AMENDED OPINION
Defendant-Appellant, Clarence Pennington (“Pennington”), pleaded guilty to possession with intent to distribute 79.2 grams of crack cocaine, in violation of 21 U.S.C. § 841. Pennington reserved his right to appeal the order of the district court denying his motion to suppress the evidence obtained following the issuance and execution of a state search warrant. After a hearing, the Magistrate Judge issued a Report and Recommendation proposing that the motion be denied. Subsequently, the district court denied the motion to suppress.
Pennington raises three issues on appeal. First, he contends that the district court erred in finding that the search warrant was issued by a neutral and detached magistrate. Second, he asserts that the good faith exception in
United States v. Leon,
I.
It is well established that this Court reviews the district court’s findings of fact in a suppression hearing under the clearly erroneous standard, while the district court’s conclusions of law are reviewed

novo. United States v. Avery,
A. The Issuer of the Search Warrant
The warrant at issue in this ease was issued under state law by a Shelby County Judicial Commissioner. Essentially, Pennington contends that Shelby County Judicial Commissioners are not neutral and detached in that they are appointed by a local legislative authority, the Shelby County Commission. Under Tennessee law, the legislative body of a county having a population in excess of 700,000 may appoint one or more judicial commissioners who are authorized to issue search warrants upon a finding of probable cause. Tenn.Code Ann. § 40 — 1—111(a)(1)(A) (Supp.2002). The same statute provides that the term of office of such judicial commissioners shall be established by the legislative body, with the proviso that such term may not exceed four years. § 40-1-111(a)(1)(B). The statute further provides that the judicial commissioner shall receive compensation determined by the same legislative body. § 40-l-lll(a)(2).
Appellant contends that these provisions of Tennessee law impermissibly place a legislative body, the Shelby County Commission, in ultimate control of the judicial commissioners. Appellant also asserts that such arrangement violates Art. II, Sec. 1 of the Constitution of Tennessee, which separates governmental powers into the familiar three-part alignment of executive, legislative, and judicial authority.
The Magistrate Judge, as well as the District Judge, relied upon
United States v. Leon, swpra,
to hold that the officers relied in good faith on the warrant issued by the judicial commissioner. The Report and Recommendation was issued by the Magistrate Judge on August 28, 2000, pri- or to this Court’s decision in
United States v. Scott,
In United States v. Scott, this Court decided that the Leon exception to the exclusionary rule is not applicable if the judicial officer issuing a search warrant is wholly without legal authority. Id. at 515. In Scott, the judge who issued the search warrant had retired and had no state-law authority to issue a search warrant. Under these circumstances, law enforcement officers could not rely upon the Leon exception. Id.
Pennington essentially contends that a judicial commissioner appointed by a legislative body of a county who is not a judge or even an attorney may not lawfully issue a search warrant or act as a neutral magistrate for purposes of the Fourth Amendment. The caselaw clearly rejects this position.
In
Shadwick v. City of Tampa,
A unanimous Supreme Court held:
The substance of the Constitution’s warrant requirements does not turn on the labeling of the issuing party. The warrant traditionally has represented an independent assurance that a search and arrest will not proceed without probable cause to believe that a crime has been committed and that the person or place named in the warrant is involved in the crime. Thus, an issuing magistrate must meet two tests. He must be neu *218 tral and detached, and he must be capable of determining whether probable cause exists for the requested arrest or search. This Court long has insisted that inferences of probable cause be drawn by “a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime.”
The requisite detachment is present in the case at hand. Whatever else neutrality and detachment might entail, it is clear that they require severance and disengagement from activities of law enforcement. There has been no showing whatever here of partiality, or affiliation of these clerks with prosecutors or police. The record shows no connection with any law enforcement activity or authority which would distort the independent judgment the Fourth Amendment requires.... While a statutorily specified term of office and appointment by someone other than “an executive authority” might be desirable, the absence of such features is hardly disqualifying. Judges themselves take office under differing circumstances. Some are appointed, but many are elected by legislative bodies or by the people. Many enjoy but limited terms and are subject to re-appointment or re-election. Most depend for their salary level upon the legislative branch. We will not elevate requirements for the independence of a municipal clerk to a level higher than that prevailing with respect to many judges.
Id.
at 350-51,
A somewhat similar challenge to the authority of a judicial commissioner under Tennessee law was addressed by this Court in
United States v. King,
Appellant in the case at bar supports his position with the testimony of Officer Black, who stated that the judicial commissioner in this case had never rejected a warrant sought. The record, however, is devoid of any estimate of how many search warrants Officer Black had requested. Further, in the absence of any other evidence on the issue, it is just as logical to conclude that Officer Black presented affidavits in support of search warrants which justified the issuance of such requested process. The record is insufficient to draw any conclusions as to the lack of neutrality of the judicial commissioner who issued the search warrant in this case.
Finally, a number of other courts have found that no constitutional violation occurs when a search warrant is issued by a non-lawyer.
United States v. Mitro,
*219 Pennington’s constitutional challenge to the authority of a Shelby County Judicial Commissioner to issue a valid search warrant is without merit.
B. Knock and Announce Rule
The Appellant next challenges the search itself, contending that the officers violated the knock and announce rule as articulated under Fourth Amendment jurisprudence. Pennington contends that the district court erred in finding that the officers knocked and waited a sufficient period of time under the circumstances before forcibly entering his dwelling.
The Magistrate Judge made the following factual findings, which were adopted by the district court: At approximately 3:45 p.m. on November 30, 1999, six to seven Memphis police officers came to Pennington’s residence to execute the search warrant. All of the officers were wearing shirts marked “Police.” A chain-link fence surrounded the house. Beyond these facts, the record contains a sharp divergence in testimony.
Four officers testified concerning the timing of the entry into Pennington’s home. Detective Wright testified that he was the first officer to reach the front door. As he banged on the door, he yelled in a loud voice “Memphis Police Department. Search Warrant.” Wright also testified that he then heard footsteps that sounded as if someone was running away from the door. Wright estimated that approximately eight to ten seconds passed after he announced his presence, at which point he used a pry bar device to force open the front door.
Officer Tilton also testified that he heard Wright knock on the door and announce “Police.” Tilton estimated approximately ten seconds elapsed between the knock and the prying open of the door. Detective Black further corroborated Detective Wright and Officer Tilton and estimated that approximately eight seconds elapsed between the announcement and the breaking of the door. Finally, Lieutenant Ber-ryhill testified that he heard Detective Wright announce the police presence. He estimated that between eight and fifteen seconds elapsed between the announcement and the forced entry.
Three defense witnesses testified at the hearing. All three stated that they did not hear a knock on the door and did not hear the police announce their presence before the door was forced open. All three witnesses instead testified that the first time the police announced their presence occurred after the forced entry of the dwelling.
The Magistrate Judge focused on factual inconsistencies involved in the testimony of two of the three defense witnesses. William Jennings, for example, testified that he was seated on the front porch of a friend’s house across the street from Pennington’s residence. A second defense witness testified, however, that he and Jennings were occupying a car on the street at the time the officers pulled up to the Pennington residence. In addition, all three defense witnesses testified that they did not discuss their observations of the events in question with any other person between the time of the events and their testimony before the Magistrate Judge, which the Magistrate Judge found unbelievable.
The Magistrate Judge, whose findings were adopted by the District Court, resolved the disputed testimony by concluding that the officers’ testimony was more credible in light of all the circumstances. Accordingly, the District Court concluded *220 that between eight to ten seconds elapsed between the knocking on the door and the forced entry into Pennington’s dwelling. This factual finding is not clearly erroneous and therefore is accepted by this Court.
The legal issue presented by Pennington is whether the officers violated the knock and announce principles set forth in
Wilson v. Arkansas,
Given the longstanding common-law endorsement of the practice of announcement, we have little doubt that the Framers of the Fourth Amendment thought that the method of an officer’s entry into a dwelling was among the factors to be considered in assessing the reasonableness of a search or seizure. Contrary to the decision below, we hold that in some circumstances an officer’s unannounced entry into a home might be unreasonable under the Fourth Amendment.
This is not to say, of course, that every entry must be preceded by an announcement. The Fourth Amendment’s flexible requirement of reasonableness should not be read to mandate a rigid rule of announcements that ignores countervailing law enforcement interests.
Id.
at 934,
In
United States v. Spikes,
Nonetheless, we decline their invitation to create a bright-line rule for every case, i.e., that waiting less than five seconds is per se unreasonable while waiting more than five seconds is per se reasonable under the Fourth Amendment.
The Fourth Amendment’s “knock and announce” principle, given its fact-sensitive nature, cannot be distilled into a constitutional stop-watch where a fraction of a second assumes controlling significance.
Id. at 926. 2
In Spikes, the Court considered a number of factors in determining whether the forcible entry made 15 to 30 seconds after the police knocked and announced their presence was reasonable under the Fourth Amendment. The Court first noted that the officers were authorized to search for drugs and that they could assume that persons inside the residence might destroy the evidence “before it could be seized.” Id. Second, prior to executing the warrant, *221 the officers reasonably believed that potential drug traffickers at the residence might have lookouts and be armed. Id. Risks to the officers would increase the longer they delayed entry into the home. Third, the officers executed the warrant during the middle of the morning, a time people are typically awake and involved in everyday activities. Id. at 927. Consequently, less time is needed to respond to a knock on the door. Finally, the Court noted that the officers used a bullhorn to advise those inside the residence of their presence. Id. The bullhorn was loud enough to alert many people in the neighborhood that a search was underway and many neighbors came out of their homes to observe what was happening. Based upon these factors, the Court concluded that the officers did not violate the knock and announce rule by waiting 15 to 30 seconds before entering the residence. Id.
More recently, in
United States v. Pinson,
In this case, the officers were also searching for drugs. The record does not contain evidence that the owner of the home or occupants thereof were armed. But the warrant was executed at 3:45 in the afternoon which, as in
Spikes
and
Pin-son,
was a time that people were presumably awake and engaged in everyday activities. As observed in
Spikes,
“the amount of time officers need to wait before entering a home necessarily depends on how much time it would take for a person in the house to open the door. When the police execute a warrant in the dead of the night ... the length of time the officers should wait increases.”
Spikes,
One additional factor present in this case is the testimony of Detective Wright that he heard the sound of footsteps, indicating someone was running away from the front door. Such fact would indicate to a reasonable police officer that the request for entry was being effectively denied, that the person inside the home was taking some type of evasive action, including the possible destruction of contraband, and that the person inside the home was aware that police were seeking entry to his home.
Under the analysis in
Spikes
and
Pinson,
and given the testimony of Detective Wright, eight to ten seconds was a reasonable period of time for the officers to wait before forcing entry into the home. Our conclusion is bolstered by the fact that, unlike the circumstances in
Spikes
and
Pinson,
the officer who knocked on the door testified that he heard a person running away from the door after he knocked and announced the presence of the police. Under such circumstances, an eight-to-ten second wait by the police is objectively reasonable under the Fourth Amendment to justify a forced entry into the residence based upon a search warrant.
3
Other courts, including other pan
*222
els of this Court, have found similar periods of time sufficient to justify the entry into the home without the owner’s permission.
United States v. Johnson,
II.
Based upon the foregoing, the decision of the district court is AFFIRMED in all respects.
Notes
. With regard to a search warrant issued under federal law, Fed.R.Crim.P. 41(a) limits the authority to issue search warrants to a Federal Judge or Magistrate Judge or a state judge sitting on a court of record. Thus, the warrant issued in this case could not have been issued under federal law. Fed.R.Crim.P. 41(a) does not apply to state warrants, even if the evidence or contraband recovered is used in a federal criminal prosecution.
United
*219
States v. Heacock,
. The search warrant at issue in this case was issued and executed under state law. A search warrant executed under federal law must also meet the conditions set forth in 18 U.S.C. § 3109. Under the statute, before an officer may forcibly enter a house to execute a search warrant, the officer must be "refused admittance" or the officer must be in the process of liberating himself or a person aiding in the execution of the warrant. The Fourth Amendment standard articulated in
Wilson
is somewhat similar to that set forth in § 3109 in that under the statute, after law enforcement announce their presence and intention to search the home, a delay of a certain period of time in effect constitutes a "refused admittance.”
See United States v. Ramirez,
. In his Petition for Rehearing, Pennington argues that the original opinion in this case is irreconcilable with the decision in
United States v. Dice,
. The Ninth Circuit alone has focused solely on the number of seconds between the knock and the forced entry. In
United States v. Banks,
