Defendant-Appellant Antonio R. Henry (“Henry”) appeals his conviction for possession of ammunition by a convicted felon, in violation of 18 U.S.C. §§ 922(g)(1) and 924(e). Henry argues that the district court erred first by denying his motion to suppress evidence obtained during a probation officer’s search of a bag found at his residence and then by treating the United States Sentencing Guidelines as mandatory while sentencing him. Henry also con *606 tends for the first time on appeal that § 922(g)(1) exceeds Congress’s power under the Commerce Clause.
Because the probation search was founded upon neither reasonable suspicion nor consent, we REVERSE the district court’s denial of Henry’s motion to suppress and VACATE Henry’s conviction and sentence. This result makes it unnecessary for us to reach the sentencing issue. Finally, we reject Henry’s commerce-power argument.
I. BACKGROUND
On October 8, 2003, Henry was discharged from a Kentucky prison pursuant to a grant of shock probation. See Ky. Rev. Stat. Ann. § 439.265. The following day, Henry reported to Probation Officer Michael Havens (“Officer Havens”) for the first time. At that meeting, Henry filled out a releasee’s report, indicating that he was unemployed, received SSI payments, and resided at 2821 Northwestern Parkway. A condition of Henry’s probation forbade Henry either to change the residence listed on this report without the approval of his probation officer or to have more than one residence at a time. Joint Appendix (“J.A.”) at 53 (Conditions of Supervision ¶VI.D). Henry also was required either to maintain full-time employment or to seek employment when unemployed. J.A. at 51 (Order on Motion for Shock Probation ¶ 8), 53 (Conditions of Supervision ¶¶ VI.B, VII.A.4).
Subsequent to the initial meeting on October 9, 2003, Officer Havens made three visits to 2821 Northwestern Parkway in order to verify that Henry resided there. On October 13, 2003, Officer Havens made two visits to the reported address: the first in the morning and the second in the afternoon. 1 On October 20, 2003, Officer Havens made one visit at some time between 8:00 A.M. and 4:30 P.M., but he could not recall a more precise time. On each occasion, nobody answered Officer Havens’s knocks on the front and back doors, and Officer Havens observed no movement or noise. Officer Havens made no other efforts to verify Henry’s residence: Officer Havens made no attempt to reach Henry at his reported phone number, either before or after his home visits, and he did not ask any neighbors whether Henry lived at the residence. Officer Havens testified that, in his experience, it is “relatively common” for probationers to live somewhere other than the addresses they report, and he concluded that Henry “probably didn’t live at that address.” J.A. at 80-81 (Suppression Hr’g Tr. at 8-9) (Havens Test.).
On October 22, 2003, Henry made his next scheduled report to Officer Havens. At that meeting, Henry filled out another releasee’s report and once again indicated that he was unemployed, received SSI payments, and resided at 2821 Northwestern Parkway. Officer Havens informed Henry that he was going to send two officers *607 home with Henry in order to verify his residence. Officer Havens testified that upon hearing this news, Henry “acted very erratic, very nervous.” J.A. at 83 (Suppression Hr’g Tr. at 11) (Havens Test.).
At Officer Havens’s request, Probation Officers Melanie McClish (“Officer McClish”) and Christopher Tally (“Officer Tally”) went with Henry to 2821 Northwestern Parkway in order to verify that Henry lived there. Henry let the officers in, but neither officer recalled whether Henry had a key to the house. While Officer Tally remained downstairs with Henry, Officer McClish went upstairs to examine Henry’s room.
Officer McClish saw that the room that Henry claimed was his had a dresser and was “cluttered with clothes,” but it did not have a bed. J.A. at 101 (Suppression Hr’g Tr. at 33) (McClish Test.). Officer McClish had the impression that the room “just didn’t look like it was occupied.” Id. Officer McClish began looking in the room for items — such as “[cjlothes, pictures, ... deod[o]rant” — indicating that Henry lived there. Id. Officer McClish saw a gym bag in an open closet; she picked the bag up, noticing that it was very heavy. Officer McClish opened the bag and found in it a firearm and ammunition. 2
Henry was indicted for possession of ammunition by a convicted felon, in violation of 18 U.S.C. §§ 922(g)(1) and 924(e). Henry made a motion to suppress the ammunition, arguing that the officers had neither reasonable suspicion nor consent to conduct the search. The district court denied Henry’s motion, holding that the officers had reasonable suspicion to conduct the search. The district court did not address the consent issue.
A jury found Henry guilty. At sentencing, the district court found that Henry was an armed career criminal who possessed ammunition in connection with a crime of violence. Relying on
Blakely v. Washington,
II. ANALYSIS
A. Motion to Suppress
Henry argues that the district court should have granted his motion to suppress because (1) the officers lacked reasonable suspicion to search the bag containing the ammunition and (2) he did not consent to the search. 3
1. Standard of Review
“ ‘When reviewing the denial of a motion to suppress, we review the district court’s findings of fact for clear error and its conclusions of law de novo.’ ”
United States v. Oliver,
2. Probationary Search
The Supreme Court first addressed the constitutionality of the search of a probationer’s home in
Griffin v. Wisconsin,
When analyzing the validity of a probationary search under the Fourth Amendment, we follow the Court’s example by applying its “two-pronged inquiry.”
United States v. Loney,
a. The Kentucky Search Policy
Applying the two-step
Griffin
analysis to the instant case, the first question is whether the Kentucky search policy that authorized the complained-of search is reasonable under the Fourth Amendment. Pursuant to statutory authority, Ky. Rev. Stat. Ann. §§ 196.030, 196.035, 439.430, 439.470, the Kentucky Department of Corrections promulgated a policy “[t]o establish guidelines for Probation and Parole
*609
Officers ... relating to search and seizure” and other issues. J.A. at 56 (Kentucky Corrections Policies and Procedures 27-16-01 (issued May 14, 2001) [hereinafter Corrections Policies],
incorporated by reference in
501 Ky. Admin. Regs. 6:020 (2003)). As interpreted by the Kentucky Supreme Court, the policy provides that an officer may conduct a war-rantless search if he has “reasonable suspicion ‘that the performance of the search may produce evidence to support [an alleged violation of Appellant’s parole].’ ”
Coleman v. Commonwealth,
We assessed an earlier version of this policy in
United States v. Payne,
We cannot simply rely on
Payne
to conclude that the whole policy is reasonable, however, because another part of the policy has been modified to make its scope broader. While the policy in
Payne
provided for a warrantless search “upon reasonable suspicion that the [probationer] is in possession of contraband,”
6
Because Kentucky’s probationary search policy incorporates both the quantum of evidence (i.e., reasonable suspicion) approved in Payne and the breadth (i.e., not just contraband but any probation violation) approved in Loney, we hold that the policy is reasonable under the Fourth Amendment.
b. The Search Itself
Having determined that the Kentucky search policy is reasonable, we turn now to the second step of the
Griffin
inquiry: whether the complained-of search conformed with the regulations, i.e., whether there was reasonable suspicion to conduct the search.
7
“Reasonable suspicion is
*610
based on the totality of the circumstances and has been defined as requiring ‘articu-lable reasons’ and ‘a particularized and objective basis for suspecting the particular person ... of criminal activity.’ ”
Payne,
In
People v. Lampitok,
In
United States v. Dally,
In
United States v. Crew,
In each case, there were articulable, particularized facts supporting the officers’ reasonable suspicion that the defendant had violated his residency condition. First, there was evidence that the defendant was living at some unreported address. This evidence was in the form of either the statements of people who lived with the defendant at the unreported address, as in Lampitok and Crew, or from officers’ observations of the defendant at the unreported address engaging in activities indicating that he lived there, as in Dally. In contrast, here there was absolutely no evidence that Henry lived at some unreported address.
Second, in each case above there was evidence that the defendant was no longer living at his reported address. This evidence was in the form of the statements of people who had lived with the defendant at the reported address in Lampitok, the defendant’s failure to respond to a phone message left with a relative in Dally, or the defendant not being at home during an unannounced visit after he had already falsely reported his address and phone number on a prior occasion in Crew.
In the case at bar, the government relies on the following facts as evidence that Henry did not live at his reported address: (1) Henry was not present during *612 the three times that Officer Havens visited Henry’s reported address; (2) Henry was unemployed and received SSI payments; (3) in Officer Havens’s experience, it is common for a probationer not to live at the address he reports to his probation officer; and (4) Henry appeared nervous when Officer Havens informed him that two probation officers would accompany him home to verify his residence. For the reasons discussed below, these facts and the inferences that Officer Havens drew from them are inadequate to constitute reasonable suspicion that Henry no longer lived at his reported residence.
First, Officer Havens inferred from the fact that he received no response during his three home visits that Henry was not home at those times. But it “is not necessarily true” that someone is not at home when he or she does not answer the door; Henry “may have simply not answered the door.”
United States v. Sundiata,
Second, even though Henry was required either to maintain full-time employment or to seek employment when unemployed, Officer Havens inferred from the fact that Henry was unemployed and received SSI payments that he should have been at home during the day. Officer Havens testified, however, that Henry had not yet provided verification of his SSI status, and that only upon providing such documentation would Havens ask the state court to relieve Henry of the employment conditions. When Henry indicated at his first meeting with Officer Havens that he was unemployed and receiving SSI payments, Officer Havens presumably informed Henry — as any conscientious probation officer would do — that Henry would continue to be bound by the employment conditions. Therefore, one would reasonably expect Henry to be away from his residence during the day either to work or to seek work. Yet Officer Havens expected Henry to be at home when Havens visited Henry’s residence during the day. We refuse to let Officer Havens have it both ways.
Moreover, Officer Havens’s inference fails to appreciate that there are any number of reasons — other than to work or to find work — why Henry might have been out of the house, such as to shop for groceries, to see a doctor, or to visit with friends. Indeed, Henry could have been attempting to comply with his probation order’s mandate to obtain a GED, J.A. at 51 (Order on Motion for Shock Probation ¶ 7), by attending classes during the day. Officer Havens’s inference is especially suspect in light of his testimony that the probation conditions neither limited when Henry could leave his residence, J.A. at 86, 90 (Suppression Hr’g Tr. at 16, 20) (Havens Test.), nor required that he be home when a probation officer planned an unannounced home visit, J.A. at 88, 90 (Suppression Hr’g Tr. at 18, 20) (Havens Test.). Indeed, the probation conditions did not even place Henry under a curfew condition. J.A. at 52 (Conditions of Supervision HILA), 86 (Suppression Hr’g Tr. at 16) (Havens Test.). If Henry was free to leave the house at night, why would he be less free to leave the house during the day? In light of all these possibilities, one *613 wonders why Officer Havens did not leave any indication that he had been trying to reach Henry, as the officers reasonably did in Dally (by leaving a phone message with a relative) and Crew (by leaving a card at the door).
Officer Havens’s third inference — that, based on his experience of having other probationers lie about their residences, Henry probably was lying, too — is not suspect in and of itself. An officer may make a reasonable suspicion determination “based on the reasonable inferences he may draw ‘in light of his experience.’ ”
United States v. Foster,
Finally, the government offers Henry’s nervousness upon being told that two probation officers would accompany him home to verify his residence, presumably because it bolsters all of Officer Havens’s inferences. “[N]ervousness has been considered in finding reasonable suspicion in conjunction with other factors.”
United States v. Richardson,
Because the government has pointed not to “articulable reasons” and “a particularized and objective basis” that Henry violated the residency condition of his probation but instead to a chain of tenuous infer-enees, we hold that the officers did not have the requisite reasonable suspicion to conduct the search. Having failed the second step of the Griffin probationary-search analysis, the search was unreasonable under the Fourth Amendment.
3. Consent
The government argues that even if it did not have reasonable suspicion to conduct the challenged search, Henry consented to it by agreeing to probation conditions that included a search provision. The Supreme Court has explicitly declined to address whether a probationer consents to suspicionless searches by agreeing to a search condition.
11
United States v. Knights,
The government argues in the alternative that even if Henry did not give a blanket consent by agreeing to his probation conditions, he specifically consented to the instant search, itself via his words and conduct. Officer McClish testified that Henry did
not
expressly consent to a search of the bag, so .the government’s logic is that Henry consented to the search by consenting to the home visit. The government cites as support for the purported verbal consent Officer McClish’s testimony that “[w]e did consent with him beforehand.” J.A. at 107 (Suppression Hr’g Tr. at 39) (McClish Test.). As evidence that Henry consented to the search through his conduct, both officers testified that he let the officers into the residence. Because it upheld the search on the basis of reasonable suspicion, the district court did not reach the consent issue. We need not remand the case, however, beeausé even if we take as true the government’s factual allegations that Henry consented to a home visit,
15
as a matter of law the scope of Henry’s consent did not include the search of his bag.
16
See United States v. Jenkins,
“When law enforcement officers rely upon consent as the basis for a warrantless search, the scope of the consent given determines the permissible scope of the search.”
United States v. Garrido-Santana,
There are, however, two important reasons not to hew blindly to the expressed-object approach in this setting. First, in a search for evidence that a probationer genuinely lives at his reported address, there is no identifiable “expressed object.” This problem is demonstrated amply by the instant case. Officer McClish testified that she was looking for “[a]nything” to indicate that Henry lived at his reported residence. J.A. at 101 (Suppression Hr’g Tr. at 33) (McClish Test.). She listed clothes, photographs, and deodorant as .examples but also noted that his bedroom did not have a bed in it. The great variety in size, shape, and typical location of just these four items illustrates the far-reaching search that would be authorized if we were to peg the scope of consent simply to the object of the search. Every time a probationer permitted an officer to enter his home in connection with a search for proof that he lived there, he would be subjecting to search every space, paper, and container in his home. We think it plain that no reasonable person would understand a probationer’s consent to extend so far simply by letting officers visit his home to look for signs of residence. The fact that the expressed-object analysis seemingly mandates this absurd result demonstrates its diminished utility in this setting. Therefore, where the expressed-object approach collides with the reasonable-person approach, the better course is to maintain fidelity to the Court’s more general principle of reasonableness, which is “[t]he touchstone of the
*617
Fourth Amendment” and is the overall standard by which the scope of consent is measured.
Jimeno,
Second, the expressed-object inquiry ignores the relevance of probation conditions and regulations in this context. The Court has explained that probation conditions and regulations are “salient eircum-stanee[s]” to the reasonableness of suspicion-based probationary searches.
Knights,
Henry’s probation conditions included two provisions governing officer conduct at his residence: the search condition and the visit condition. The search condition provided that Henry might be subject to search and seizure if his probation officer had reason to believe that he had “illegal drugs, alcohol, volatile substance, or other contraband” on his person or property. J.A. at 52 (Conditions of Supervision ¶V.A). The visit condition provided that Henry had to permit his probation officer to visit his residence at any time but made no provision for search or seizure. J.A. at 53 (Conditions of Supervision ¶VI.A). A reasonable person would evaluate the scope of a probationer’s consent in light of these two conditions. If a probationer consented to officers entering his residence to look for contraband, a reasonable person would view the consent to encompass that which the search condition authorizes: a full search of his person and residence. In contrast, if a probationer consented to- officers entering his residence simply to verify his address (a purpose which is decidedly not within the scope of the search condition), a reasonable person would not view the consent to extend to a full search of his person and residence because the visit condition does not give authority to search. Also relevant is the fact that the visit condition requires the probationer to submit to visits not just of his home but of his place of employment, too. It is inconceivable that a probationer’s consent to .an employment visit would extend to a full search of his place of employment; because the visit condition draws no distinction between home visits and employment visits, a reasonable person would expect the same limits on officer conduct to apply to home visits as well.
The probation regulations (as distinct from the conditions) also reflect a significant difference betwéen searches and home visits. There is no mention of home visits in the search policy. See Corrections Policies 27-16-01. This absence is a telling indication that the Department of Corrections itself does not view home visits and searches as the same type of officer-probationer interaction. This reasoning is further supported by the “Supervision: Case Classification” policy, which sets out the types and number of contacts a probation officer must have with a probationer under his supervision. CORRECTIONS POLICIES 27-12-01. These requirements vary depending on the probationer’s “supervision classification.” Home visits are mandated for some levels of supervision. Id. ¶VI.A.1-2. The other types of contacts required within these same classifications are “[pjersonal [cjontacts in the office,” “[r]ec-ord [c]heek[s],” and “monthly verification *618 of employment.” 18 Id. Each of these contacts represents a minimal invasion of the probationer’s privacy. The inclusion of home visits (and the notable absence of searches) in this category of contacts strongly suggests that home visits, too, are meant to be minimally invasive.
In sum, taking the government’s factual allegations as true, Henry consented not to a contraband search but to a home visit to verify his address. In light of the probation conditions and regulations reviewed above, it is clear that consent to a home visit does not encompass consent to a full search. Officer McClish exceeded Henry’s consent by conducting a full search, 19 so the government has failed to carry its burden that the search was consensual.
Because the instant search was authorized by neither reasonable suspicion nor consent, the district court should have granted Henry’s motion to suppress.
B. Constitutionality of § 922(g)(1)
Section 922(g)(1) makes it “unlawful for any person ... who has been convicted in any court of[] a crime punishable by imprisonment for a term exceeding one year ... to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.” Henry appears to argue that in light of our recent decision in
Waucaush v. United States,
1. Failure to Raise Below
Henry did not raise his challenge to § 922(g)(1) below. “It is the general rule ... that a federal appellate court does not consider an issue not passed upon below.”
Pinney Dock & Transp. Co. v. Penn Central Corp.,
In
United States v. Chesney,
Application of these factors shows that there are exceptional circumstances here. Henry bases his argument on Waucaush, a case decided by this court after the district court entered judgment, such that the argument was unavailable below. Furthermore, the issue is — as it was in Chesney — purely a legal question that both parties have fully briefed. Therefore, we choose to exercise our discretion to decide whether the conviction was constitutional in light of Waucaush. 20
2. Merits
In
Waucaush,
the defendant and his fellow gang members murdered, conspired to murder, and assaulted, with intent to murder, members of rival gangs.
We explicitly held
post-Lopez
that a § 922(g)(1) conviction comports with the Commerce Clause so long as the defendant “possessed a gun that previously had moved in interstate commerce.”
Chesney,
*620
ney
relied heavily on the Supreme Court’s interpretation of the predecessor to § 922(g)(1).
Id.
at 571 (“The Supreme Court has held that proof that a firearm moved in interstate commerce at any time is sufficient to meet the government’s burden of proving the ‘in commerce or affecting commerce’ element of § 1202(a), the predecessor to § 922(g)(1).”) (citing
Scarborough v. United States,
Henry concedes that the government satisfied § 922(g)(l)’s jurisdictional element as interpreted by Chesney. Therefore, Henry’s conviction under § 922(g)(1) was constitutional.
III. CONCLUSION
For the reasons set forth above, we REVERSE the district court’s denial of Henry’s motion to suppress, VACATE Henry’s conviction and sentence, and REMAND the case for further proceedings consistent with this opinion.
Notes
. The district court appears to have credited Officer Havens's initial assertion on direct examination, J.A. at 80 (Suppression Hr'g Tr. at 8) (Havens Test.), that his second visit of October 13, 2003, was in the evening. J.A. at 69 (Mem. & Order at 2). This finding was clearly erroneous, because on both cross-examination and redirect examination, Officer Havens clarified that his second visit was in the afternoon. J.A. at 89 (stating that his second visit on “the 20th of October” — the context makes it clear that he actually was referring to the 13 th — was “in the afternoon”), 95 (answering that he "went once in the morning and once in the afternoon” when asked to state to “the best of [his] recollection” when he went on October 13th) (Suppression Hr'g Tr. at 19, 27) (Havens Test.). In any event, at oral argument the government conceded that the second visit was in the afternoon.
. It was later discovered that the firearm was not real.
. We need not address at length Henry’s third argument for suppressing the ammunition— that the search violated the Fourth Amendment because it was not executed in accordance with state regulations. We have explained that state law has no independent significance in determining whether the Fourth Amendment has been violated.
United States v. Wright,
. The regulation also set out "a variety of factors" that an officer "should consider ... in determining whether 'reasonable grounds' exist.”
Griffin,
. The Court revisited the issue of warrantless searches of probationers' residences, in the context of investigatory rather than probationary purposes, in
United States v. Knights,
. The Wisconsin regulation upheld in
Griffin
also was limited to searches for contraband.
. In
Payne,
we suggested a third step in the analysis. If a search is “not authorized by the regulatory scheme/' it is "unreasonable unless it independently satisfies traditional Fourth Amendment requirements.”
. We addressed a related issue in
United States v. Carnes,
. The Ninth Circuit has since characterized
Dally
as invoking the reasonable suspicion standard.
Moreno v. Baca,
. The Supreme Court said in
Illinois v. Wardlow,
Also supporting our conclusion in
loshua
is the fact that
Wardlow
itself involved evasion rather than mere nervousness.
See
. The Court instead considered the condition to be "a salient circumstance” in determining whether the reasonable-suspicion-based investigatory search of a probationer’s residence was reasonable.
Knights,
. The diversity of approaches reflects the difficulty of the issue. The Seventh Circuit has held that a probationer’s agreement to terms of probation that include a broad search condition constitutes effective consent.
United States v. Barnett,
.This court has addressed the issue only by unpublished opinion.
See United States v. Downs,
. It is the state corrections policies and procedures manual — not the probation conditions — that provides for searches not just for contraband possession but also for other probation violations, which presumably would include a residency violation. See J.A. at 57-58 (Corrections Policies 27-16-01 ¶VI.(1)). There is no evidence, however, that Henry agreed to or even saw this manual.
. Therefore, we need not consider the contradictions and holes in the officers' testimony, such as Officer Tally’s testimony that Henry did not give verbal consent and the officers’ failure to recall a fact as basic as whether Henry had a key to the house.
.Nor can the government complain that we must remand in order to permit it to put forth more facts on the consent issue. In his motion to suppress, Henry argued that the search was nonconsensual, J.A. at 28 (Mot. and Mem. to Suppress ¶ 4), and both parties elicited testimony relevant to the consent issue at the suppression hearing. "When, as here, it is alleged that the defendant consented to the search, ‘[i]t is the Government's burden, by a preponderance of the evidence, to show through 'clear and positive testimony’ that valid consent was obtained."
United States
v.
Haynes,
. We have applied the expressed-object principle to hold that consent to search a vehicle for contraband like drugs or stolen goods encompasses the vehicle’s gas tank.
Garrido-Santana,
. "Personal contacts” simply means "face to face contact between the [ojfficer and the offender.” Corrections Policies 27-12-01 ¶ IV.3. A "record check” is "a local record check which may be completed at the clerk’s office by reviewing printouts provided by local jails or court systems and using the administrative office of the courts automated system.” Id. ¶ IV.4. Verification of employment is not defined.
. There is no question that searching a bag is a full search and therefore exceeds the scope of consent, so we need not decide today exactly what officer conduct would fall within the scope of consent to a home visit.
. We do not read Henry's brief to also argue that § 922(g)(1) is unconstitutional on its face. In any event, we would decline to exercise our discretion to address such a challenge because Henry had ample opportunity to raise the argument below, in contrast to the as-applied issue, Henry points to no case decided subsequent to his conviction that has arguably disturbed our numerous precedents rejecting facial challenges to § 922(g)(1).
United States
v.
Sawyers,
. It appears that only the District of Columbia Circuit has not addressed the as-applied constitutionality of § 922(g)(1).
