OPINION
The United States appeals, pursuant to 18 U.S.C. § 3731 (2000), from an order of the district court suppressing evidence of a marijuana growing operation found in buildings controlled by James and Carol Elkins. The Elkinses, husband and wife, have entered conditional guilty pleas to several charges, 1 and appeal from rulings in the same order holding certain evidence from their buildings to be admissible. We affirm the order in part and reverse in part. Carol Elkins also appeals from an order of the district court releasing seized funds to pay the Elkinses’ attorneys’ fees. She claims the amount released was unreasonably small. We affirm the order.
I.
In the middle of 1996, Memphis police received anonymous information that there was a marijuana growing operation at 155 Scott Street, at the building behind 155 Scott, and at 1270 Tutwiler Avenue, James Elkins’s home.
The police began surveillance of the Scott Street property named'in the tip. This building was divided into two parts with separate doors and addresses, 139 Scott on one side and 155 Scott on the other. In intermittent surveillance of the building over a period of two months, the police saw James and Carol Elkins come and go from it. They also saw several men whom they recognized as off-duty Memphis police officers. On one occasion during the surveillance, the investigators approached James Elkins and spoke with him. Elkins told them he was employing off-duty policemen to safeguard his businesses against burglaries. Elkins said that he had businesses in the Scott Street *643 building and in a building close by on Neil Street. The police then turned their attention to 146 Neil Street, a nearby building where they had earlier seen several cars stopping at night. They observed a pallet near 146 Neil stacked with bags of sheep manure fertilizer. During the course of the surveillance the police also learned that James Elkins had at least one former felony conviction.
The officers began a more intensive surveillance of the Scott and Neil Street properties and the Elkinses’ home on the evening of August 20, 1996, aided by equipment and personnel from the Tennessee National Guard. They used a thermal imaging device to scan heat emanating from 139/155 Scott and 146 Neil, and detected an unusually high heat output at 146 Neil. 2 On that night police also encountered an off-duty officer named Smith guarding the Scott Street building. Smith stated that he worked for James Elkins, guarding both the Scott Street building and another Elkins building on Walnut Grove in Memphis. Smith led the investigating officers to this building, which was 2896 Walnut Grove. At one point he offered to let them in, but the police declined to enter. A police helicopter later flew over 2896 Walnut Grove and scanned it with an airborne thermal imager. This building also had a high heat signature.
Later that night Officer Frank Bell, accompanied by Captain Terry Livingston of the National Guard, went to 2896 Walnut Grove to inspect its exterior. A “No Trespassing” sign hung on the building. On its east side was an unpaved path used to reach an apartment building behind the Elkinses’ property. Stepping onto that path, Bell saw a PVC pipe protruding from the east wall of 2896 Walnut Grove at a height of two or three feet. There was an open gap of somewhat less than an inch in width around the exposed pipe. Bright light emitted from the gap. Bell and Livingston bent down and peered through it. Bell observed marijuana leaves inside the building; Livingston observed green leaves but did not identify them more precisely. Bell then called Officer Joe Hoing to the scene and Hoing also saw identifiable marijuana leaves through the gap. While bending down to look, Bell heard a sound from within the Elkinses’ building that he believed came from ballasts operating inside. 3
After making these observations, Bell and Livingston remained near 2896 Walnut Grove to continue surveilling it while other officers prepared a warrant application for the building. Hoing left to join a second group of officers investigating the Elkinses.
The next morning, Officers Hoing, Duane Gary, and Dion Cicinelli went to the Elkinses’ home at 1270 Tutwiler. They told the Elkinses they had received a complaint about a marijuana grow at Scott Street, but James Elkins denied any involvement with a marijuana grow. He gave the officers permission to search his home, and Carol Elkins escorted them through parts of it. The officers saw no contraband, but each later testified that there was a strong, identifiable odor of marijuana in the Elkins home. The officers then requested permission to search 155 Scott. James Elkins agreed, saying *644 that the police could look anywhere they wanted to. 4
Elkins then drove Gary to Scott Street in his own car, choosing an indirect, circuitous route. The other officers followed, but Carol Elkins did not accompany them. At one point during the drive Elkins made a cellular phone call to an unidentified individual. Officer Gary testified that he could not hear what Elkins said but believed he was speaking to his wife.
Once Elkins arrived, he led the officers through 155 Scott, where they found nothing incriminating. The officers asked if they could also search 139 Scott, the other portion of the building. Elkins verbally agreed to this search; the officers testified that he said “sure.”
When the officers emerged from 155 Scott with James Elkins, they saw an unoccupied Cadillac newly parked next to the building. The officers recognized it as Carol Elkins’s car, which had been parked at the Elkins home that morning. James Elkins attempted to unlock the door to 139 Scott, but could not find a matching key. He called to his wife, who was now inside the building, to open the door. Carol El-kins eventually opened the side door and admitted James Elkins and the officers.
The officers searched 139 Scott, accompanied by the Elkinses. They eventually found a cabinet which, when opened, contained metal trays of marijuana. They also found plant chemicals, fertilizer, scales, ledger sheets, and other paraphernalia possibly linked to marijuana growing. At one point the officers turned their attention to 139 Scott’s attic, and James Elkins pointed out a ladder that the police could use to access that area. In the attic the officers found several electric lights.
During the search the officers came to suspect that there was a hidden space between the walls of 139 and 155 Scott. Elkins admitted that there was such a space. When it became clear that the officers intended to open a hole in the wall to access it, Elkins pointed out a spot where the hole could be made with the least damage to the building. The officers found a hidden room containing a great deal of equipment used in growing marijuana. Remnants of marijuana growing were visible on the floor.
The officers then asked Elkins for permission to search 146 Neil. Elkins at first agreed to the search, but then verbally declined and asked to speak with his attorney. The officers testified that Elkins said that a search of 146 Neil would only make things harder for himself. The Elkinses, now handcuffed, were taken to the police station around 11;00 a.m. Officers Hoing, Gary, and Cicinelli began preparing affidavits for warrants to search 146 Neil, 2896 Walnut Grove, and the Elkinses’ home at 1270 Tutwiler.
While the affidavits were being prepared, Officer Bell and Captain Livingston were at 2896 Walnut Grove, watching the location from their car. At around noon, a car containing two Hispanic males drove up to the building. The car stopped close to the building’s entrance. By this time Bell and Livingston had learned of the *645 arrests of the Elkinses. They began to drive toward the stopped car, intending to keep the occupants from - entering 2896 Walnut Grove. One of the occupants, later identified as Jesus Morales, got out of the car and entered the building. The officers pulled up next to the car and detained the remaining occupant, Raul Sandoval. As they detained Sandoval, Morales exited 2896 Walnut Grove, saw the officers detaining his colleague, and went back inside, locking the door. Livingston was wearing a police shirt and camouflage pants when Morales saw him.
Bell then radioed Officer Hoing to seek advice about how to secure the building. Hoing eventually contacted a state prosecutor. The prosecutor advised the officers to enter 2896 Walnut Grove, remove the man inside it, and wait for a warrant.
The officers entered 2896 Walnut Grove by forcing the locked door. Inside the building they found four men, including Morales. They also observed an extensive array of marijuana plants as well as two shotguns. The police then left the building, but one of the men they had seized told them that two more men were inside. The police re-entered the building twice to search for other persons. Using a police dog, they eventually uncovered a space in the ceiling where two additional men were hiding. The officers arrested all six men.
The officers obtained the three search warrants that afternoon, and executed them later on August 21. Their search of 2896 Walnut Grove uncovered an extensive marijuana growing operation, including approximately 1300 marijuana plants and dozens of high intensity growing lights. At 146 Neil the officers found 320 live marijuana plants and 700 harvested plants. They also arrested two men found in the building and seized some weapons. At the Elkinses’ home at 1270 Tutwiler, the police again discovered an array of contraband. They found evidence of a dormant marijuana growing operation in the Elkinses’ attic, four pounds of marijuana in a bag inside a wall, and a quantity of cocaine on a stairway leading to the attic. The following day, a different team of officers obtained a second warrant to search 1270 Tutwiler for hidden compartments, but found nothing. In the days that followed the police obtained several other warrants to search properties controlled by the Elkinses, but those searches are not relevant here.
James and Carol Elkins were indicted, then re-indicted, for a range of drug offenses involving the possession, manufacture, and distribution of marijuana, as well as money laundering and firearms possession.
The Elkinses moved to suppress the evidence seized from their buildings and requested an evidentiary hearing under
Franks v. Delaware,
In a published suppression order, the district court upheld some of the searches but invalidated others. First the court considered at length the admissibility of the thermal imaging data. It held that the police use of thermal imagers to scan the Elkinses’ buildings without a warrant was a violation of the Fourth Amendment, and excluded all thermal imaging evidence.
United States v. Elkins,
The Elkinses entered conditional guilty pleas to charges involving the drugs seized at 139 Scott and 146 Neil, creating, as to them, an appealable final decision. Each party then appealed the district court’s adverse rulings to this court.
II.
The government challenges the district court’s holding that the use of thermal imagers to scan the Elkinses’ properties was a Fourth Amendment search requiring a warrant.
See
At the time the briefs were submitted, most circuits had held that using a thermal imager was not a search, even when the device was used to scan the home,
5
which receives the greatest protection under the Fourth Amendment. The Tenth Circuit had held that warrantless thermal imaging of a home did violate the Fourth Amendment, but the court en banc later vacated that opinion, leaving the issue unresolved.
See United States v. Cusumano,
The landscape changed sharply on June 11, 2001, when the Supreme Court handed down
Kyllo v. United States,
While
Kyllo
broadly protects homes against warrantless thermal imaging, the case before us involves the use of a thermal imager to scan the Elkinses’ commercial buildings. There is a reasonable expectation of privacy in business premises, yet it is less than the reasonable expectation of privacy enjoyed by the home.
New York v. Burger,
*647
Courts should avoid unnecessary constitutional questions.
Spector Motor Serv., Inc. v. McLaughlin,
III.
James Elkins challenges the district court’s holding that he validly consented to the police search of 139 Scott Street. El-kins argues that his original consent to search did not include 139 Scott, and that any apparent consent he gave later to search that location was coerced and invalid,
The relevant legal principles are summarized in
United States v. Riascos-Suarez,
A search may be conducted without a warrant if a person with a privacy interest in the [place] to be searched gives free and voluntary consent. A court will determine whether consent is free and voluntary by examining the totality of the circumstances. It is the Government’s burden, by a preponderance of the evidence, to show through “clear and positive testimony” that valid consent was obtained. Several factors should be examined to determine whether consent is valid, including the age, intelligence, and education of the individual; whether the individual understands the right to refuse to consent; whether the individual understands his or her constitutional rights; the length and nature of detention; and the use of coercive or punishing conduct by the police.
Id.
at 625 (citations omitted). We can only reverse the district court’s factual finding that James Elkins voluntarily consented if it is clearly erroneous.
United States v. Erwin,
The district court did not err in holding that James Elkins was capable of validly consenting to the search. Valid consent may be given by someone with an actual privacy interest in the place to be searched,
Riascos-Suarez,
The government argues that Elkins voluntarily consented to a search of 139 Scott at two different times: during the officers’ initial conversation with James Elkins at his house at 1270 Tutwiler, and during their later interactions with him at 155 Scott.
The district court found that at first Elkins specifically consented only to a search of 155 Scott Street. A consensual search is normally limited by the scope of the consent that supports it.
Walter v. United States,
There was significant evidence that El-kins voluntarily consented to the search of 139 Scott at this time. Elkins was allowed to drive the officers to Scott Street in his own car. He showed the officers through the office rooms in 155 Scott Street. The officers asked Elkins if they could see the 139 Scott part of the building, and he verbally assented. Their testimony, which Elkins did not challenge below, was that he replied “sure.” Elkins was not handcuffed at this time. The officers did not draw their weapons while in Elkins’s presence. Elkins called to his wife to admit the officers into 139 Scott, and she did so. Inside the building, Elkins showed the officers a ladder that they could use to reach an attic space they wished to inspect. In addition, Elkins’s earlier remark at 1270 Tutwiler that the police could search anywhere they wanted sheds light on his later interactions with the officers, suggesting willing cooperation on Elkins’s part.
Elkins stated in an affidavit that one of the officers took him by the arm and led him to 139 Scott Street. He also stated that the officers became agitated when they spotted Carol Elkins’s car in front of the building, and demanded entry into the building. James Elkins claims that the officers’ behavior at this -point made him fear for his wife’s safety. The district court viewed Elkins’s testimony as giving “some indication of coercion,” but found that his claim that he feared for his wife’s safety was not justified by objective evidence in the record.
Next, as the district court observed, the circumstances of this case conclusively demonstrated that James Elkins was aware of his right to refuse consent to a search. On the same day that he agreed to the searches, of 139 and 155 Scott, Elkins refused to allow police to search his property at 146 Neil Street. 7
*649 In light of these circumstances, the district court did not clearly err in finding that the evidence of free and voluntary consent outweighed the suggestion of coercion that it thought James Elkins’s testimony might have raised. Even if the conversation between Elkins and the officers at the Elkins home did not establish consent to search 189 Scott, the later events at Scott Street did. Hence the illegal drugs and other evidence discovered in the building are admissible.
IV.
The Elkinses argue next that the district court erred by holding that the warrant affidavit for 146 Neil Street, 8 as redacted by the court after the evidentiary hearing, established probable cause to search that building. We conclude the district court correctly upheld the affidavit and search.
At an evidentiary hearing held pursuant to
Franks v. Delaware,
We review for clear error the district court’s findings about the truth or falsity of statements in the affidavit, and about the reckless character of any falsehoods.
See United States v. Ayen,
We consider the challenged statements in the affidavit for 146 Neil Street individually. We begin with the statement in the affidavit that police searched 139 Scott with James Elkins’s consent and found “a large indoor marijuana grow room along with ... [two] pounds of marijuana” within it. In Part III of this opinion, supra, we uphold the district court’s conclusion that James Elkins validly consented to the officers’ search of 139 Scott Street. Thus, the district court properly permitted the incriminating items discovered in the 139 Scott search to be included in the affidavit *650 to search 146 Neil Street. This statement will remain.
The affidavit further reports that 146 Neil Street is “behind” 139 Scott Street, where drugs had been found. More precisely, as the district court found, and as the Elkinses emphasize, 146 Neil is to the rear and at an angle to 139 Scott. Another building, 154 Neil, is directly behind 139 Scott. The district court deemed this discrepancy immaterial. The materiality question is close, but the language in the affidavit properly conveys that 146 Neil is in close proximity to the drug location at 139 Scott. Moreover, the affidavit also speaks of 146 Neil as being “in the rear” of 139 Scott, and this is accurate: the Elkinses’ own exhibits show that 146 Neil lies to the back of 139 Scott Street. A stairway attached to 139 Scott apparently overlooks the back of 146 Neil. Warrant language may fall short of technical exactitude without necessarily violating the materiality and scienter requirements of
Franks. See Pelham,
That conclusion, in turn, throws light on another portion of the affidavit. The affidavit also states that police were investigating “an indoor marijuana grow complaint at 139 Scott ... and 146 Neil.” The Elkinses argue that there is no evidence in the record that police received a complaint about 146 Neil Street. The district court did not explicitly discuss the Elkinses’ arguments, but did not strike the statement from the affidavit. Its decision not to do so appears to follow from two conclusions reached in its opinion. First, the court found as a fact that police received an anonymous complaint about a marijuana growing operation in 155 Scott (the same building as 139 Scott) and the building behind it. This finding is supported by the testimony of Officer Cicinelli and is not clearly erroneous in light of the other record testimony. Second, as discussed above, the court concluded that it was not improper, for Franks purposes, for the officers to speak of 146 Neil as being behind 139/155 Scott. Hence this statement too remains.
Next, the affidavit states that the police asked James Elkins for consent to search 146 Neil Street; that Elkins consented; and that he then “decided not to give consent[,] advising that [doing so] would only make things harder for himself.” James Elkins contests whether he made the statement that searching 146 Neil would make things harder for himself. If Elkins did not make the statement, including in the affidavit the claim that he did would surely violate Franks. The district court, however, retained this portion of the affidavit. The inclusion of this incriminating statement is supported by the testimony of Officers Gary and Hoing. The district court’s apparent finding that El-kins made the statement is not clearly erroneous.
The affidavit further states that 139 Scott and 146 Neil are “owned by James Elkins.” In fact, James Elkins was a tenant of both properties, leasing them from corporations controlled by his wife. The district court, however, found this discrepancy did not violate
Franks.
Next, the affidavit states that the officers spotted, “behind 146 Neil and next to 139 Scott Street,” a pallet that contained some “bags of sheep manure ... which is used in the growing of marijuana.” At the
Franks
hearing, the government presented expert testimony stating that sheep manure is indeed so used. The district court retained the statement, paraphrasing it as a statement that the pallet was “outside” 146 Neil Street. The El-kinses challenge this holding on appeal, claiming that the sheep manure fertilizer was closer to the nearby building at 137 Scott Street than it was to 146 Neil. Because the Elkinses did not present this argument to the district court, it is not properly before us for consideration.
See United States v. Edge,
Finally, the affidavit included a statement that police had received “information from a C/I [i.e., confidential informant] that Elkins [was] growing marijuana in ... 146 Neil.” The district court found that the police had actually received an
anonymous
tip that marijuana was being grown in 155 Scott Street and “the building behind Scott Street.”
The question then comes down to whether the redacted affidavit established probable cause.
10
While in normal circumstances a warrant affidavit’s sufficiency is assessed with “great deference by ... reviewing courts,”
Pelham,
V.
The United States challenges the district court’s decision to suppress the evidence taken from 2896 Walnut Grove. The district court held that Officer Bell violated the Elkinses’ expectation of privacy in 2896 Walnut Grove by walking up to the hole around the exposed PVC pipe and peering into it without “sufficient probable cause and exigent circumstances.”
The government argues for reversal on all points. First, it claims that the police lawfully observed marijuana plants inside 2896 Walnut Grove by peering through a gap around a PVC pipe that projected from the wall of the building. Second, it claims that exigent circumstances later arose that justified a warrantless entry into the building to prevent the destruction of evidence. We are persuaded by the government in both respects, and reverse the district court’s holding that the warrant was invalid.
A.
It is settled that observations of “objects falling into the plain view of an officer who has a right to be in the position to have that view ... may be introduced in evidence.”
Harris v. United States,
1.
We begin by asking whether Officer Bell had “a right to be in the position” where he was when he peered through the opening in the east side of 2896 Walnut Grove. Put another way, we ask whether the Fourth Amendment prohibited Bell from walking up to the pipe. The Elkinses argue that the officers crossed into a zone of protected “curtilage” in order to peer through the hole. The district court’s analysis of this issue was somewhat opaque. It did not separate the curtilage question from the question whether Bell’s look through the gap, once he was in place, was in itself a search. The court’s discussion did, however, cite
Dow Chem. Co. v. United States,
Neither has this court decided whether there are circumstances in which the area adjoining a business structure is protected against physical entry like the curtilage of a home. There is precedent for such a view,
see United States v. Swart,
Whatever curtilage protection a business may receive in light of
Dow
is presumably limited by the Supreme Court’s later decision in
Dunn,
which held that police were entitled to cross a barbed-wire fence and approach to the very edge of the defendant’s barn in order to peer within using flashlights.
See
The area next to the PVC pipe at issue in this case was accessible to the public. Bell ventured onto a “path appar
*654
ently used to gain access to an apartment building behind the Elkins property.”
Elkins,
There may be circumstances in which the area adjoining a business structure is sufficiently private to enjoy a protection analogous to a home’s curtilage. We hold, however, that even if “business curtilage” is a viable doctrine in this Circuit, it does not apply here. The path next to 2896 Walnut Grove was, for Fourth Amendment purposes, a place which police could enter under the “open fields” doctrine.
See Oliver,
2.
The next issue is the permissibility of the look itself. The district court held that when Bell looked into the gap around the pipe, he violated the Elkinses’ reasonable expectation of privacy in their building’s interior.
The Elkinses do have a reasonable expectation of privacy in the interiors of their businesses, but that fact does not insulate those spaces against plain view observation. In
Dunn
the Supreme Court assumed that the barn into which the police peered was protected against warrant-less physical entry, but held that it was not a search for the police to shine a flashlight through a net-covered opening above the barn’s front gate and scrutinize its interior.
Any contortions Bell made to peer through the opening did not change the “plain view” character of his observation. The fact “that the policeman may have to crane his neck, or bend over, or squat, does not render the [plain view] doctrine inapplicable, so long as what he saw would have been visible to any curious passerby.”
James v. United States,
B.
Exigent circumstances permitting police to enter a structure without a warrant may arise when evidence of drug crimes is in danger of destruction.
See United States v. Sangineto-Miranda,
Here, several of the events that contributed to the possible existence of exigent circumstances were prompted by Morales’s observation of the police detaining his companion Sandoval outside the building. Therefore we first ask whether the officers’ initial detention of Sandoval was lawful. Police cannot “manufacture” exigent circumstances through unlawful or unreasonable actions, then invoke those circumstances to justify a warrantless entry into a building.
See, e.g., United States v. Buchanan,
The district court held that the police improperly tipped off Morales that police were on his trail by detaining Sandoval “without probable cause,” and that the exigent circumstances doctrine therefore did not apply.
The fact that the detention of Sandoval appears to have alerted Morales to the presence of police does not render the exigent circumstances doctrine inapplicable. As long as police refrain from unreasonably tipping off suspects, they may use normal investigative and law enforcement measures in the vicinity of a suspected crime location without forfeiting their ability to perform a warrantless search to secure evidence if exigent circumstances arise.
See Ewolski v. City of Brunswick,
To establish that the events observed at 2896 Walnut Grove gave rise to exigent circumstances, then, the government must satisfy a two-part test, demonstrating: (1) a reasonable belief that other persons are inside the building; and (2) a reasonable belief that these persons are likely to destroy evidence of a crime.
See United States v. Bates,
As the district court acknowledged, the circumstances here satisfied the first part of the test. Police watched one of the two men’ from the car enter 2896 Walnut Grove, emerge from it, see the police detaining his companion, and then re-enter the building.
Whether police had a reasonable belief that destruction of material evidence was likely is an issue requiring more detailed consideration. Certainly the police had ample reason to suspect that 2896 Walnut Grove contained material evidence of an illegal drug operation. As discussed in Part V.A. supra, they had directly observed marijuana leaves inside the building by peering through the exposed gap around the PVC pipe. They knew that 2896 Walnut Grove was controlled by James Elkins and that marijuana had just been found in one of Elkins’s other buildings. They had also received an anonymous tip that Elkins was growing marijuana. The district court held that police did not have a reasonable belief that drugs were present, but its conclusion rested on its erroneous exclusion of the officers’ observations through the gap. We have reversed this holding of the district court, and also reject its conclusion that police had no reasonable belief that drugs were present.
The district court, however, went on to rule that even if the officers did have a reasonable belief that evidence was inside the building, they did not have a reasonable belief that the person or persons inside would be likely to destroy that evidence, and so still failed the second part of the exigent circumstances test.
We disagree with this conclusion as well. Here no additional evidence of likely destruction was needed. This court has several times applied the exigent circumstances doctrine in situations where suspects had ready access to evidence of drug crimes. The decisions emphasize the question whether, immediately prior to the warrantless search, police had objective grounds to believe that suspects were aware that police were close on their trail. When the answer to this question is yes, this court has regularly held that exigent circumstances existed to support a war-rantless search of the location in question.
Thus, in
Sangineto-Miranda
the court held that exigent circumstances were present when police, who had strong reason to think a suspect had drugs in an apartment, lawfully arrested the suspect’s colleague, who had left the apartment on a brief
*657
errand during the negotiation of a drug deal.
In
United States v. Straughter,
Similarly, in
United States v. Ukomadu,
Conversely, in
United States v. Radka,
Here, it was clear that the man who entered 2896 Walnut Grove was aware of the close presence of police when he spotted them outside detaining his colleague. His observation of the police and re-entry into the building (“high-tail[ing] it inside,” in the words of one of the officers), provided an objective basis for fearing the destruction of relevant evidence, namely the illegal marijuana that the police had observed inside the building. We hold that exigent circumstances existed to support a warrantless entry into the building for the purpose of securing it. 13
*658
It follows that evidence that the police observed while securing the premises is admissible and was properly included in the warrant affidavit to search 2896 Walnut Grove.
See Arizona v.
Hicks,
VI.
The government next argues that the district court erred by holding inadequate the two affidavits used to procure warrants to search the Elkinses’ home at 1270 Tut-wiler.
The first affidavit, dated August 21, 1996, stated: (1) officers visited James El-kins’s home at 1270 Tutwiler to speak with him about a complaint that Elkins was growing marijuana at 139 Scott Street; (2) Elkins then invited the officers inside; (3) the officers could smell a strong odor of marijuana in the house; (4) the officers had substantial experience identifying the smell of marijuana; and (5) the officers had received a tip from a “C/I” (confidential informant) stating that Elkins was growing marijuana at his home at 1270 Tutwiler and in an adjacent building.
See Elkins,
With respect to the last statement above, the district court found that the police had a tip about 1270 Tutwiler, but it came from an anonymous informant. As with the 146 Neil warrant affidavit, it held that this was a material discrepancy suggesting reckless falsity. See Part IV supra. ■ The court ruled that “the statement ... characterizing the anonymous caller as a confidential informant” would • “not be considered” in deciding whether the warrant was supported by probable cause. Id. at 827. We hold, as we did in considering the 146 Neil affidavit, that this ruling was correct as to materiality and not clearly erroneous as to reckless falsehood.
There is a question, though, about how much of the warrant text should be excised as a result of this misrepresentation. Since the district court specifically found that the police
did
receive a tip with the content claimed in the affidavit (albeit an anonymous one), it would not be appropriate to strike all references to the tip from the affidavit—only the false reference to the informant’s “confidential” character should be struck. It is not entirely clear to us that the district court proceeded in this way, since it did not summarize the contents of the redacted 1270 Tutwiler affidavit after finishing its analysis. However, we believe that this approach is prescribed by
Franks v. Delaware.
In that decision, the Supreme Court made clear that a showing of a
Franks
violation requires no more or less than that “the affidavit’s false material [be] set to one side,” while “the affidavit’s remaining content” is analyzed to see whether it creates probable cause.
*659 The Elkinses did not dispute below the affidavit’s statement that the officers’ experience permitted them accurately to identify the smell of marijuana. The district court’s analysis cast no doubt on the assertion. Hence it also remains.
The affidavit also stated that police detected a strong odor of marijuana in the house. The district court’s suppression order discussed this in several places as a factual dispute.
See
That conclusion, coupled with the uncontested statement that the officers were experienced at recognizing the smell, goes a considerable way toward establishing the warrant’s validity. This court has held that an officer’s detection of the smell of marijuana in an automobile can by itself establish probable cause for a search.
United States v. Garza,
Because the second affidavit to search 1270 Tutwiler, dated August 22, 1996, followed quickly on the first warrant, and properly recounted the array of illegal contraband that the police found there when executing the first warrant, we hold that the second warrant was also supported by probable cause.
VII.
Early in the prosecution, the government seized assets controlled by the El-kinses and began civil forfeiture proceedings. The Elkinses voluntarily waived an adversary due process hearing on these seizures in return for the government’s promise to release seized funds in an amount judicially determined to be necessary for reasonable attorneys’ fees. The Elkinses requested $350,950, stating that they needed this amount to hire their counsel of choice. A magistrate judge extensively analyzed the likely course of the litigation and recommended releasing $100,000, with a right to review the amount for good cause. The district court affirmed the magistrate’s order but increased the amount to $150,000.
Carol Elkins argues that the district court committed reversible error by not releasing the Elkinses’ assets in the full amount sought. We have recognized, in the similar context of reviewing rates for fee awards to civil rights plaintiffs, that in deciding an appropriate level of fees for a given litigation the district court “is entitled to substantial deference.”
Reed v. Rhodes,
VIII.
In summary, we affirm the district court’s suppression order insofar as it held that the warrantless search -of 139/155 Scott was justified by James Elkins’s consent, and that the redacted search warrant affidavit for 146 Neil established probable cause. We reverse the order insofar as it held that exigent circumstances did not exist for the warrantless search of 2896 Walnut Grove, and that the redacted search warrants for 2896 Walnut Grove and the Elkinses’ home at 1270 Tutwiler were invalid. We also affirm the district court’s order authorizing the release of seized funds to pay counsel.
We remand for further proceedings in conformity with this opinion.
Notes
. James Elkins pleaded guilty to the Superseding Indictment's Count 3 (possessing and manufacturing marijuana with intent to distribute, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2); Count 12 (money laundering, in violation of 18 U.S.C. § 1956(a)(l)(A)(i) and 18 U.S.C. § 2); and Count 18 (possession by convicted felon of firearms shipped in interstate commerce, in violation of 18 U.S.C. § 922(g)). Carol Elkins pleaded guilty to the Superseding Indictment's Count 12 (money laundering). Most of the other charges against the Elkinses were severed.
. High heat outputs may be a'sign that a building houses a marijuana growing operation, since the indoor cultivation of marijuana commonly employs high-energy lamps.
Kyllo v. United States,
. Ballasts are electrical devices commonly used to regulate current flow to high-wattage lamps and other items.
. Testimony was inconsistent on whether the officers' initial request to search also mentioned the 139 Scott address. Elkins testified that the officers asked only about the 155 Scott address. Hoing testified that Elkins specifically consented to a search of 139 Scott. Cicinelli said he thought Hoing referred to 155 Scott in the conversation. The district court found that "specific permission was only given to search 155 Scott Street at that time!”

Crowder,
. The text of the affidavit is reproduced in the district court's opinion.
. Reference to "recklessness” here and in the remainder of this opinion should be understood to encompass intentional disregard as well.
. The district court entered contested Franks rulings on other statements in the affidavit, but we need not consider them.
. As previously noted, we ignore the thermal imaging evidence that the district court struck from the affidavit, though we do not decide whether this evidence was correctly excluded.
. The leading treatise states: "If police using the naked eye or ear are able to see or hear [objects or events inside a business] while located on adjoining property or even on property of the business which is readily ac~ cessible to the general public, this is not a search.” 1 Wayne R. LaFave, Search and Seizure: A Treatise on the Fourth Amendment § 2.4(b), at 536 (3d ed.1996).
. As a final consideration supporting the warrantless entry here, we note that the police had already applied for a warrant when the car drove up to 2896 Walnut Grove. Thus, this was not a case where the police chose to forego seeking a warrant "in the hope that exigent circumstances would arise.”
