    RIPPLE, Circuit Judge. Claude Wiley, Jr. and Tatu M.
    Brown were charged in a single indictment with various
    counts relating to a drug conspiracy. Mr. Brown subse-
    quently entered a conditional guilty plea to a single
    count of conspiracy and the district court sentenced him
    to 188 months’ imprisonment. Mr. Wiley proceeded to
    trial and was convicted of a conspiracy charge and of
    certain distribution charges. The district court sentenced
    him to 395 months’ imprisonment.
    2                                  Nos. 05-2596 & 05-2633
    Mr. Brown and Mr. Wiley timely filed these direct
    appeals. Mr. Brown contends that evidence obtained from
    a search of his home was inadmissible because the affi-
    davit in support of the warrant did not establish probable
    cause. He further submits that the good faith exception to
    the warrant requirement is inapplicable. Mr. Wiley con-
    tends that the jury was instructed improperly as to the
    weight to give the testimony of Government informants
    who received a benefit in exchange for their testimony.
    For the reasons set forth in the following opinion, we
    affirm the convictions of both defendants.
    I
    BACKGROUND
    Mr. Brown and Mr. Wiley were charged in a single, four-
    count superseding indictment with several offenses
    under 
    21 U.S.C. § 841
    (a)(1). Both defendants faced a
    charge of conspiracy to possess with intent to distribute
    and conspiracy to distribute cocaine hydrochloride
    (“powder cocaine”) and cocaine base (“crack”) as well as
    a charge of crack distribution. Mr. Wiley also was charged
    with distribution of powder cocaine. The indictment
    alleged that Mr. Wiley obtained powder cocaine in Chicago
    and that, by himself and with the assistance of others,
    he transported the cocaine to Terre Haute, Indiana,
    where he and Mr. Brown both distributed cocaine powder
    and also manufactured and distributed crack.
    A. Facts and Proceedings Involving Mr. Brown
    1. The Search Warrant
    On January 16, 2003, Drug Enforcement Administration
    (“DEA”) Special Agent Joanna Zoltay executed an eight-
    Nos. 05-2596 & 05-2633                                       3
    page affidavit detailing evidence linking Mr. Brown to
    drug trafficking. This affidavit was intended to accom-
    pany an application for a search warrant for Mr. Brown’s
    residence at 2320 2nd Avenue, Terre Haute, Indiana. In
    that affidavit, Agent Zoltay first recounted facts about a
    controlled buy of cocaine in which Mr. Brown was in-
    volved. Specifically, on September 24, 2002, a confiden-
    tial source (“CS”), whose information previously had
    resulted in over ten convictions of narcotics traffickers,
    contacted the DEA and stated that the CS could pur-
    chase cocaine from a man named Donte Britt.1 The DEA
    prepared the CS for a controlled buy from Britt later
    that same afternoon, including outfitting him with a
    listening device. The CS then traveled to a motel parking
    lot. Britt met the CS at the CS’ vehicle, then walked to a
    green Ford Expedition parked across the street. The CS
    called out over the wire that he observed Mr. Brown in
    the Expedition. A license plate check revealed that the
    Expedition was registered to Annalee Monts, Mr. Brown’s
    girlfriend, at the 2nd Avenue residence. Britt returned
    to the CS’ vehicle from the Expedition carrying 28.9 grams
    of cocaine which the CS purchased and handed over to the
    police. Agent Zoltay further stated that it was consistent
    with her experience in narcotics investigations that “upper
    level narcotics traffickers do not participate in transac-
    tions with persons they do not know, but will deliver to a
    middleman such as Brit[t], who then conducts the trans-
    action.” R.59, Ex.C at 2.
    Agent Zoltay also recounted statements of two additional
    sources who had identified Mr. Brown as a drug trafficker.
    1
    The affidavit refers to him as “Brit,” although the remainder
    of the record makes clear that his name is in fact “Britt.”
    4                                   Nos. 05-2596 & 05-2633
    First, a cooperating individual (“CI-1”), arrested on crack
    distribution charges, had informed the police that he
    had trafficked cocaine for a period of several years and
    that Mr. Brown was his primary drug source during that
    period. He also stated that Mr. Brown supplied other
    distributors, including Britt and Seagrams Poston. CI-1
    told agents that he had witnessed Mr. Brown, on an
    unspecified date, cooking powder cocaine into crack in the
    2nd Avenue residence. CI-1 further stated that he had
    accompanied Mr. Brown when Mr. Brown delivered two
    ounces of crack to a man named Derrick Hatfield in late
    October 2002; Agent Zoltay herself had participated in
    surveillance of Hatfield on October 29, 2002, when Hat-
    field delivered two ounces of crack to a DEA CS. A sec-
    ond cooperating individual (“CI-2”), arrested on cocaine
    trafficking charges, told DEA agents that he had pur-
    chased high-quality marijuana from Mr. Brown.
    Finally, Agent Zoltay’s affidavit provided certain details
    from independent DEA investigations connecting the
    2nd Avenue residence both to Mr. Brown and to drug
    trafficking activity. She stated that, on January 14, 2003,
    DEA agents conducting surveillance on the 2nd Avenue
    residence observed Mr. Brown exit the house to assist
    Monts in carrying groceries from the green Expedition,
    which had been seen at the controlled buy from Britt in
    September 2002. Agents also observed Poston, who had
    a prior conviction for cocaine possession, enter the resi-
    dence with a backpack and leave several hours later
    without it. On January 15, 2003, agents observed Mr.
    Brown exit a car, unlock the front door of the 2nd Avenue
    residence, enter, then later exit, lock the door and return
    to the car. On the same date, Mr. Brown was stopped
    while driving the green Expedition registered to Monts
    Nos. 05-2596 & 05-2633                                   5
    in connection with an investigation relating to a stolen
    Expedition. Also on January 15, 2003, a DEA agent con-
    firmed with a postal inspector that Mr. Brown received
    mail at the 2nd Avenue residence.
    In addition to the specific evidence linking Mr. Brown
    to drug trafficking activity and to the 2nd Avenue resi-
    dence, Agent Zoltay provided additional background
    information drawn from her own experience, including
    the likelihood that certain types of evidence relating
    to drug trafficking activity would be found in the resi-
    dence of a suspected drug trafficker.
    On January 16, 2003, a magistrate judge issued a
    search warrant for the 2nd Avenue home. The officers
    executed the warrant later that same day. The inventory
    from the search included numerous firearms and am-
    munition, a small quantity of marijuana and a marijuana
    pipe, bullet proof vests, a police scanner and Illinois li-
    cense plates. R.59, Ex.B.
    2. Mr. Brown’s Motion to Suppress and the Plea
    Agreement
    Before his trial, Mr. Brown moved to suppress the
    evidence obtained in the search. He challenged the suffi-
    ciency of the affidavit to sustain the magistrate judge’s
    probable cause determination. The district court denied
    the motion and admitted the evidence. In its opinion,
    the district court first addressed the reliability of the
    informants. The court identified CI-1 as the key informant
    and determined that, with respect to this source, suf-
    ficient reliability had been established through corro-
    boration by police investigation and by the statements
    of the other informants. First, the information from CS,
    6                                  Nos. 05-2596 & 05-2633
    whose reliability is established by the statement in the
    affidavit that he had assisted in investigations leading to
    over ten convictions, connected Mr. Brown to Britt, as had
    CI-1. CI-1’s statements regarding deals to Poston were
    corroborated, the court found, however slightly, by the
    observations of the agents at the 2nd Avenue residence,
    who saw Poston enter with the backpack and leave with-
    out it. With respect to Mr. Brown’s sale of cocaine to
    Hatfield, a controlled buy by a DEA source from Hat-
    field corresponded to the date and drug quantity identi-
    fied by CI-1. The district court concluded that, taken
    together, these statements tended to establish as reliable
    the information that CI-1 had purchased cocaine from
    Mr. Brown and had observed Mr. Brown cooking cocaine
    in the searched residence. Moreover, reasoned the court,
    the statements of CI-1 should be credited because they
    were offered against CI-1’s penal interest. The court
    thus concluded that the DEA had corroborated suffi-
    ciently CI-1’s statements through investigation. It further
    determined that, based on the totality of circumstances,
    the magistrate judge had a substantial basis for conclud-
    ing that the affidavit contained probable cause to sup-
    port a finding that Mr. Brown was a drug trafficker.
    The court also found that the reliability of CS was
    supported not only by the agent’s direct statement in the
    affidavit, but also because the CS’ statements placing
    Mr. Brown in the Expedition at the time of the controlled
    buy from Britt in 2002 were corroborated by an independ-
    ent investigation connecting Mr. Brown and the Expedi-
    tion.
    Turning to the question of nexus between the alleged
    criminal activity and the premises, the district court
    concluded that the requisite connection was established by
    Nos. 05-2596 & 05-2633                                      7
    the nature of the criminal activity at issue and the prob-
    ability that evidence of drug dealing may be found where
    drug dealers live. R.71 at 13 (citing United States v. Lamon,
    
    930 F.2d 1183
    , 1188 (7th Cir. 1991)). More specifically,
    the court concluded that the affidavit sufficiently linked
    Mr. Brown himself to the 2nd Avenue home. The most
    critical evidence, in the court’s view, was Mr. Brown’s
    possession of a key to the house, suggesting some ele-
    ment of dominion and control over the location. In addi-
    tion, he was observed carrying in groceries, and he ap-
    parently had received mail at the residence. Refusing to
    accept as a general proposition that a drug dealer’s home
    categorically establishes the nexus to criminal activity
    required to support a warrant, the court found further
    evidence connecting Mr. Brown’s criminal activities to the
    home was sufficient to establish the requisite nexus.
    Specifically, CI-1 had stated that he had observed Mr.
    Brown cooking cocaine into crack at the residence.
    The court then turned to the case authorities relied upon
    by Mr. Brown in support of his lack-of-nexus argument.
    In the court’s view, those cases involved substantially
    thinner connections to the home. Specifically, Mr. Brown
    had contended that his case was substantially similar
    to two cases in which a court had concluded that a
    nexus to the searched premises was lacking. However, as
    the district court noted, in one of those cases the only
    connection was a vehicle registration; in another, there
    was simply a conclusory statement that a defendant
    resided at the place to be searched. R.71 at 14-16 (citing
    United States v. McNeal, 
    82 F. Supp.2d 945
    , 957-60 (S.D. Ind.
    2000), and United States v. Dickerson, 
    975 F.2d 1245
     (7th Cir.
    1992)). In neither case, concluded the court, did the war-
    rant include specific statements regarding the defendant’s
    8                                     Nos. 05-2596 & 05-2633
    entry or exit from the house, possession of a key, receipt of
    mail, or illegal activity within the house. Given these
    facts, and the court’s belief that there was a certain inher-
    ent likelihood that evidence of drug activity would be
    found in a drug dealer’s home, the court held that there
    was a substantial basis for probable cause linking the home
    with Mr. Brown’s illegal activities.
    The district court then turned to Mr. Brown’s final
    argument that the information provided in the affidavit
    was stale at the time that it was presented to the magistrate
    judge. The court concluded that, even though some of the
    evidence was from several months prior to the applica-
    tion, it nevertheless established a pattern of on-going
    criminal activity. In such circumstances, the court con-
    cluded, “the passage of time becomes less critical,” and
    staleness less of a concern in establishing probable cause.
    R.71 at 17 (citing Lamon, 
    930 F.2d at 1188
    ). In sum, al-
    though calling it a “close case,” the district court deter-
    mined that the warrant should be upheld as supported by
    probable cause. R.71 at 17.
    Turning to the issue of good faith reliance, the district
    court concluded that, even if the affidavit were insuffi-
    cient to establish probable cause, it was not so lacking as
    to render belief by the executing officers in the existence
    of probable cause “entirely unreasonable.” Id. at 18 (quot-
    ing United States v. Koerth, 
    312 F.3d 862
    , 868 (7th Cir. 2002)).
    Therefore, the court held in the alternative that the
    good faith exception was applicable.
    Having determined, on alternate grounds, that the
    search did not violate the Fourth Amendment, the court
    denied the motion to suppress.
    Following this ruling, Mr. Brown pleaded guilty to,
    and was sentenced on, the conspiracy count only, but
    Nos. 05-2596 & 05-2633                                    9
    conditioned his plea on his right to appeal the sup-
    pression issue.
    B. Proceedings Involving Mr. Wiley
    1. Investigation
    In 2003, the Vigo County Drug Task Force suspected
    Mr. Wiley of dealing drugs in the Terre Haute area. At the
    about the same time, Timothy Bailey was arrested and
    charged with certain methamphetamine and marijuana
    offenses in Vigo County. As a part of a deal struck with
    the prosecutor’s office, Bailey agreed to cooperate as an
    informant to the Drug Task Force on Mr. Wiley’s drug
    trafficking activities. Bailey also agreed to participate in
    a controlled buy of powder cocaine from Mr. Wiley for
    the Task Force.
    On the morning of August 21, 2003, Bailey arranged a
    meeting with Mr. Wiley to purchase four-and-a-half
    ounces of powder cocaine for $3000 later that day. Detec-
    tive Charles Burress of the Terre Haute City Police pre-
    pared Bailey for the buy. He strip-searched Bailey and
    also searched his vehicle prior to the actual purchase,
    proceeded to a location to view Mr. Wiley’s residence
    and observed Bailey enter the residence with money
    provided by law enforcement to purchase cocaine. Bailey
    testified that he requested the cocaine from Mr. Wiley
    and waited with Mr. Brown for some time, smoking
    marijuana in the kitchen, while Mr. Wiley and his cousin
    finished playing a video game. R.71 at 211. According to
    Bailey, Mr. Brown left sometime before Bailey. 
    Id.
     Bailey
    then left the house forty-five minutes to an hour later and
    proceeded to a drop location to meet with Detective
    Burress and provide to him what was later determined
    10                                Nos. 05-2596 & 05-2633
    to be 121 grams of cocaine. Bailey said that he had pur-
    chased this cocaine from Mr. Wiley.
    Agents conducted surveillance on Mr. Wiley’s residence
    both before and during the buy and remained there after
    Bailey left while a search warrant was obtained. Mr. Wiley
    left the residence during this period; agents on the
    scene asked that a marked police car conduct a traffic
    stop of the car he was traveling in and detain him. The
    agents obtained the warrant later that afternoon and
    searched his home where they discovered crack in the
    kitchen freezer and other drug paraphernalia.
    2. The Trial and the Jury Instruction
    At trial, Detective Burress and Bailey testified about
    the controlled buy leading to the search of Mr. Wiley’s
    home. Bailey also testified that he had obtained small
    amounts of powder cocaine from Mr. Brown for several
    years during the 1990s in Terre Haute and that, from
    1994 until 2001, when he was arrested, he had purchased
    large amounts of cocaine from Mr. Wiley and Mr. Brown.
    The Government also called Michael Collier as a wit-
    ness. He testified that he had purchased crack from
    Mr. Brown for several years and that during that time, he
    came to know Mr. Wiley as “Cuz,” Mr. Brown’s cocaine
    source. Collier testified that he previously had shuttled
    cocaine from Mr. Wiley in Chicago to Mr. Brown in Terre
    Haute. He also stated that he had traveled with Mr. Brown
    to Chicago on another occasion. While in Chicago,
    Mr. Brown had seen Mr. Wiley, among others, and, on
    returning to Terre Haute, Mr. Brown had cocaine that he
    had not possessed earlier. Collier told the jury that, in
    exchange for his testimony, the Government had agreed
    Nos. 05-2596 & 05-2633                                     11
    not to file an information alleging a prior felony drug
    conviction. Consequently, Collier avoided the possibility
    of a sentencing enhancement based on that prior convic-
    tion in his future trial on federal cocaine charges. Because
    of this agreement, his minimum sentence would be ten,
    not twenty, years.
    At the conclusion of a two-day trial, the court instructed
    the jury. Included among the instructions was the follow-
    ing cautionary instruction pertaining to informant credibil-
    ity:
    You have heard testimony from several witnesses who:
    (1) received a benefit from the [G]overnment in
    connection with this case, namely a promise of a
    recommendation for a reduced sentence;
    (2) stated that they were involved in the commis-
    sion of the offenses as charged against the Defen-
    dants; and
    (3) have pleaded guilty to an offense arising out of
    the same occurrence for which the Defendants are
    now on trial. Their admission of guilt is not to be
    considered as evidence against the Defendants on
    trial.
    You may give the testimony of such witnesses
    the weight as you feel it deserves, keeping in mind
    that it is to be received with caution and weighed
    with great care.
    R.75 at 322. The jury returned a verdict of guilty on a lesser
    included conspiracy charge and on distribution charges
    for both powder cocaine and cocaine base. The district
    court sentenced Mr. Wiley to 395 months’ imprisonment.

    DISCUSSION
    A. Mr. Brown’s Motion to Suppress
    Mr. Brown asks that we review the ruling of the district
    court denying his motion to suppress the evidence ob-
    tained in the search of his home. Whether a warrant
    affidavit includes sufficient indicia of probable cause is a
    legal conclusion that we review de novo. United States v.
    Harris, 
    464 F.3d 733
    , 738 (7th Cir. 2006).
    We have stated:
    A magistrate’s determination of probable cause is to
    be given considerable weight and should be over-
    ruled only when the supporting affidavit, read as a
    whole in a realistic and common sense manner, does
    not allege specific facts and circumstances from which
    the magistrate could reasonably conclude that the
    items sought to be seized are associated with the
    crime and located in the place indicated.
    United States v. Newsom, 
    402 F.3d 780
    , 782 (7th Cir. 2005)
    (internal citation and quotation marks omitted). The
    probable cause inquiry “is practical, not technical, and
    we consider the totality of the circumstances.” United
    States v. Anderson, 
    450 F.3d 294
    , 302 (7th Cir. 2006) (internal
    citations and quotation marks omitted). However, where
    “an affidavit is all that was presented to the issuing
    judge, the warrant’s validity rests on the strength of the
    affidavit.” 
    Id.
     When an affidavit is based on informant tips,
    our probable cause inquiry is also based on the totality of
    the circumstances. See Illinois v. Gates, 
    462 U.S. 213
    , 230
    (1983). However, four factors are particularly relevant as
    a part of this inquiry. Specifically, we shall pay close at-
    Nos. 05-2596 & 05-2633                                     13
    tention to: “(1) the extent to which the police have corrobo-
    rated the informant’s statements; (2) the degree to which
    the informant has acquired knowledge of the events
    through firsthand observation; (3) the amount of detail
    provided; and (4) the interval between the date of the
    events and police officer’s application for the search
    warrant.” United States v. Koerth, 
    312 F.3d 862
    , 866 (7th Cir.
    2002).
    Mr. Brown contends that various omissions demon-
    strate the absence of probable cause. First, Mr. Brown notes
    that the affidavit fails to establish the credibility of the
    informants on which it relies, particularly CI-1 and CI-2.
    With respect to the information provided by CI-1,
    Mr. Brown argues that the account does not provide a date
    on material facts, such as the observation of Mr. Brown
    cooking cocaine. Accordingly, he submits, the facts could
    be so stale that, at the time the warrant was obtained,
    probable cause no longer existed. With respect to CI-2,
    Mr. Brown notes that the affidavit does not provide any
    evidence of a link to the residence to be searched.
    Mr. Brown’s argument seeks to separate each assertion
    in the affidavit and to find an infirmity with all of them.
    The flaw in Mr. Brown’s approach is its failure to recognize
    the nature of the probable cause inquiry: We, like the
    issuing magistrate judge, assess the totality of circum-
    stances presented and make a practical, common-sense
    determination about the existence of probable cause on
    the basis of the affidavit as a whole. Credibility of infor-
    mants, nexus to the searched premises and to illegal
    activity, and the age of the information are all relevant
    considerations in this inquiry, but no single piece of
    information need satisfy every relevant consideration
    14                                     Nos. 05-2596 & 05-2633
    before we may consider it.2 When specific facts and
    circumstances are alleged that reasonably could lead a
    magistrate judge to believe that the fruits or instrument-
    alities of a crime are to be found at a particular location,
    we shall give great weight to that determination. See
    Newsom, 
    402 F.3d at 782
    .
    We now turn to an examination of the facts relevant
    in assessing the existence of probable cause in the affidavit
    at issue. Three separate informants provided informa-
    tion linking Mr. Brown to drug activity; all claimed first-
    hand knowledge of Mr. Brown’s drug activities. CS was a
    source from which the DEA agent preparing the affidavit
    previously had received reliable information. CI-1’s
    information overlapped to some degree with CS’ infor-
    mation, insofar as it linked Mr. Brown to Britt, the
    controlled-buy target of CS and the DEA. CI-1’s informa-
    tion regarding Mr. Brown’s residence was corroborated
    by the independent investigation that revealed his free
    entry and exit from the home during the relevant period.
    CI-1’s information regarding Mr. Brown’s drug activ-
    ities was corroborated by the information about the
    separate controlled buy from Hatfield; CI-1 stated that he
    and Mr. Brown had provided the original cocaine for that
    transaction. CI-2’s information admittedly adds little
    insofar as it relates to an entirely different drug and
    2
    This is not a case where the defendant alleges that the affi-
    davit included false information (or material omissions) that
    must be excised (or must be added) before the determination of
    probable cause is made. See United States v. Merritt, 
    361 F.3d 1005
    , 1010 (7th Cir. 2004), vacated and remanded in light of
    United States v. Booker, 
    543 U.S. 220
     (2005); see generally Franks
    v. Delaware, 
    438 U.S. 154
     (1978).
    Nos. 05-2596 & 05-2633                                    15
    points to no specific occurrences tending to corroborate
    anything the other informants had stated other than the
    general proposition that Mr. Brown trafficked in narcotics.
    Considering the totality of the circumstances described
    in the affidavit, we conclude that the district court was
    correct in its ruling that the magistrate judge had a sub-
    stantial basis for concluding that probable cause existed.
    We are not persuaded by Mr. Brown’s contentions to the
    contrary. We acknowledge that the affidavit does not
    provide any statements attesting to the credibility of
    either CI-1 or CI-2 and that, in fact, the information con-
    tained in the warrant about the individuals (that they
    were cooperating with law enforcement following their
    own arrests) does not strongly suggest that their ac-
    counts are unimpeachable. Nonetheless, CI-1’s statement,
    which provides the most material details, is corroborated
    generally by CS’ and CI-2’s identification of Mr. Brown as
    a narcotics trafficker. CI-1’s identification of Mr. Brown
    with cocaine trafficking specifically and his connection to
    Britt are both items which are corroborated by CS’ state-
    ment. On perhaps the affidavit’s most convincing and
    most damaging facts, as far as Mr. Brown is concerned,
    further corroboration was provided by independent
    investigation, such as the controlled buys from Britt and
    Hatfield, which add “great weight” to the reliability of an
    informant’s tip. United States v. McKinney, 
    143 F.3d 325
    , 329
    (7th Cir. 1998). In addition, under the facts and circum-
    stances presented here, staleness does not greatly limit
    the information presented because the information pos-
    sessed by the DEA indicated an on-going pattern of
    criminal activity. United States v. Lamon, 
    930 F.2d 1183
    ,
    1187-88 (7th Cir. 1991).
    Finally, on the issue of nexus, “[p]robable cause does
    not require direct evidence linking a crime to a particular
    16                                  Nos. 05-2596 & 05-2633
    place. Instead, issuing judges are entitled to draw rea-
    sonable inferences about where evidence is likely to be
    found given the nature of the evidence and the type of
    offense. In the case of drug dealers, evidence is often found
    at their residences.” Anderson, 
    450 F.3d at 303
     (internal
    quotation marks and citations omitted). We agree with
    the district court that it would be inappropriate to adopt
    a categorical rule that would, in every case, uphold a
    finding of probable cause to search a particular location
    simply because a suspected drug trafficker resides there;
    we nevertheless conclude that, in this case, a belief that a
    sufficient nexus exists is supported by the affidavit itself.
    Specifically, Agent Zoltay states that CI-1 observed
    Mr. Brown cook cocaine into crack and that Poston, who
    CI-1 identifies as another narcotics trafficker linked to
    Mr. Brown, was observed by police entering the residence
    and leaving a bag inside. These statements directly con-
    nect the residence to Mr. Brown’s trafficking activities. In
    consideration of the totality of circumstances presented
    to the magistrate judge and given the practical nature of
    the probable cause determination, we conclude that the
    magistrate judge had a substantial basis to find probable
    cause for the warrant to issue.
    Even if probable cause was lacking, we still would not
    exclude the evidence obtained unless Mr. Brown also
    demonstrated that the officer could not reasonably have
    believed that the facts set forth in the affidavit were
    sufficient to support the magistrate judge’s determina-
    tion of probable cause. Koerth, 312 F.3d at 866 (citing
    United States v. Leon, 
    468 U.S. 897
     (1984)).
    We review de novo the district court’s conclusion that
    law enforcement officers reasonably relied on a search
    warrant that is subsequently invalidated. United States v.
    Sidwell, 
    440 F.3d 865
    , 869 (7th Cir. 2006). The decision to
    Nos. 05-2596 & 05-2633                                   17
    seek a warrant is prima facie evidence that an officer
    was acting in good faith. Koerth, 312 F.3d at 868. The
    defendant must defeat this presumption with evidence
    that the issuing magistrate judge wholly abandoned his
    judicial role or that the officer’s affidavit was so lacking
    in indicia of probable cause as to render official belief in
    its existence entirely unreasonable. Id.
    Mr. Brown’s argument on this point is relatively thin,
    and makes broad generalizations that “no facts” corrobo-
    rate informant information, that “no facts” establish that
    Mr. Brown lived at the residence, and that “no nexus” was
    made between Brown’s dealing and the residence. Appel-
    lants’ Br. at 24. These statements are not supported by
    the record. Although corroboration of some elements of
    the informants’ statements is lacking, independent
    police corroboration was a significant factor in establish-
    ing the reliability of the informants. Likewise, some
    evidence, specifically Mr. Brown’s possession of a key and
    the statement of the postal inspector, established Mr.
    Brown’s residence, and statements from CI-1 connected
    the residence to the drug dealing activity. Accordingly,
    even if the warrant itself were infirm, Mr. Brown has not
    made substantial arguments that the good faith exception
    should not apply. Therefore, the evidence is admissible,
    and we affirm Mr. Brown’s conviction and sentence.
    B. The Cautionary Instruction at Mr. Wiley’s Trial
    Mr. Wiley asks that we review the language of the
    cautionary instruction. At the outset, we note that Mr.
    Wiley failed to object to this instruction at trial and,
    therefore, he has forfeited this argument. Forfeited objec-
    tions to jury instructions are reviewed for plain error.
    United States v. Holmes, 
    93 F.3d 289
    , 292 (7th Cir. 1996).
    18                                        Nos. 05-2596 & 05-2633
    “[E]rror is plain, first of all, if it is clearly an error . . . . But
    it must also affect the defendant’s substantial rights and,
    in addition, seriously affect the fairness, integrity, or
    public reputation of judicial proceedings.” United States
    v. Paladino, 
    401 F.3d 471
    , 481 (7th Cir. 2005) (internal
    quotation marks and citations omitted). It must be “so
    obvious, crucial, and egregious that we may and should
    correct it even though no objection was made below.”
    Backwater, Inc. v. Penn-American Ins. Co., 
    448 F.3d 962
    , 965
    (7th Cir. 2006).
    The Supreme Court has stated that informant testi-
    mony presents special credibility problems, and accord-
    ingly, careful instructions to the jury regarding credibil-
    ity are appropriate. Banks v. Dretke, 
    540 U.S. 668
    , 701-02
    (2004); see also On Lee v. United States, 
    343 U.S. 747
    , 757
    (1952) (“The use of informers, accessories, accomplices,
    false friends, or any of the other betrayals which are ‘dirty
    business’ may raise serious questions of credibility. To
    the extent that they do, a defendant is entitled to broad
    latitude to probe credibility by cross-examination and
    to have the issues submitted to the jury with careful
    instructions.”).
    In considering the matter of instructions regarding
    informant credibility, this court has held that a special
    instruction is not necessary as a matter of course and that,
    as a general matter, a general credibility instruction
    will suffice. United States v. Cook, 
    102 F.3d 249
    , 252-53 (7th
    Cir. 1996). Moreover, we have emphasized that the dis-
    trict court is “best situated to detect and deal with threats
    of unreliable testimony,” 
    id. at 252
    , and therefore to
    determine when such an instruction is advisable or neces-
    sary.
    Mr. Wiley does not dispute the state of this circuit’s law.
    Nor does he dispute that our review is limited to plain
    Nos. 05-2596 & 05-2633                                    19
    error because he failed to object at trial. He nonetheless
    challenges the instruction given by the district court. He
    contends essentially that the instruction was so ill-tailored
    to the actual facts of the case that the jury reasonably
    might not have understood to whom it was directed.
    Mr. Wiley argues that reversal is required because, by
    virtue of giving an instruction that is not required by this
    circuit’s precedent, the district court clearly signaled that
    it believed the testimony of the informant witnesses
    posed a special danger to the fairness of the trial and that
    a supplementary instruction was necessary under
    the circumstances. Appellants’ Br. at 12-13. Mr. Wiley
    bolsters his contention by pointing to record facts he
    believes demonstrate reason for particular apprehension
    regarding the informant testimony in this case, includ-
    ing a lack of a recording of the controlled buy from Bailey
    and the absence of visual contact by investigators dur-
    ing the buy.
    The instruction actually provided at trial refers gen-
    erally to “witnesses who received a benefit from the
    government,” and identifies that benefit as the promise of
    a reduced sentence. R.75 at 322. The instruction also
    states that these witnesses were involved in and pleaded
    guilty to an offense arising out of the same occurrence
    for which the defendants are on trial. The problem with
    this instruction, in Mr. Wiley’s view, is that it deviates
    from the pattern instruction in failing to name specifically
    the witnesses to whom it should apply and that, on its
    facts, it cannot be applied to the informants involved in
    this case.
    Although the instruction that was given was ill-tailored
    to the facts of his case, we are persuaded that any error
    was harmless under the circumstances.
    20                                  Nos. 05-2596 & 05-2633
    The informant-witnesses in this case are Bailey and
    Collier. While the statements of each implicated them-
    selves in the drug trade and in some involvement with
    Mr. Wiley in that regard, neither was involved directly
    in any occurrence for which Mr. Wiley currently stood
    trial and neither pleaded guilty to any conduct arising
    out of the conspiracy with which Mr. Wiley was charged.
    Bailey received a reduced sentence in state court in ex-
    change for his cooperation with the investigation and
    prosecution of Mr. Wiley; Collier did not receive a sentence
    reduction, as stated in the instruction, but was the benefi-
    ciary of a decision not to seek an enhancement of his sen-
    tence on the basis of a prior felony drug conviction.
    Mr. Wiley’s argument first presupposes that, in the
    course of this relatively short trial with relatively few
    witnesses, the jury would have misunderstood to whom
    this instruction was meant to apply. He apparently be-
    lieves that a detailed parsing of the instruction would
    have confused the jury to such an extent that it would
    not have applied its cautions to either Bailey or Collier.
    We cannot accept Mr. Wiley’s suggestion of the prob-
    able impact of the instruction. We further note that, even
    if the jury had concluded that the instruction did not
    apply to the informant-witnesses, the ultimate effect
    would simply be that the general instruction on credibil-
    ity, which asked the jury to consider witnesses’ poten-
    tial bias and prejudice in determining the weight to give
    their testimony, would be left to carry the day. It is our
    duty to consider whether the instructions in their entirety
    may have prejudiced the defendant by confusing or
    misleading the jury, see United States v. White, 
    443 F.3d 582
    , 587-88 (7th Cir. 2006), but Mr. Wiley’s argument
    suggests only the remote possibility that the jury could
    Nos. 05-2596 & 05-2633                                     21
    have been misled into thinking that the specific informant
    instruction did not apply to any witness. If true, that leaves
    him in precisely the position this circuit’s precedent allows:
    no special instruction on informant credibility.
    In addition, both informants admitted the benefits they
    received during their testimony. In closing arguments,
    Mr. Wiley’s counsel separately drew attention to the
    particular credibility problem posed by informant testi-
    mony. These methods of informing the jury about the
    dangers of such testimony are specifically approved of by
    this court as generally providing adequate protection for a
    defendant facing informant witnesses. See Cook, 
    102 F.3d at 251
     (“[T]he argument against giving [a special] instruc-
    tion is . . . straightforward: the informant’s motive can be
    spelled out by counsel (if it is not admitted on cross-
    examination) and considered under the general credibil-
    ity instruction.”).
    As noted above, we review the instruction to the jury
    in its entirety. United States v. Renner, 
    238 F.3d 810
    , 812-13
    (7th Cir. 2001). Although we conclude that the instruction
    was not tailored properly to the facts of the case and
    failed to identify specifically the witnesses to whom it
    applied, the fact that the general credibility instruction
    was given, combined with the absence of any peculiar
    facts that would indicate the necessity of a special instruc-
    tion, renders any error harmless.
    Conclusion
    For the foregoing reasons, the convictions of both de-
    fendants are affirmed.
    AFFIRMED
    22                                   Nos. 05-2596 & 05-2633
    WILLIAMS, Circuit Judge, concurring. Like my col-
    leagues, I think “it would be inappropriate to adopt a
    categorical rule that would, in every case, uphold a find-
    ing of probable cause to search a particular location
    simply because a suspected drug trafficker resides there.”
    Op. at 16. I write separately, however, because I fear
    the majority has come dangerously close to doing exactly
    that.
    Probable cause amounts to a showing “(1) that it is now
    probable that (2) contraband, evidence of a crime, or a
    fugitive will be on the described premises (3) when the
    warrant is executed.” United States v. Grubbs, 
    126 S. Ct. 1494
    , 1500 (2006); see Illinois v. Gates, 
    462 U.S. 213
    , 238
    (1983). The majority concludes that CI-1’s undated ac-
    count of seeing Brown cook crack at the residence and law
    enforcement’s observation of Poston, an alleged cocaine
    trafficker, entering the home and leaving behind a back-
    pack, establish a nexus between drug trafficking and the
    premises, thereby sidestepping an ill-advised categorical
    rule. I cannot be so sure.
    In my view, that CI-1 witnessed Brown cook crack at the
    residence at an unspecified time is of little probative value.
    The warrant affidavit gives no indication whatsoever as
    to when Brown was observed cooking crack. And, “[i]n
    determining whether probable cause exists, magistrates
    should consider, as one factor, the age of the information
    in the supporting affidavit.” United States v. Lamon, 
    930 F.2d 1183
    , 1187-88 (7th Cir. 1991) (citing United States v.
    Batchelder, 
    824 F.2d 563
    , 564 (7th Cir. 1987)). Because CI-1’s
    single observation might have been several years old, it
    could hardly predict whether contraband would be
    found on the premises on the day of the search. Admit-
    tedly, as the majority notes, where an ongoing pattern of
    Nos. 05-2596 & 05-2633                                      23
    criminal activity is involved, staleness is less of a concern.
    But, even where ongoing criminal activity is at issue, at
    some point an event becomes too old to have meaningful
    predictive value. Given the total lack of information
    regarding the date of CI-1’s observation, we have no way
    of discerning whether that threshold has been reached
    here.
    Nor does the additional fact that an alleged cocaine
    trafficker set foot in the home and left behind a backpack
    get the government over the probable cause hurdle. The
    officers knew nothing of the backpack’s contents or even
    whether it was purposefully left behind. And, given the
    three-hour duration of Poston’s stay, it is as likely that
    he entered the home for a social call as for a drug trans-
    action. In this way, any suspicions regarding the purpose
    of Poston’s visit were just that—suspicions—and where
    probable cause is concerned, “mere suspicion is not
    enough.” United States v. Ingrao, 
    897 F.2d 860
    , 862 (7th Cir.
    1990). On this record, then, I do not think it can be said
    that officers were likely to find evidence of drug dealing
    at Brown’s home at the time of the search. (And, notably,
    no cocaine, large sums of money, or drug-transaction
    records were found during the search.)
    In the end, the affidavit did little more than establish that
    Brown resided at the home and had probably trafficked
    in crack cocaine outside of his home. Because I am not
    prepared to conclude that police officers always have
    probable cause to search the residence of a suspected drug
    trafficker, I would affirm Brown’s conviction not by
    concluding that there was probable cause for the
    search, but because the police acted in good faith.
