State v. Meyer

N. PATRICK CROOKS, J.

¶ 1. The State of Wisconsin (State) seeks review of an unpublished decision of the court of appeals¹ reversing the conviction of Tory M. Meyer (Meyer) for possession of tetrahydro-cannabinols (THC) with the intent to deliver, as a party to a crime, contrary to Wis. Stat. §§ 939.05 and 161.41(lm)(h)2.² The Sheboygan County Circuit Court, Honorable Gary Langhoff presiding, denied Meyer's motion to suppress evidence seized during the execution of an anticipatory search warrant.³ The circuit court also determined that the officers' act of dispensing with the rule of announcement in executing the warrant was reasonable. Meyer was convicted of possession of THC with the intent to deliver, as a party to a crime. On appeal the court of appeals reversed the circuit court's judgment and remanded the case, concluding the no-knock entry during the execution of the search warrant was in violation of Meyer's rights under the Fourth Amendment to the United States Constitution.

¶ 2. We conclude that the anticipatory search warrant is constitutional because it is supported by probable cause. We further conclude that the warrant is not unconstitutional merely because it lacks explicit conditional language stating that the warrant may not be executed until delivery of the contraband is made to the premises to be searched. Finally, we conclude that under Richards v. Wisconsin, 520 U.S. —, 117 S. Ct. 1416 (1997), an officer may dispense with the rule of announcement⁴ when executing a search warrant if the officer has a reasonable suspicion, based upon the particular facts of a given case and the reasonable inferences drawn therefrom, that knocking and announcing the officer's presence would be dangerous or futile or inhibit the effective investigation of the crime. Furthermore, in determining whether reasonable suspicion exists, an officer's training and prior experience in similar situations may be considered in combination with the particular facts. Accordingly, we remand the case to the circuit court for a determination whether, in consideration of the particular facts presented in this case, the officers had a reasonable suspicion that exigent circumstances existed to justify their no-knock entry.

I.

¶ 3. The facts are undisputed for purposes of our review. On November 17, 1995, Sheboygan County Sheriffs Detective Alonna Koenig (Koenig) applied for a warrant to search the premises located at 1033 St. Clair Avenue in the city of Sheboygan. In the affidavit supporting the warrant, Koenig stated the following:

¶ 4. Koenig had received information from United States Postal Inspector Dan Kakonis (Kakonis) regarding a package Kakonis had intercepted which he believed to contain controlled substances. Kakonis, who had eight years of experience working as a postal inspector, had worked with Koenig on prior occasions and provided her information which subsequently led to the interception of packages containing controlled substances and related paraphernalia. Pursuant to his training and personal experience, Kakonis had informed Koenig that packages containing controlled substances often contain handwritten labels, incorrect or fictitious names or addresses, a perfumed odor to disguise any pungent odor from the controlled substance, that such packages are often sent via Express Mail, and that the source of the packages is often a state from which controlled substances are generally shipped, such as California.

¶ 5. Koenig further stated that on November 16, 1995, at the Post Office in Milwaukee, Wisconsin, Kakonis profiled a package being sent Express Mail to a Tory "Mayor" at 1033 St. Clair Avenue, Sheboygan, Wisconsin. A mail carrier for that route informed Kakonis that there was an individual by the name of Tory Meyer residing at 1033 St. Clair Avenue. The return address indicated the package was en route from California. Kakonis intercepted the package and brought it to the Sheboygan County Sheriffs Department. On November 17, 1995, a K-9 Unit.(i.e., canine) from the Sheboygan County Sheriff s drug unit located the package from among other similar shaped and sized packages by scratching and biting at the package, indicating that the trained dog detected controlled substances in the package. Based upon this information, Koenig stated she believed that there would be "illegal controlled substances" located at 1033 St. Clair Avenue in Sheboygan, including cocaine and/or marijuana, and possibly related drug paraphernalia, including identifiers, drug ledgers, packaging materials, scales, and items used to ingest drugs.

¶ 6. Sheboygan County Circuit Court Commissioner Terence T. Bourke issued a search warrant at 1:30 p.m. on November 17, 1995, finding probable cause to believe that there were controlled substances "now located and concealed in and upon" the premises occupied by Tory Meyer at 1033 St. Clair Avenue, She-boygan. The warrant authorized a search for controlled substances, drug ledgers or records, packaging materials, identifiers, scales, and items used for the consumption of illegal drugs.

¶ 7. Koenig delivered the intercepted package to an individual identifying himself as Tory Meyer at 1033 St. Clair Avenue on November 17, 1995, at approximately 2:20 p.m. Ten minutes later the drug enforcement unit executed the search warrant. The police knocked on the door and then broke the door in with a battering ram. The officers announced their presence while crossing the threshold of the premises. The officers searched the premisés and found marijuana and other drug-related paraphernalia. As a result of the evidence seized, the State charged Meyer with possession of THC with the intent to deliver, as a party to a crime, contrary to Wis. Stat. §§ 939.05 and 161.41(lm)(h)2, and possession of a Schedule I⁵ controlled substance without a tax stamp, as a party to a crime, contrary to Wis. Stat. §§ 939.05 and 139.95(1) and (2).

¶ 8. Meyer brought a motion to suppress the evidence seized during the execution of the warrant, asserting violations of his rights as guaranteed under the Fourth Amendment to the United States Constitution⁶ and Article I, § 11 of the Wisconsin Constitution.⁷ First, Meyer argued that the warrant was an unconstitutional anticipatory or conditional warrant as it was not supported by probable cause. Second, Meyer argued that the police entry was unconstitutional because the police did not knock and announce , their presence, and that there was no probable cause for the police to dispense with the knock and announce requirement. Third, Meyer argued that the detention of his mail was illegal and, therefore, the search warrant based upon that detention was illegal.⁸

¶ 9. The circuit court denied Meyer's motion to suppress. The circuit court found that the postal inspector had a reasonable suspicion to detain the package and that the length of detention under the circumstances was reasonable. The court also found that there was a substantial basis for determining that probable cause existed to issue the search warrant. The circuit court determined that the warrant was not "technically an anticipatory search warrant," and did not specifically address Meyer's assertion that the warrant lacked the requisite conditional language. However, without correction from the court, defense counsel clarified his understanding that the circuit court was denying Meyer's argument that the lack of conditional language rendered the warrant unconstitutional. The circuit court further determined that the police were justified in making the no-knock entry.

¶ 10. Pursuant to a negotiated plea agreement Meyer agreed to plead no contest to the charge of possession of THC with intent to deliver, as a party to a crime, and the State agreed to move to dismiss the charge of possessing controlled substances without a tax stamp, as a party to a crime. Based on this plea, the circuit court found Meyer guilty of possession of THC with the intent to deliver, as a party to a crime, contrary to Wis. Stat. §§ 939.05 and 161.41(lm)(h)2. Meyer appealed.

¶ 11. The court of appeals reversed the judgment of the circuit court and remanded the case. The court of appeals' recognized that the "blanket rule," allowing officers to dispense with the rule of announcement in cases involving felony drug investigations, set forth by this court in State v. Stevens⁹ and reaffirmed in State v. Richards (.Richards I)¹⁰ had been rejected by the United States Supreme Court in Richards v. Wisconsin (Richards II).¹¹ The court of appeals concluded that the execution of the search warrant was in violation of Meyer's rights under the Fourth Amendment to the United States Constitution pursuant to Richards II. The court of appeals rejected the State's reliance on Segura v. United States, 468 U.S. 796 (1984) to support its argument that regardless of the constitutionality of the entry, the evidence need not be suppressed because it was obtained in accordance with a valid search warrant issued by a neutral and detached commissioner. The court distinguished Segura, noting that the disposition in Segura was "carefully limited" to the facts presented in that case. The court of appeals also rejected the State's argument that the court should adopt a good faith exception to the exclusionary rule¹² in this instance. The court of appeals declined the invitation, stating that it "is a function of our supreme court" to adopt an exception to the exclusionary rule.¹³

II.

¶ 12. Before addressing the State s assertion that the no-knock entry was constitutional, we first consider Meyer's arguments that the warrant is unconstitutional because it (1) is not supported by probable cause; and (2) does not contain sufficient conditional language as is required in an anticipatory search warrant. We address each of Meyer's objections to the warrant in turn.

A.

¶ 13. Anticipatory warrants are not unconstitutional per se. See State v. Falbo, 190 Wis. 2d 328, 335, 526 N.W.2d 814 (Ct. App. 1994) (citing United States v. Garcia, 882 F.2d 699, 702 (2d Cir. 1989)); United States v. Leidner, 99 F.3d 1423, 1426 (7th Cir. 1996), cert. denied, — U.S. —, 117 S. Ct. 1434 (1997); 2 Wayne R. LaFave, Search and Seizure § 3.7(c), at 364 (3d ed. 1996). Although an anticipatory warrant is "issued before the necessary events have occurred which will allow a constitutional search of the premises," such search warrants must still be based upon probable cause. Garcia, 882 F.2d at 702.

¶ 14. In reviewing whether probable cause exists to issue a search warrant, we give great deference to the warrant-issuing commissioner.¹⁴ See State v. Kerr, 181 Wis. 2d 372, 379, 511 N.W.2d 586 (1994). As such, we are confined to the record as it existed before the commissioner and must consider whether he or she was " 'apprised of sufficient facts to excite an honest belief in a reasonable mind that the objects sought are linked with the commission of a crime, and that they will be found in the place to be searched.'" Id. at 378 (quoting State v. Starke, 81 Wis. 2d 399, 408, 260 N.W.2d 739 (1978)). The commissioner's decision to issue a warrant will be upheld unless the facts before the commissioner at the time the warrant was issued were " 'clearly insufficient to support a finding of probable cause.'" Kerr, 181 Wis. 2d at 380 (quoting State v. Higginbotham, 162 Wis. 2d 978, 989, 471 N.W.2d 24 (1991)).

¶ 15. "Anticipatory warrants are peculiar to property in transit." Leidner, 99 F.3d at 1425. Such warrants may be issued prior to the contraband being located at the premises. Thus, in the context of an anticipatory warrant,

[t]he probable cause doctrine does not require that the contraband to be seized must presently be located at the premises to be searched, only that there is probable cause to believe that a crime has been (or is being) committed and that evidence of it can likely be found at the described locus at the time of the search.

United States v. Ricciardelli, 998 F.2d 8, 10 (1st Cir. 1993). See also Leidner, 99 F.3d at 1427.

¶ 16. In determining whether probable cause exists to issue an anticipatory search warrant, we must consider the "totality of the circumstances." Falbo, 190 Wis. 2d at 337. See also Leidner, 99 F.3d at 1427. The probable cause standard will not be satisfied unless the affidavit demonstrates that the contraband is on a "sure course" to the premises to be searched. Leidner, 99 F.3d at 1427 (citations omitted). We recognize that "government-controlled deliveries may be more likely to reach their destination than those deliveries expected within the normal course of a drug organization's operations." Id. at 1429.

¶ 17. In the present case, Koenig's affidavit stated that Kakonis is an experienced and reliable source who had on previous occasions provided her with accurate information regarding drug dealing. Koenig further stated that the package addressed to Mayor (i.e., Meyer) was intercepted because its appearance evidenced several indicia of drug dealing, and that the package was subsequently identified in a canine sniff as containing controlled substances. Further, as an officer with extensive training and experience in the identification of controlled substances, Koenig stated it was her belief that "there will be located in and upon those premises evidence of a crime." Finally, the package was delivered by Kakonis in a controlled manner, monitored by the officers, and the officers' execution of the search warrant occurred very soon after the delivery. Based upon the "totality of the circumstances," Leidner, 99 F.3d at 1427, we determine that there were sufficient facts provided to the court commissioner to establish probable cause to believe that controlled substances were on a "sure course," id., to the premises and would be present at 1033 St. Clair Street in She-boygan at the time the warrant was executed.

B.

¶ 18. Meyer also argues that the warrant was an unconstitutional anticipatory warrant because it does not contain any conditional language, that is, the warrant does not limit the officers' discretion in executing the warrant and does not sufficiently detail the events that must occur prior to its execution. Whether the language of the warrant satisfies the requisite constitutional requirements is a question of law. We review such issues of constitutional guarantees de novo. See State v. Andrews, 201 Wis. 2d 383, 389, 549 N.W.2d 210 (1996).

¶ 19. In Leidner, 99 F.3d 1423, the Seventh Circuit Court of Appeals addressed the need for specific conditional language in an anticipatory search warrant. The United States District Court for the Southern District of Illinois had determined that an anticipatory warrant's lack of an explicit requirement that the contraband be delivered prior to the execution of the warrant rendered the warrant invalid. See id. at 1425. In reversing the district court, the Leidner court stated that it found "no cases from this circuit requiring (as a matter of constitutional law) anticipatory warrants to explicitly state that the expected delivery must occur prior to execution of the warrant." Id. at 1427. The court recognized that although some courts appear to prefer conditional language, the only constitutional requirement in issuing an anticipatory search warrant is that it be supported by probable cause.¹⁵ Id. (citing Illinois v. Gates, 462 U.S. 213, 230 (1983)). We have already determined that the court commissioner had probable cause to issue the anticipatory search warrant; therefore, the warrant is valid.¹⁶

I — I I — I l-H

¶ 20. We next consider whether the officers no-knock entry into the premises during the execution of the anticipatory search warrant was an unconstitutional entry in violation of the Fourth Amendment to the United States Constitution. "Whether searches and seizures pass constitutional muster is a question of law, which this court reviews without deference to the lower courts." State v. Guy, 172 Wis. 2d 86, 93, 492 N.W.2d 311 (1992). Our analysis of this issue is appropriately preceded by a history of the development of Wisconsin precedent setting forth the rule of announcement and exceptions under which a no-knock entry is constitutional in cases involving felony drug investigations.

¶ 21. In State v. Cleveland, 118 Wis. 2d 615, 628, 348 N.W.2d 512 (1984), this court determined that police officers are justified in making a no-knock entry "only if they have particular grounds in the given case to give them reasonable cause to believe" that exigent circumstances exist.¹⁷ Despite the State's argument that drug dealers are generally likely to attempt to destroy evidence and are often armed, this court rejected the application of a "blanket rule" in narcotics cases that would allow an unannounced entry. See id. In a subsequent application of Cleveland this court held that a no-knock entry is justified if police have specific knowledge that an individual is in "possession of both firearms and large quantities of illegal drugs." State v. Williams, 168 Wis. 2d 970, 985, 485 N.W.2d 42 (1992).

¶ 22. In Stevens, 181 Wis. 2d at 425, we overruled our holding in Cleveland and adopted a blanket rule that police were justified in making a no-knock entry in an instance where there was evidence of felony drug delivery or dealing.¹⁸ Our decision in Stevens was based upon our determination that "the easily disposable nature of narcotics provides police with evidence sufficient to form a reasonable belief that no-knock entry is necessary to prevent the destruction of evidence." Id. (citations omitted).

¶ 23. We reaffirmed our adoption of the blanket rule in Richards I, 201 Wis. 2d at 847-48, holding that "exigent circumstances are always present in the execution of search warrants involving felonious drug delivery: an extremely high risk of serious if not deadly injury to the police as well as the potential for the disposal of drugs by the occupants prior to entry of the police." (Footnote omitted.) We concluded that police officers need not comply with the rule of announcement in the execution of a search warrant for evidence of felonious drug delivery. See id. Our decision to espouse the blanket rule was not unanimous, however. Justice Abrahamson concurred in the opinion in light of the facts presented in Richards I but rejected the blanket rule, advocating for dispensing with the rule of announcement only where the particular facts in a given case evince exigent circumstances such that the officer's no-knock entry is reasonable. See id. at 878.

¶ 24. On appeal the United States Supreme Court affirmed our judgment in Richards I but overruled our reaffirmation of the blanket rule approach first adopted in Stevens. See Richards II, 117 S. Ct. at 1421. The Supreme Court recognized that although drug investigations often involve special safety risks and the likely destruction of evidence, such is not the case in every drug investigation. See id. The Supreme Court also acknowledged concern regarding the relative ease of applying a blanket rule exception to other crimes, such as bank robberies, where risks of danger and evidence destruction are frequent. See id. In sum the Supreme Court agreed with the concurrence in Richards I.

Thus, the fact that felony drug investigations may frequently present circumstances warranting a no-knock entry cannot remove from the neutral scrutiny of a reviewing court the reasonableness of the police decision not to knock and announce in a particular case. Instead, in each case, it is the duty of a court confronted with the question to determine whether the facts and circumstances of the particular entry justified dispensing with the knock-and-announce requirement.

In order to justify a "no-knock" entry, the police must have a reasonable suspicion that knocking and announcing their presence, under the particular circumstances, would be dangerous or futile, or that it would inhibit the effective investigation of the crime by, for example, allowing the destruction of evidence. This standard. . .strikes the appropriate balance between the legitimate law enforcement concerns at issue in the execution of search warrants and the individual privacy interests affected by no-knock entries. This showing is not high, but the police should be required to make it whenever the reasonableness of a no-knock entry is challenged.

Id. at 1421-22 (internal citations omitted).

¶ 25. The Supreme Court reaffirmed its holding in Richards II in a recent unanimous opinion. See United States v. Ramirez, — U.S. —, 118 S. Ct. 992, 1998 WL 88055 (1998). In Ramirez, the Supreme Court stated that it rejected a blanket rule exception to the rule of announcement in felony drug investigations in Richards II. See id. at *4. Rather, an officer must consider the "particular circumstances" in each case. Id. (quoting Richards II, 117 S. Ct. at 1421). "Under Richards, a no-knock entry is justified if police have a 'reasonable suspicion' [under the particular circumstances] that knocking and announcing would be dangerous, futile, or destructive to the purposes of the investigation." Ramirez, 1998 WL 88055 at *4.

¶ 26. The parties in the present case agree that the blanket rule exception to the rule of announcement was rejected in Richards II but disagree regarding what type of particular information or evidence will satisfy the reasonable suspicion test justifying a no-knock entry.

¶ 27. The State contends that police officers may rely on their training and previous experience in similar situations to satisfy the particularity requirement. The State bases its argument in large part on Terry v. Ohio, 392 U.S. 1 (1968), and language therein which provides that an officer's reasonable suspicion may be based upon the nature of the crime. From this, the State apparently advocates that: (1) based upon prior experience in similar cases, an officer may reasonably infer that complying with the rule of announcement would result in danger or the destruction of evidence; and (2) such prior experience satisfies the reasonable suspicion test of Richards II for dispensing with the rule of announcement, as long as there is no specific evidence that would negate an officer's reasonable suspicion of danger or destruction in a particular case.

¶ 28. Meyer, on the other hand, argues that facts specific to a particular party must be shown to support reasonable suspicion that exigent circumstances exist. Meyer cites to language in Stevens which enumerated factors that may be considered in justifying dispensing with the rule of announcement, such as evidence of a party's prior sales of controlled substances or evidence of the amount of drugs involved in a particular case, and argues that no similar information was available to the officers in this case.

¶ 29. We hold that particular facts must be shown in each case to support an officer's reasonable suspicion that exigent circumstances exist. As such, we reject the State's proffered reasonable suspicion test which is essentially equivalent to the blanket rule rejected in Richards II.

¶ 30. In Richards II the Supreme Court placed an affirmative duty on officers to show reasonable suspicion under the particular circumstances that exigent circumstances exist to dispense with the rule of announcement. See Richards II, 117 S. Ct. at 1421. The State's proposed rule authorizes a no-knock entry during the execution of a search warrant in a felony drug investigation under any circumstance, absent information that would negate such generalized reasonable suspicion. Such a test would permit an officer to presume that there is reasonable suspicion in all cases involving felony drug investigations, thereby allowing the officer to step beyond the mandates of Richards II.

¶ 31. An adoption of the State's proposed test would hamper the protections against unreasonable search and seizure afforded to individuals under the Fourth Amendment to the United States Constitution. The "scheme of the Fourth Amendment becomes meaningful only when it is assured that. . .the conduct of those charged with enforcing the laws can be subjected to the more detached, neutral scrutiny of a judge who must evaluate the reasonableness of a particular search. . .in light of the particular circumstances." Terry, 392 U.S. at 21. See also Richards, 117 S. Ct. at 1421. In instances where no particular facts are presented to show exigent circumstances allegedly justifying a no-knock entry, there is nothing upon which a reviewing court can base a determination of reasonable suspicion.

¶ 32. Our holding that reasonable suspicion must be shown from particular facts does not thwart an officer's ability to also rely on his or her training and/or prior experience in similar cases. As the Supreme Court recognized in relation to the facts presented in Richards II, the "actual circumstances — petitioner's apparent recognition of the officers combined with the easily disposable nature of the drugs — -justified the officers' ultimate decision to enter without first announcing their presence and authority." Id. at 1422 (emphasis supplied).

¶ 33. The State cites to several United States Supreme Court cases that allow an officer to consider the nature of a crime as well as an officer's training or experience to satisfy the particularity requirement for reasonable suspicion. Our holding is consistent with each of those cases as in every instance the generalized knowledge of the officer was considered in combination with specific, particular facts. See, e.g., Terry, 392 U.S. at 27 ([D]ue weight must be given. . .to the specific reasonable inferences which [an officer] is entitled to draw from the facts in light of his experiences."); Florida v. Rodriguez, 469 U.S. 1, 6 (1984) (Stop was reasonable in light of "strange movements in [defendant's] attempt to evade the officers," "contradictory statements," and officer's "special training in narcotics surveillance and apprehension."); United States v. Cortez, 449 U.S. 411, 418 (1981) (Inferences can be made from "objective observations, information from police reports.. .and consideration of the modes of patterns of operation of certain kinds of lawbreakers."); United States v. Mendenhall, 446 U.S. 544, 565 (1980) (Powell, J., concurring) (Officers "observed respondent engaging in conduct that they reasonably associated with criminal activity."). An officer's experience and training are valid, relevant considerations. However, without an application of generalized knowledge to the particular facts of a given case, such considerations are insufficient to support a determination of reasonable suspicion.

¶ 34. Although we reject the State's proposed reasonable suspicion test, we do recognize that there may be instances where specific facts may negate an officer's otherwise reasonable act of dispensing with the rule of announcement. The reasonableness of an officer's decision to enter a premise without first knocking and announcing his or her presence must be evaluated by a reviewing court as of the time of the entry. See Richards II, 117 S. Ct. at 1422. Therefore, even if the particular facts initially available to an officer provide reasonable suspicion of exigent circumstances, that reasonable suspicion may be negated where additional facts are revealed prior the execution of the search warrant that would negate an officer's earlier suspicion of exigent circumstances. Cf. Cleveland, 118 Wis. 2d at 627 (Where a no-knock warrant has been issued "[circumstances which justify noncompliance with the rule of announcement. . .might change.. .before the officer's entry.").

¶ 35. We thus conclude that pursuant to Richards II, reasonable suspicion of exigent circumstances allowing an officer to dispense with the rule of announcement must be shown by the particular facts in each case.¹⁹ See Ramirez, 1998 WL 88055, at *4. Accordingly, the mere absence of specific facts that would negate reasonable suspicion is insufficient to justify a no-knock entry.

¶ 36. Our decision to affirm the court of appeals' reversal of the judgment of conviction is qualified. Although affirmation is appropriate given our holding, the remedy afforded Meyer must be appropriate to the constitutional violation that may have occurred in this case. See Waller v. Georgia, 467 U.S. 39, 49-50 (1984); State v. Webb, 154 Wis. 2d 320, 327, 453 N.W.2d 628 (1990), rev'd on other grounds, 160 Wis. 2d 622, 467 N.W.2d 108 (1991). The proper remedy is to remand this case to the circuit court for a new suppression hearing. See id. At the hearing the circuit court must determine whether, consistent with Richards II, the officers had a reasonable suspicion based upon the particular facts of this case that exigent circumstances existed to justify dispensing with the rule of announcement. If the evidence at the hearing satisfies the circuit court that reasonable suspicion existed to justify the no-knock entry, the judgment of conviction should be reinstated. See Webb, 154 Wis. 2d at 327.

> I — I

¶ 37. In sum, we conclude that the anticipatory search warrant in the present case was constitutional as it was supported by probable cause. We also conclude that there is no constitutional requirement that an anticipatory search warrant contain explicit conditional language limiting the execution of the warrant until after the delivery of the contraband. Finally we conclude that, consistent with the requirements set forth by the United States Supreme Court in Richards II, an officer may dispense with the rule of announcement when executing a search warrant if the officer has a reasonable suspicion, based upon the particular facts in a given case and the reasonable inferences drawn therefrom, that knocking and announcing the officer's presence would be dangerous or futile or inhibit the effective investigation of the crime. Furthermore, in determining whether reasonable suspicion exists, an officer's training and prior experience in similar situations may be considered in combination with the particular facts.²⁰

3 An anticipatory warrant is "a warrant based upon an affidavit showing probable cause that at some future time (but not presently) certain evidence of crime will be located at a specified place." 2 Wayne R. LaFave, Search and Seizure § 3.7(c), at 362 (3d ed. 1996).

4 The rule of announcement, also known as the "knock and announce" rule, "requires the police to do three things before forcibly entering a home to execute a search warrant: 1) announce their identity; 2) announce their purpose; and 3) wait for either the occupants to refuse their admittance or. . .allow the occupants time to open the door." State v. Stevens, 181 Wis. 2d 410, 423, 511 N.W.2d 591 (1994). The rule serves three purposes: 1) protecting the safety of police officers and others; 2) protecting the limited privacy interests of the occupants of the premises to be searched; and 3) preventing the physical destruction of property. See State v. Williams, 168 Wis. 2d 970, 981-82, 485 N.W.2d 42 (1992), overruled on other grounds, Stevens, 181 Wis. 2d at 430.

The rule of announcement is long-established:

In the 15th century, it was recorded that the sheriff could not break the door of a man's home to arrest him. The [federal] common law, however, did recognize the right of police officers to break the doors to arrest for a felony. Although the authorities differed somewhat as to what circumstances justified the breaking of doors, they universally required that the officer demand entry and announce his purpose — and be refused entry — before he could break in.

Patrick Crooks, Recent Decision, Federal Rules of Criminal Procedure — Arrest—State Law Governs Propriety of Arrest Made Under Federal Warrant Where Federal Rules Are Silent, 36 Notre Dame Lawyer 432, 432 (1961). American courts have recognized the rule of announcement as a common law requirement as early as 1813. See 2 Wayne R. LaFave, Search & Seizure § 4.8(a), at 598 (3d ed. 1996) (citing Bell v. Clapp, 10 Johns. 263 (N.Y.Sup.Ct. 1813)). Recently, the United States Supreme Court determined that the rule of announcement is also a constitutional requirement, holding that "this common law 'knock and announce' principle forms a part of the reasonableness inquiry under the Fourth Amendment." Wilson v. Arkansas, 514 U.S. 927, 929 (1995).

6 The Fourth Amendment to the United States Constitution states:

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

7 Article I, § 11 of the Wisconsin Constitution states:

The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures shall not be violated; and no warrant shall issue but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched and the persons or things to be seized.

We limit our decision to an analysis of Meyer's rights under the federal constitution as this court has "consistently and routinely conformed the law of search and seizure under the Wisconsin Constitution to the law developed by the United States Supreme Court under the Fourth Amendment." State v. Richards, 201 Wis. 2d 845, 850-51, 549 N.W.2d 218 (1996) (citations omitted), aff'd 520 U.S. —, 117 S. Ct. 1416 (1997).

8 Meyer also brought a motion to dismiss Count II of the information, charging him with possession of a Schedule I controlled substance without a tax stamp, as a party to a crime, contrary to Wis. Stat. §§ 939.05 and 139.95(1) and (2). The circuit court denied this motion to dismiss. Meyer does not raise the issue on appeal since the charge was later dismissed on motion of the State.

We note that in State v. Hall, 207 Wis. 2d 54, 67, 557 N.W.2d 778 (1997), this court struck down the stamp law requiring dealers to purchase tax stamps for illegal drugs in their possession, concluding it unconstitutionally compelled self-incrimination.

12 Under the exclusionary rule, evidence will be suppressed if it is "obtained as a direct result of an illegal search or seizure" or "later discovered and found to be derivative of an illegality." Segura v. United States, 468 U.S. 796, 804 (1984).

13 The court of -appeals did not address the validity of the search warrant, finding such a determination unnecessary in light of its holding that the execution of the search warrant violated Meyer's rights as guaranteed under the Fourth Amendment to the United States Constitution.

14 In United States v. Leidner, 99 F.3d 1423, 1425 (7th Cir. 1996), cert. denied, — U.S. —, 117 S. Ct. 1434 (1997), the court determined that, based upon its prior holding in United States v. Navarro, 90 F.3d 1245, 1251 (7th Cir. 1996), probable cause determinations with regard to the issuance of search warrants are to be reviewed de novo. We disagree. This court has previously determined that the " 'deferential standard of review is appropriate to further the Fourth Amendment's strong preference for searches conducted pursuant to a warrant.'" State v. DeSmidt, 155 Wis. 2d 119, 133, 454 N.W.2d 780 (1990) (quoting Massachusetts v. Upton, 466 U.S. 727, 733 (1984)). The factual scenario in Navarro did not involve a search warrant; rather, it involved the consensual search of a vehicle after a probable cause stop and a consensual search of the defendant's home. See Navarro, 90 F.3d at 1249-50.

15 Although language conditioning the execution of the warrant is not constitutionally required, the warrant in the present case is sufficient even if such conditional language were required. In her affidavit in support of the warrant, Koenig stated she believed that "illegal controlled substances" "will be located" on the premises, inferring that the search warrant would be executed only after the controlled delivery took place. See Leidner, 99 F.3d at 1427 n.4 ("We do not think an explicit conditioning statement is necessary where, as here, such a requirement is logically implicit."); United States v. Rey, 923 F.2d 1217, 1221 (6th Cir. 1991) ("A reasonable inference can be made that the warrant authorizes a search only after the controlled delivery has occurred.").

16 We recognize that the warrant in this case did not authorize a search for the intercepted mail package alone; rather, the warrant also authorized a search for other drug related paraphernalia. This does not render the warrant unconstitutionally overbroad. Where a search warrant is "based only on the knowledge of a controlled delivery," the warrant may authorize "a search for drug paraphernalia as well as contraband." Rey, 923 F.2d at 1220 (citations omitted).

17 Exigent circumstances "include a reasonable belief that announcement of police presence would endanger the safety of the police or others, or a reasonable belief that unannounced entry is required to prevent the destruction of evidence." State v. Cleveland, 118 Wis. 2d 615, 624, 348 N.W.2d 512 (1984) (citation omitted), overruled on other grounds, Stevens, 181 Wis. 2d at 430. Exigent circumstances may also exist "when it is evident from the circumstances that the authority and purpose of the police is already known to those within the premises" rendering the rule of announcement "a superfluous act." 2 Wayne R. LaFave, Search and Seizure § 4.8(f), at 620 (3d ed. 1996) (citations omitted).

18 On remand in Stevens the circuit court denied Stevens' motion to affirm the suppression order, relying on this court's holding in State v. Richards, 201 Wis. 2d 839, 549 N.W.2d 218 (1996). Stevens appealed, and the court of appeals reversed his conviction, relying on the United States Supreme Court's decision in Richards v. Wisconsin, 117 S. Ct. 1416. See State v. Stevens, 213 Wis. 2d 324, 570 N.W.2d 593 (Ct. App. 1997). The State petitioned this court for review, and we ordered the petition held in abeyance pending our decision in the present case.

19 In United States v. Ramirez, — U.S. —, 118 S. Ct. 992, 1998 WL 88055 (U.S. 1998), the United States Supreme Court held that the Fourth Amendment does not hold officers to a heightened standard of reasonable suspicion when a no-knock entry results in the destruction of property. Thus, although the officers used a ram to break down Meyer's door in the present case, the officers were not required to show more specific inferences of exigency to support their reasonable suspicion.

20 Because we conclude the warrant was constitutional and we are remanding this case for a determination of the constitutionality of the officers' no-knock entry, we find it unnecessary to consider an application of the exclusionary rule or the State's proffered argument that a good faith exception should apply.
