OPINION
Defendant Troy Master appeals the denial of his motion to suppress evidence found at his home during the execution of a search warrant. Defendant entered a conditional guilty plea to being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1) that preserved his right to appeal the denial of his motion to suppress. For the following reasons, the case is REMANDED to the district court for further proceedings consistent with this opinion.
STATEMENT OF FACTS
On January 14, 2007, Investigator George Dyer of the Franklin County, Tennessee Sheriffs Department submitted an affidavit in support of a search warrant for Defendant’s residence. On the affidavit, Defendant’s residence was listed as “9356 AEDC Road, Winchester Franklin County, Tennessee.” The affidavit included directions to a single wide trailer where *238 Defendant lived. Defendant’s residence, however, is actually in Coffee County, not Franklin County. 1
The search warrant was signed by Judge Thomas C. Faris on January 14, 2007. Judge Faris is a general sessions and juvenile court judge in Franklin County, Tennessee. As a general sessions judge in Franklin County, state law provided Judge Faris with the authority to sign warrants only for property in Franklin County itself. Less than three months before the search, on October 16, 2006, officers from the Franklin County Sheriffs Department had responded to a disturbance call at Defendant’s residence. Defendant was arrested for domestic violence. The charge was dismissed by Judge Faris less than a month before the search warrant in this case was issued because the proper venue was Coffee County, not Franklin County.
On January 15, 2007, Franklin County Sheriffs officers executed the search warrant in this case. During the search, Defendant informed the officers that he had a shotgun in the bedroom. On that basis, officers arrested Defendant, a former felon.
At the suppression hearing, Investigator Dyer testified that he believed Defendant lived in Franklin County because Dyer’s supervisor informed him that Defendant had registered as a sex offender in Franklin County using his current street address. Dyer also claimed he had spoken with a 9-1-1 operator at the Franklin County Sheriffs Department who informed him that she would dispatch a Franklin County Sheriffs Department vehicle if a call came from that address. Defendant presented testimony from an investigator hired by the Public Defender’s Office, Bill Dipillo. Dipillo testified that the Property Assessor for Franklin County plus the 911 dispatchers for Franklin and Coffee County all stated Defendant’s residence was in Coffee County. Dipillo also testified about the previous dismissal of the domestic violence charges by Judge Faris when the charges had been brought incorrectly in Franklin County instead of Coffee County.
The motion to suppress was denied on June 4, 2008. Defendant entered a conditional guilty plea on August 11, 2008. On November 10, 2008, Defendant was sentenced to 57 months’ imprisonment. This timely appeal followed.
DISCUSSION
“This court reviews a district court’s decision on a motion to suppress under two standards. ‘Findings of fact are upheld unless clearly erroneous, while conclusions of law are reviewed
de novo.’” United States v. Jenkins,
A. Whether the Search Violated Defendant’s Fourth Amendment Rights
Defendant’s sole challenge to the motion to suppress is that because the *239 Tennessee general sessions judge who signed the search warrant application presided in a different county from Defendant’s residence, the judge had no authority under Tennessee law to authorize the warrant. It is uncontested by the government that the authorizing judge, Judge Faris, did not have jurisdiction under Tennessee law to authorize a warrant for property in a different county. The question becomes whether this lack of authority is relevant in a prosecution occurring in federal court. For the following reasons, we determine that it is. 2
The government relies on a series of eases that hold that additional protections a state provides its citizens against search and seizure are irrelevant in federal prosecutions.
See, e.g., Virginia v. Moore,
The problem for the government in this case, however, is that the warrant is not invalid because of an additional protection provided by the state. Instead, the warrant is invalid because it does not comply with the Fourth Amendment. The jurisdictional limits placed on Judge Faris are not additional protections for a citizen but instead merely a reflection of the authority vested by the state in a general sessions judge. As we recognized in
United States v. Scott,
The government factually distinguishes Scott, but those distinctions do not compel a different outcome. In Scott, this Court granted a motion to suppress when the search warrant was signed by a retired judge. The judge occasionally substituted for active judges but was not working in that capacity when he signed the warrant. Therefore, when the judge in Scott approved the warrant, he had no authority to approve any warrants, while Judge Faris undoubtedly had authority to issue warrants for Franklin County.
However, the difference between the judge in
Scott
and Judge Faris are immaterial in determining the validity of a warrant. The Supreme Court laid out the requirements for the qualifications of a magistrate in
Shadwick v. City of Tampa,
Applying the rationale of
Shadwick,
the authorizing judge in this case is indistinguishable from that in
Scott.
While no allegation in the record suggests that Judge Faris was not neutral and detached, the same is true of the retired judge in
Scott.
Arguably, thousands of citizens in Tennessee satisfy the explicit requirement of
Shadwick
that the magistrate be “neutral and detached, and ... be capable of determining whether probable cause exists for the requested arrest or search.”
Id.
at 350,
*241 In this case, Tennessee law determines that Judge Faris only has authority to issue warrants in Franklin County. Judge Faris’ authority to issue warrants is codified at Tenn.Code Ann. § 40-5-102. State law, however, also provides that “[a] magistrate with jurisdiction in the county where the property sought is located may issue a search warrant authorized by this rule.” Tenn. R.Crim. P. 41(a). Judge Faris, as a Franklin County judge, simply did not have the authority to issue a warrant to search a property in Coffee County. We do not think the differences between the retired judge in Scott and Judge Faris are material. Tennessee law determined that the retired judge was not properly serving as a special judge, and thus had no authority to issue a warrant. Tennessee law determines that Judge Faris has no authority to issue a warrant for Coffee County.
A state is allowed to determine when a person is authorized to approve warrants, where that person has the authority to approve warrants, and what type of warrants that person is allowed to approve. To hold otherwise would allow federal courts to completely undermine state determinations of who is an authorized magistrate, and it is beyond question that we determine who is a qualified magistrate by consulting state law.
See United States v. Bennett,
B. Whether the Exclusionary Rule Should Be Applied
While the search of Defendant’s property based on an invalid warrant violated Defendant’s Fourth Amendment rights, the government argues that even if the warrant was invalid, the search should be upheld pursuant to the good faith exception of
United States v. Leon,
*242
We do not believe, however, that such a broad interpretation of
Scott
continues to be viable in light of more recent Supreme Court cases.
See, e.g., Herring v. United States,
— U.S.-,
The fact that a Fourth Amendment violation occurred — i.e., that a search or arrest was unreasonable — does not necessarily mean that the exclusionary rule applies. Indeed, exclusion has always been our last resort, not our first impulse, and our precedents establish important principles that constrain application of the exclusionary rule.
First, the exclusionary rule is not an individual right and applies only where it results in appreciable deterrence. We have repeatedly rejected the argument that exclusion is a necessary consequence of a Fourth Amendment violation. Instead we have focused on the efficacy of the rule in deterring Fourth Amendment violations in the future.
In addition, the benefits of deterrence must outweigh the costs. We have never suggested that the exclusionary rule must apply in every circumstance in which it might provide marginal deterrence. To the extent that application of the exclusionary rule could provide some incremental deterrent, that possible benefit must be weighted against its substantial social costs. The principal cost of applying the rule is, of course, letting guilty and possibly dangerous defendants go free — something that offends basic concepts of the criminal justice system. The rule’s costly toll upon truth-seeking and law enforcement objectives presents a high obstacle for those urging its application.
Herring,
This language is contrary to a foundational assumption of the opinion in
Scott
that: “Subject to a few exceptions, the exclusionary rule requires the suppression of evidence obtained in violation of the Fourth Amendment.”
Scott,
*243
The holding of
Herring
and other recent Supreme Court cases does not directly overrule our previous decision in
Scott.
Nonetheless, we believe that the Supreme Court’s evolving suppression rulings in Fourth Amendment cases require clarification or modification of our precedent in
Scott. See United States v. Clinton,
The Supreme Court has effectively created a balancing test by requiring that in order for a court to suppress evidence following the finding of a Fourth Amendment violation, “the benefits of deterrence must outweigh the costs.”
Herring,
In this case, if Dyer, the government’s primary witness, is to be believed, then suppression would not appear to be the appropriate remedy. According to Dyer, he sought a warrant in Franklin County in part because Defendant, himself, stated on his sex offender registration that his residence was in Franklin County. Nothing in the record indicates why the local police had any improper motivation to seek out Judge Faris as opposed to the general sessions judge for Coffee County.
While it appears at first blush that suppression might be inappropriate in this case, we will remand the case to the district court for the purposes of re-examining the facts and balancing the interests as required by
Herring.
When this matter was previously before the district court, the coxirt never made any factual findings related to the conduct of the officers, finding instead that the warrant did not violate Defendant’s Fourth Amendment rights. As stated above, we overrule that determination. On remand, the district court “must consider the actions of all the police officers involved,” not merely Dyer.
Herring,
CONCLUSION
For the foregoing reasons, the case is REMANDED to the district court for proceedings consistent with this opinion.
Notes
. In the district court, the government appeared to contest the location of Defendant’s residence, but the government made no argument in briefing to this Court that Defendant did not live in Coffee County.
. This Court has previously considered this question and issued a divided unpublished opinion finding the search did not violate the Fourth Amendment.
United States v. Franklin,
. While recent Supreme Court case law may foreclose the broadest possible interpretation of Scott advocated by Defendant, nothing in this opinion should cast doubt on the ultimate outcome in Scott. In that case, the officers made at best minimal attempts to find avail *243 able, active magistrates before presenting the warrant to the retired judge.
