OPINION
Appellant challenges the district court’s suppression of evidence seized pursuant to a search warrant containing a no-knock provision. We affirm.
FACTS
An officer of the Warren police department applied to the Marshall County District Court for a warrant to search the trailer home owned by respondent Esmerelda Rivera Martinez and occupied by Martinez and respondent Salvador Hernandez Otero. The court authorized an unannounced no-knoek, nighttime search warrant, and officers executed it on June 28, 1997. The officers seized a rifle, cocaine, and heroin and arrested Martinez and Otero. Martinez and Otero were charged with controlled substance crimes in the first, second, third, and fifth degrees, failure to affix tax stamp, and endangerment of a child. Otero was also charged with being a felon in possession of a firearm.
Martinez, later joined by Otero, filed a motion to suppress the evidence seized pursuant to the search warrant, claiming that probable cause did not exist to support the warrant, and a motion to disclose the confi *146 dential informants’ identities. The district court denied these motions.
Martinez and Otero filed a second motion to suppress the evidence and claimed, in relevant part, that the no-knock provision in the search warrant violated their constitutional rights. The district court granted this motion and suppressed all the evidence obtained pursuant to the search warrant. The state appeals from the district court’s pretrial suppression order.
ISSUES
1. Did the district court apply the incorrect standard of review when reviewing the decision to authorize a no-knoek search warrant?
2. Did the district court err in concluding that the no-knock search warrant should not have been issued?
3. Did the district court err in excluding all the evidence obtained pursuant to the search warrant?
ANALYSIS
On appeal from a pre-trial order suppressing evidence when the district court’s decision is a question of law and there is no factual dispute, “the reviewing court may independently review the facts and determine, as a matter of law, whether the evidence need be suppressed.”
State v. Othoudt,
1. Standard of Review Applied by District Court
The state initially argues that the district court erred in reviewing de novo the magistrate’s decision to issue a no-knock search warrant.
A court should not review de novo a magistrate’s probable cause determination supporting a search warrant, but should give “great deference” to the magistrate’s determination.
State v. Wiley,
Here, however, the district court was not simply reviewing the facts but, rather, was making a legal determination in light of a newly released United States Supreme Court decision,
Richards v. Wisconsin,
2. No-Knock Search Warrant
The state argues that the district court erred in concluding that the no-knock warrant was improperly issued and unconstitutional.
The “knoek-and-announee principle forms a part of the Fourth Amendment reasonableness inquiry.”
Wilson v. Arkansas,
In order to justify a ‘no-knoek’ 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.
Richards,
520 U.S. at —,
First, when police seeking a search warrant have reason to believe that an unannounced entry will be required in order to successfully and safely execute the warrant, they must inform the issuing magistrate of the circumstances which they believe justify the unannounced entry and obtain specific advance authorization for it. Second, in order to obtain such authority the police must make a strong showing that an announced entry will result in the *147 destruction of evidence or in danger to the officers executing the warrant.
a. In this regard, the officer must do more than simply make a showing that drugs are involved. In fact, we question whether an unannounced entry clause can ever be justified in a warrant to search a dwelling for drugs when there is no indication that the drugs are other than for personal use and where there is no averment of specific facts indicating that an unannounced entry is needed in order to safely and successfully execute the warrant.
b. However, if the affidavit contains a showing of necessity — e.g., a showing that the occupants are prepared to destroy evidence whenever the search warrant is executed or that the dwelling is being used as an outlet or a warehouse for a drug business — then the request for the unannounced entry clause should be granted.
The third governing principle is that even if police obtain advance judicial authorization for an unannounced entry into a dwelling, the police still should make a threshold reappraisal of the need to execute the warrant in this manner.
The fourth governing principle is that if police have no reason to seek advance authorization or if advance authorization is denied, the police still may make an unannounced entry to execute the warrant if facts arising at the threshold strongly indi; cate that an unannounced entry is necessary in order to safely or successfully execute the warrant.
State v. Lien,
Although
Lien
states that there may be no blanket rule permitting unannounced entries in narcotics cases, no-knock searches have been permitted solely because a home is suspected to be an outlet for drug sales.
See Lien,
After the United States Supreme Court’s recent decision in
Richards v. Wisconsin,
however, it is questionable whether Minnesota may have a blanket rule that drug outlets may automatically be subject to no-knock searches. In
Richards,
the Supreme Court struck down Wisconsin’s blanket rule permitting no-knoek search warrants in felony drug cases. 520 U.S. at, —,
Here, the search warrant application and supporting affidavit stated that an unannounced entry was necessary “to prevent the loss, destruction or removal of the objects of the search [and] to protect the safety of the peace officers.” The reasons given to support this request were: (a) the trailer home was not easily accessible without being seen by the occupants; and (b) the applying officer was “aware that persons who traffic in controlled substances are often armed with firearms and other dangerous weapons and will use these weapons.”
The officer’s statement that because of his experience he knew that the occupants would likely have and use weapons was merely the
*148
officer’s general observation and not particularized to Martinez and Otero. The only particularized reason given for the no-knock search here was the fact that approaching officers could easily be seen by the home’s occupants. The search warrant also permitted execution at night, however, which would likely have minimized this problem. Information that Martinez and Otero may have been operating a drug outlet in their home is not a particularized reason demonstrating a safety threat to officers or a threat that evidence would be destroyed.
See Lien,
Even if there was insufficient evidence in the warrant application and supporting affidavit to support a no-knock provision, the officers could have supported a no-knoek execution of the warrant by showing that particularized circumstances at the time of execution required entrance without warning.
See Lien,
There were no particularized reasons in the affidavit requesting a warrant that indicate a no-knock provision was necessary in this ease and the state did not introduce any evidence that the facts at the time of execution required an unannounced entry. Because under Richards there cannot be a blanket rule permitting no-knock searches based solely on evidence that a home may be being used as an outlet for drug sales, the district court did not commit clear error by concluding that the no-knoek provision violated Martinez and Otero’s constitutional rights.
3. Evidence Suppression
The state argues that even if the warrant improperly included a no-knoek provision, the district court should not have suppressed the evidence.
A. Independent Source/Inevitable Discovery
The state first argues that the evidence would have been “inevitably discovered” and/or it was obtained pursuant to an “independent source.”
Pursuant to the exclusionary rule, evidence recovered during an unlawful search may not be introduced at trial.
State v. Lozar,
The independent source doctrine does not apply to this case. The police conducted no other investigation that would have led to the discovery of the drugs.
See id.
(noting lack of separate investigation made independent source doctrine inapplicable). Further, the inevitable discovery doctrine cannot be applied to this case. When police obtain evidence in a warrantless search, the evidence may not be admitted under the inevitable discovery doctrine simply because a warrant
could
have been obtained.
State v. Hatton,
B. Good Faith Exception
The state also argues that the evidence should be admitted because the officers acted in good faith. In
Leon,
the United States Supreme Court adopted the good faith exeep
*149
tion to the exclusionary rule.
United States v. Leon,
Minnesota has not recognized a good faith exception to the exclusionary rule for a violation of the Minnesota Constitution.
State v. Kahn,
In
Kahn,
this court affirmed the district court’s determination that probable cause did not support a search warrant and refused to apply the good faith exception.
The police did not commit misconduct here. Their failure to provide sufficient, particularized reasons for requesting a no-knock provision, however, is the type of conduct the exclusionary rule is intended to prevent. Thus, the good faith exception cannot be applied in this case.
DECISION
The district court did not clearly err in suppressing the evidence discovered pursuant to the search warrant. The search warrant application did not provide sufficient, particularized reasons for requesting a no-knock search.
Affirmed.
