
    Beyond the protective sweep doctrine, another line of cases
    recognizes that law enforcement officers may conduct a quick
    and limited search of a dwelling which they have entered based
    on “legitimate concerns” about the safety of the occupants. United
    States v. Brown, 
    64 F.3d 1083
    , 1086 (7th Cir. 1995) (“[W]ith some
    (though far from strong) reason to fear for Bonds’s safety, the
    agents could take some steps to protect her.”); see also United
    States v. Arch, 
    7 F.3d 1300
    , 1303 (7th Cir. 1993) (finding a limited
    search of dwelling place was lawful under the exigent circum-
    (continued...)
    No. 04-1318                                                       29
    The Leafs contend that the search conducted by
    Deputy Shelnutt upon entering the apartment was not justi-
    fied, because the cases have approved protective sweeps
    incident to arrest. The Leafs submit that the officers, when
    they entered the apartment, did not intend to make an
    22
    arrest. However, the Leafs’ argument misapprehends the
    lineage of the protective sweep. Although Buie recognizes
    that a protective sweep “occurs as an adjunct to the serious
    step of taking a person into custody for the purpose of
    prosecuting him for a crime,” the protective sweep doctrine
    also is justified by the concerns that an officer conducting an
    in-home arrest is at a “disadvantage” and that he is suscepti-
    ble to “[a]n ambush in a confined setting of unknown
    configuration.” Buie, 
    494 U.S. at 333
    . This concern for officer
    safety derives from the same principles recognized in Terry.
    See United States v. Arch, 
    7 F.3d 1300
    , 1303 (7th Cir. 1993),
    cert. denied, 
    510 U.S. 1139
     (1994). The protective sweep is
    justified by the need, based on the facts known to a law
    enforcement officer, to ensure officer and bystander safety.
    Buie, 
    494 U.S. at 327
    . The underlying rationale for the
    protective sweep doctrine is the principle that police officers
    should be able to ensure their safety when they lawfully
    enter a private dwelling. Arch, 
    7 F.3d at 1303
    . That rationale
    also applies in this situation. The officers entered in order to
    ascertain whether a burglary had occurred; they had
    21
    (...continued)
    stances exception to the warrant requirement when police feared
    injured individuals were inside), cert. denied, 
    510 U.S. 1139
     (1994).
    22
    This court has recognized that the logic of “Buie assumes that
    the police already are lawfully present in the home to arrest its
    occupant and that a sweep is necessary to avert any immediate
    danger posed by others on the premises.” Arch, 
    7 F.3d at 1303
     (cit-
    ing Buie, 
    494 U.S. at 327, 333, 336
    ).

    substantial reason to believe their safety might have been at
    risk. Accordingly, it was not necessary for the officers to
    have made an arrest in order for their search of the apart-
    ment to be justified; the only question is whether the search
    was objectively reasonable.
    We have reviewed the record in this case and must con-
    clude that the decision to conduct a protective search was
    reasonable, and that the sweep was conducted in a rea-
    sonable manner. The officers, already lawfully present in
    the apartment, had reason to believe that they might be
    faced with an ongoing crime or an individual in danger.
    Therefore, they were justified in conducting a brief, three-
    minute sweep, extending no more broadly than necessary to
    ascertain whether those suspicions were correct. In light of
    the policies expressed in Buie, the officers were entitled to
    ensure their own safety after entering a dwelling which they
    suspected was the target of a crime, and from which no
    person had been seen emerging. The intrusiveness of the
    search was minimal, and its scope was limited appropriately
    by its purposes.
    Furthermore, the officers did not act unreasonably in
    speaking in low tones and using the tactical lights on their
    weapons. They had entered Mr. Leaf’s apartment on the
    suspicion that someone other than the lawful occupant
    might be present inside. Given the facts known to the
    deputies at the time of their entry—the open screen door,
    the broken window, the front door that had been kicked in,
    the dark apartment, the unanswered 911 call and the fact
    that someone was seen forcing entry into the apartment—a
    reasonable officer could have believed that the apartment
    potentially harbored a dangerous intruder. Even after they
    had witnessed Mr. Leaf lying on the bed, the officers could
    not have been sure that they would not be surprised by
    another person until they had conducted a protective sweep.
    No. 04-1318                                                    31
    We also must conclude that, based on the circumstances fac-
    ing them, the officers behaved reasonably by not waking
    Mr. Leaf immediately. Furthermore, until they had deter-
    mined that no dangerous person was hiding in the apart-
    ment, the officers behaved reasonably in using the tactical
    lights on their guns and remaining quiet.
    In light of these considerations, we must conclude that the
    Fourth Amendment was not violated by the very limited
    protective sweep that Deputy Shelnutt conducted. Approv-
    ing this search does not pervert the Fourth Amendment “to
    achieve ends other than those acknowledged as legitimate.”
    23
    Burrows, 
    48 F.3d at 1017
    . Based on our analysis of Deputy
    Shelnutt’s entry into the apartment and his brief search of
    the apartment, we must conclude that Deputy Shelnutt is
    entitled to qualified immunity for the Leafs’ illegal search
    claim. The conclusion that Deputy Shelnutt did not conduct
    an unreasonable search of the apartment compels the further
    conclusion that his entry and search did not unreasonably
    create the need for his later use of force. See, e.g., Sledd, 
    102 F.3d at 287-88
    . The question of whether other actions taken
    by the deputies constituted excessive use of force, however,
    is not before us on this appeal.
    23
    We note that, even if we had found that the Fourth Amendment
    forbade the search at issue here, Deputy Shelnutt still would be
    entitled to qualified immunity, because it is not clearly estab-
    lished that such a sweep violates the Constitution. Decisions from
    both the Supreme Court of the United States and this court have
    sketched the outlines of the protective sweep in terms of the
    reasonable suspicion standard, emphasizing a concern for the
    safety of law enforcement officers. Therefore, under these
    circumstances, the unlawfulness of the protective sweep would
    not have been apparent to a reasonable officer.

    E. Illegal Seizure
    We turn next to Deputy Shelnutt’s assertion that he is
    entitled to qualified immunity for the Leafs’ illegal seizure
    claim. In its order of October 14, 2003, the district court
    denied the Leafs’ motion for partial summary judgment on
    their illegal seizure claim. The district court determined that
    the officers had seized Mr. Leaf in his bed, but found a
    genuine issue of triable fact existed as to whether the seizure
    was unreasonable in violation of the Fourth Amendment.
    Although Deputy Shelnutt asserted qualified immunity in
    his response to the Leafs’ summary judgment motion, the
    district court did not address qualified immunity for the
    illegal seizure claim. The district court only addressed qua-
    24
    lified immunity later, in its January 6, 2004 order. There,
    the court noted generally that “fact issues . . . on the claims
    for unlawful entry, search and seizure, and excessive force . . .
    prevent the Court from deciding as a matter of law whether
    Shelnutt is entitled to qualified immunity on those claims.”
    R.219 at 25.
    24
    We cannot accept the Leafs’ contention that Deputy Shelnutt’s
    appeal of this issue on qualified immunity grounds is not timely.
    It is true that, when the Leafs earlier moved for partial summary
    judgment on their illegal seizure claim, Deputy Shelnutt replied
    to that motion by arguing that his actions were constitutional and
    that, in the alternative, he was entitled to qualified immunity. In
    ruling on the motion, the district court denied the Leafs’ motion
    for summary judgment on the ground that there were genuine
    issues of triable fact. Deputy Shelnutt therefore prevailed on this
    motion on a ground other than qualified immunity. The district
    court never reached the alternate issue of qualified immunity.
    Notably, when the district court reached the qualified immunity
    issue in its later order, it gave no indication that it had addressed
    the issue earlier.
    No. 04-1318                                                 33
    1.   Whether a Seizure Occurred
    We begin our review of the district court’s decision to
    deny Deputy Shelnutt qualified immunity for the seizure by
    asking whether the facts alleged, taken in the light most
    favorable to the Leafs, show that Deputy Shelnutt violated
    the Constitution. See Saucier, 533 U.S. at 201. The Fourth
    Amendment prohibits unreasonable seizures. See, e.g.,
    California v. Hodari D., 
    499 U.S. 621
    , 624 (1991). In order to
    determine whether Deputy Shelnutt seized Mr. Leaf in
    violation of the Fourth Amendment, we must engage in a
    two-part inquiry. See White v. City of Markham, 
    310 F.3d 989
    ,
    993 (7th Cir. 2002). We first consider whether Mr. Leaf was
    seized in his bedroom on May 5, 2001; if we conclude that
    he was seized, we then must determine whether the seizure
    was unreasonable. See 
    id.
    A seizure has been defined as a “governmental termi-
    nation of freedom of movement through means intentionally
    applied.” Brower v. County of Inyo, 
    489 U.S. 593
    , 597 (1989)
    (emphasis in original). A person is seized “only if, in view
    of all of the circumstances surrounding the incident, a
    reasonable person [in the subject’s position] would have
    believed that he was not free to leave.” United States v.
    Mendenhall, 
    446 U.S. 544
    , 554 (1980). As well, for a seizure to
    have taken place, “the subject [must] actually yield to a
    show of authority from the police or be physically touched
    by the police.” Tom v. Voida, 
    963 F.2d 952
    , 957 (7th Cir. 1992)
    (citing Hodari D., 
    499 U.S. at 626
    ).
    In concluding that Mr. Leaf was seized, the district court
    determined that a reasonable person in Mr. Leaf’s situation
    would have believed that he was not free to leave. The
    Supreme Court has noted that a reasonable person might
    not believe he was free to leave when faced with “the threat-
    ening presence of several officers, the display of a weapon
    34                                                No. 04-1318
    by an officer, some physical touching of the person of the
    citizen, or the use of language or tone of voice indicating
    that compliance with the officer’s request might be com-
    pelled.” Mendenhall, 
    446 U.S. at 554
    . Furthermore, this court
    has noted some other factors that might influence a reason-
    able individual to believe that he was not free to leave:
    “whether the encounter occurred in a public or private place;
    whether the suspect was informed that he was . . . free to
    leave; . . . whether there was physical touching, display of
    weapons, or other threatening conduct; and whether the
    suspect eventually departed the area without hindrance.”
    United States v. Scheets, 
    188 F.3d 829
    , 836-37 (7th Cir. 1999),
    cert. denied, 
    528 U.S. 1096
     (2000).
    In light of the fact that two police officers had their guns
    and tactical lights pointed at Mr. Leaf, while he lay in his
    bed in his own residence in the middle of the night, we
    agree with the district court that a reasonable person would
    not have believed that he was free to leave. However, this
    issue is not dispositive of the ultimate question of whether
    a seizure occurred. “[T]he objective test of Mendenhall states
    a necessary, but not a sufficient, condition for seizure.” Tom,
    
    963 F.2d at 957
    . We must also consider whether Mr. Leaf
    was physically touched by the officers or whether he
    submitted to their authority, before we may conclude that
    a seizure occurred. 
    Id.
    The district court thought that the question of seizure
    turned on whether or not Mr. Leaf submitted to the officers’
    show of authority. However, because a seizure must be
    accomplished “through means intentionally applied,” it is not
    the case that a seizure occurs every time there is a “govern-
    mentally desired termination of an individual’s freedom of
    movement.” Brower, 
    489 U.S. at 597
     (emphases in original).
    Where police seek to stop someone, but the subject is “in
    fact stopped . . . by a different means,” no seizure occurs. 
    Id.
    If Mr. Leaf’s failure to flee can be attributed to the fact that
    No. 04-1318                                                       35
    he was asleep or otherwise unconscious, we think that it
    cannot be said that the officers terminated his freedom of
    movement through their show of authority. Thus, the fact
    that Mr. Leaf did not flee, taken alone, cannot establish that
    he was seized.
    In determining that a seizure had occurred, the district
    court did not make a finding as to whether or not
    Deputy Shelnutt actually touched Mr. Leaf. In fact, in its
    January 6, 2004 order denying Deputy Shelnutt qualified
    immunity, the district court stated that whether
    Deputy Shelnutt had touched Mr. Leaf was “irrelevant to
    the present motion.” R.219 at 4. We may not reconsider the
    district court’s apparent conclusion that there was a ques-
    tion of fact as to whether any touching occurred, nor may we
    express an opinion about which facts the parties may ulti-
    mately be able to establish at trial. Johnson, 
    515 U.S. at 313
    .
    The Supreme Court has noted that “[t]he word ‘seizure’
    readily bears the meaning of a laying on of hands or ap-
    plication of physical force to restrain movement, even when
    it is ultimately unsuccessful.” Hodari D., 
    499 U.S. at 626
    ; see
    
    id.
     (“An arrest requires . . . physical force . . . .”). However,
    the Court has also said that, when a person merely is tapped
    on the shoulder by law enforcement agents attempting to
    get that person’s attention, no seizure occurs. See INS v.
    25
    Delgado, 
    466 U.S. 210
    , 220-21 (1984). This observation
    conforms to the Court’s directive that a seizure is a “gov-
    ernmental termination of freedom of movement.” Brower, 
    489 U.S. 25
    See also Martinez v. Nygaard, 
    831 F.2d 822
    , 826-27 (9th Cir. 1987)
    (holding that man was not seized when officers grabbed him “to
    get his attention” and then released him); cf. United States v.
    Sokolow, 
    808 F.2d 1366
    , 1369 (9th Cir. 1987) (holding that man was
    seized when officers grabbed him and moved him to a seat for
    questioning before releasing him), rev’d on other grounds, 
    490 U.S. 1
     (1989) (assuming, without deciding, that a seizure occurred).
    36                                                  No. 04-1318
    at 597 (emphasis added). Here, Deputy Shelnutt sought to
    get Mr. Leaf’s attention, not to terminate his freedom of
    movement. Thus, the Leafs have not alleged the first part of
    a Fourth Amendment violation; on these facts, they cannot
    show that Mr. Leaf was seized. Therefore, we must conclude
    that there was no unreasonable seizure in violation of the
    Fourth Amendment, and that Deputy Shelnutt is entitled to
    qualified immunity as a defense against the Leafs’ illegal
    seizure claim.
    2.   Whether a Seizure was Unreasonable
    In the alternative, we note that, even if Deputy Shelnutt’s
    conduct towards Mr. Leaf could be considered a seizure, it
    was reasonable as a matter of law. The reasonableness of a
    seizure is measured by weighing the governmental need to
    seize “against the invasion into one’s privacy that the . . .
    seizure entails.” United States v. Sechrist, 
    640 F.2d 81
    , 86 (7th
    Cir. 1981). When a police officer suspects that criminal
    activity is afoot, “[a] brief stop of a suspicious individual, in
    order to determine his identity . . . may be most reasonable
    in light of the facts known to [an] officer at the time.” Adams
    v. Williams, 
    407 U.S. 143
    , 146 (1972) (citing Terry, 
    392 U.S. at 21-22
    ). This court has held that “[a]n investigatory stop not
    amounting to an arrest is authorized if the officer making
    the stop is ‘able to point to specific and articulable facts’ that
    give rise to a reasonable suspicion of criminal activity.”
    United States v. Tilmon, 
    19 F.3d 1221
    , 1224 (7th Cir. 1994)
    (quoting Terry, 
    392 U.S. at 21-22
    ).
    We judge the reasonableness of an investigatory stop by
    considering: “(1) whether the police were aware of specific
    and articulable facts giving rise to reasonable suspicion; and
    (2) whether the degree of intrusion was reasonably related
    to the known facts.” Id.; see also Scheets, 
    188 F.3d at 837
    .
    No. 04-1318                                                   37
    When evaluating the reasonableness of an investigatory
    stop, we consider the totality of the circumstances with
    which the officers were faced, in terms of both “the experi-
    ence of the law enforcement agent and the behavior and
    characteristics of the suspect,” and “exclud[ing] any facts
    learned thereafter.” United States v. Odum, 
    72 F.3d 1279
    , 1284
    (7th Cir. 1995).
    Even taking the facts in the light most favorable to the
    Leafs, as we must when considering qualified immunity,
    Saucier, 533 U.S. at 201, we think that Deputy Shelnutt’s
    conduct was reasonable. First, Deputy Shelnutt was aware
    of sufficient specific and articulable facts to give rise to rea-
    sonable suspicion that crime was afoot. As we have noted
    numerous times, the officers suspected someone had broken
    into the apartment. Furthermore, as the district court pointed
    out, “the officers did not know the identity of the [appar-
    ently] sleeping man.” R.172 at 9. It is not important that the
    behavior that the officers observed (Mr. Leaf lying on his
    bed, apparently sleeping) could have been innocent behavior.
    Innocent characteristics, when “taken together,” may add
    up to reasonable suspicion. United States v. Sokolow, 
    490 U.S. 1
    , 9 (1989). Indeed, “there could . . . be circumstances in
    which wholly lawful conduct might justify the suspicion
    that criminal activity was afoot.” Reid v. Georgia, 
    448 U.S. 438
    , 441 (1980) (per curiam) (citing Terry, 
    392 U.S. at 27-28
    ).
    The degree of intrusion also was reasonably related to the
    facts known to the officers while they were in the apartment.
    The record reflects a minimally intrusive stop. Faced with
    signs of a break-in and already lawfully within the apart-
    ment, Deputy Shelnutt wanted to awaken the man lying on
    the bed to determine who he was and why he was present.
    Thus, he moved to nudge the man awake. This behavior
    hardly can be called intrusive.
    38                                                No. 04-1318
    The Leafs argue that Deputy Shelnutt should have at-
    tempted to wake Mr. Leaf by a means other than approach-
    ing him to nudge him. However, the Supreme Court has
    held that the reasonableness of an officer’s actions “does not
    turn on the availability of less intrusive investigatory
    techniques.” Sokolow, 
    490 U.S. at 11
    . Therefore, the manner
    in which Deputy Shelnutt approached Mr. Leaf does not
    render unreasonable any seizure that occurred.
    It also is clear that any seizure that might have occurred
    did not last any longer than reasonably necessary. At most,
    Deputy Shelnutt engaged in a brief touch. See, e.g., Hodari D.,
    
    499 U.S. at 625
     (no continuing seizure after fugitive breaks
    free of officer’s grasp). The Supreme Court has stated that a
    court reviewing the duration of an investigative stop should
    ask “whether the police diligently pursued a means of
    investigation that was likely to confirm or dispel their
    suspicions quickly, during which time it was necessary to
    detain the defendant.” United States v. Sharpe, 
    470 U.S. 675
    ,
    686 (1985). The means of investigation employed by the
    officers in this case, rousing a man to determine his identity,
    certainly constituted a quick way to gather information—
    perhaps the means used were the only way for the officers
    to learn what they needed to know. Furthermore, when
    “police are acting in a swiftly developing situation,” as was
    the case here, a court must not “indulge in unrealistic sec-
    ond-guessing.” 
    Id.
    Viewing the facts of this case in the light most favorable
    to the Leafs, we must conclude that there has been no show-
    ing that Deputy Shelnutt violated Mr. Leaf’s constitutional
    rights by his conduct towards Mr. Leaf as Mr. Leaf lay in his
    bed. There was no seizure, and furthermore, Deputy Shelnutt’s
    behavior was reasonable. Therefore, he is entitled to qua-
    lified immunity as a defense to the Leafs’ claim for illegal
    seizure.
    No. 04-1318                                                39
    F. Excessive Force
    The district court denied Deputy Shelnutt qualified im-
    munity for the Leafs’ excessive force claim on two grounds.
    First, the court found that a jury would have to determine
    whether Deputy Shelnutt’s use of force itself was justified as
    a matter of law, based on the threat presented by Mr. Leaf.
    Deputy Shelnutt does not ask that we address the district
    court’s decision on this issue. Thus, Deputy Shelnutt’s im-
    mediate use of force in the encounter with Mr. Leaf—
    whether Mr. Leaf threatened “death or serious physical
    harm” and “whether it was unreasonable for Shelnutt to
    take the second shot at Leaf”—remains for adjudication.
    R.219 at 26.
    Second, the district court noted that there was a question
    for the jury as to whether the unreasonableness of
    Deputy Shelnutt’s actions leading up to the encounter in the
    bedroom “unreasonably created the need for force.” R.219 at
    26-27. Based on our analysis of the preceding issues, we
    must conclude that the district court’s second ground was
    an incorrect basis for denying qualified immunity. Because
    we have determined that Deputy Shelnutt is entitled to qua-
    lified immunity against the claims that he acted unreason-
    ably in searching the apartment and in seizing Mr. Leaf, we
    also must conclude that he is entitled to qualified immunity
    against any claim that he unreasonably created the need for
    force.
    G. Failure to Intervene
    The district court also denied Deputy Shelnutt summary
    judgment on the Leafs’ claim that he failed to intervene
    in Deputy Jacobs’ unlawful conduct. Because we have deter-
    mined that the officers’ actions inside the apartment con-
    stituted neither an illegal search nor an illegal seizure, we
    40                                             No. 04-1318
    must conclude that the Leafs do not have a cognizable claim
    against Deputy Shelnutt for failing to intervene in Deputy
    Jacobs’ actions.
    The only remaining conduct of which the Leafs complain
    is the use of force against Mr. Leaf when Deputy Shelnutt
    shot him, causing his death. As we noted above, a claim for
    excessive force based on the shots fired at Mr. Leaf remains
    before the district court. However, Deputy Shelnutt engaged
    in the act of shooting, not Deputy Jacobs. Therefore, as
    Deputy Shelnutt correctly argues, there is no basis for the
    failure to intervene claim.
    Conclusion
    For the reasons set forth in this opinion, the judgment of
    the district court is reversed and the case is remanded for
    proceedings consistent with this opinion. Deputy Shelnutt
    may recover his costs in this court.
