Defendant-Appellant James Baker appeals his conviction for being a felon in possession of ammunition, as well as his sentence. We are called upon to decide whether the jury should have been instructed on Mr. Baker’s proposed “innocent possession” defense to being a felon in possession of ammunition and whether 18 U.S.C. § 921(a)(20) of the Armed Ca*1323reer Criminal Act contemplates a “conviction-specific” approach to its application. We answer both questions in the negative.
I. BACKGROUND
At approximately 4:00 a.m. on November 1, 2005, James Baker was sitting in a car in a parking lot outside his stepdaughters’ apartment complex. Officer Richard Bachman of the Wichita, Kansas Police Department was patrolling the area and thought that the vehicle, which was parked with its lights on, looked suspicious. He turned his patrol car’s lights on the vehicle. As he did so, Mr. Baker got out of the car and approached the patrol car. Officer Bachman instructed Mr. Baker to stop moving and asked Mr. Baker for identification, which he provided. The dispatcher ran a routine records check on the vehicle, which revealed that the tag had been reported as lost or stolen. Based on this information, Officer Bachman detained Mr. Baker. The dispatcher then reported that a records check on Mr. Baker revealed the existence of two active city bench warrants for his arrest. Officer Bachman therefore arrested Mr. Baker. During a search incident to the arrest, Officer Bachman found a speed loader with six rounds of live ammunition in Mr. Baker’s pocket. It was later discovered that the ammunition had been stolen earlier that night during a burglary of Doc’s Steakhouse in Wichita.
Mr. Baker was charged in a two-count indictment with being a felon in possession of ammunition, in violation of 18 U.S.C. § 922(g)(1), and with possession of stolen ammunition, in violation of 18 U.S.C. § 922(j). He pleaded not guilty, and the case went to trial. During the trial, Mr. Baker testified that he saw the ammunition on the ground after leaving a Halloween party at an apartment complex. According to Mr. Baker, he picked up the ammunition so that he could turn it into the police; he did not want to leave it on the ground because he was worried that a child might find it. Before Mr. Baker drove to the police station, however, he and two other individuals drove to another apartment complex. He testified that he was sitting in the car in the complex’s parking lot when he saw Officer Bachman in the patrol car. Mr. Baker figured he could hand the bullets over to Officer Bachman rather than go to the police station, so he got out of the car and approached Officer Bachman, who had exited the patrol car. Officer Bachman immediately started questioning Mr. Baker about the reason he was in the parking lot, and before Mr. Baker could give him the bullets, Officer Bachman placed him under arrest and discovered the bullets. Mr. Baker also testified that he only had the ammunition for about ten minutes before he was arrested.
At the close of the evidence, Mr. Baker requested an “innocent possession” jury instruction. Specifically, he sought the following instruction:
It is a defense to the charge of unlawful possession of ammunition that the defendant’s possession of the ammunition constituted innocent possession. Possession of ammunition constitutes innocent possession where:
1. The ammunition was obtained innocently and held with no illicit purpose; and
2. Possession of the ammunition was transitory, i.e., in light of the circumstances presented there is a good basis to find that the defendant took adequate measures to rid himself of possession of the ammunition as promptly as reasonably possible.
If you find that the defendant possessed ammunition specified in Count 1 and Count 2 and that possession constituted innocent possession, you should find the defendant not guilty.
*1324The District Court concluded that the instruction was not warranted on the evidence presented and denied the motion. Following the two-day trial, the jury convicted Mr. Baker of being a felon in possession of ammunition, but acquitted him of possession of stolen ammunition. Mr. Baker moved for judgment of acquittal or a new trial, again arguing that he was entitled to a jury instruction on “innocent possession.” The District Court denied the motion.
The probation office prepared a presen-tence report (“PSR”) recommending that Mr. Baker be sentenced as an armed career criminal under 18 U.S.C. § 924(e) and § 4B1.4 of the U.S. Sentencing Guidelines (“Guidelines”) based upon the office’s determination that Mr. Baker had three pri- or convictions for violent felonies. Mr. Baker argued that he should not be sentenced as an armed career criminal, objecting to the characterization of one of his prior convictions as a “violent felony.” The District Court overruled Mr. Baker’s objection and adopted the recommendations of the PSR. Based upon a total offense level of 33 and criminal history category VI, the Guidelines recommended a sentencing range of 235 to 293 months’ imprisonment. The District Court concluded that a sentence within the advisory range was appropriate in this case and sentenced Mr. Baker to a term of 235 months. Mr. Baker now appeals both his conviction and his sentence, arguing that the District Court erred in refusing to give the jury an instruction on “innocent possession” and in sentencing him as an armed career criminal.1 We have jurisdiction under 28 U.S.C. § 1291, and we AFFIRM.
II. DISCUSSION
A. Innocent Possession
We review jury instructions de novo, asking whether, as a whole, the instructions accurately informed the jury of the issues and the governing law. United States v. LaVallee, 439 F.3d 670, 684 (10th Cir.2006). Importantly, a criminal defendant is entitled to a jury instruction on his theory of defense if that instruction is supported by the law and has some foundation in the evidence. United States v. Al-Rekabi, 454 F.3d 1113, 1121 (10th Cir.2006). For the reasons that follow, we conclude that Mr. Baker’s requested jury instruction is not supported by the law.
To obtain a conviction under § 922(g)(1), the government must prove beyond a reasonable doubt that (1) the defendant was previously convicted of a felony; (2) the defendant thereafter knowingly possessed ammunition; and (3) the possession was in or affecting interstate commerce. United States v. Ledford, 443 F.3d 702, 713 (10th Cir.2005). The government need not establish that the defendant possessed the contraband for any illicit purpose; the defendant’s motive for possessing ammunition is irrelevant to the crime. See United States v. DeSoto, 950 F.2d 626, 632 (10th Cir.1991) (explaining that motive for possessing a firearm is irrelevant to offense of being a felon in possession of a firearm); see also United States v. Gilbert, 430 F.3d 215, 218 (4th Cir.2005) (“The statute [§ 922(g)] in no way invites investigation into why the defendant possessed a firearm or how long that possession lasted.”); United States v. Reynolds, 215 F.3d 1210, 1214 (11th Cir.*13252000) (“Section[ ] 922(g) ... do[es] not focus on the motive or purpose of the current possession of firearms.”). In fact, we have previously characterized federal firearms laws as imposing “something approaching absolute liability.” United States v. Adkins, 196 F.3d 1112, 1115 (10th Cir.1999) (quotation omitted).
Mr. Baker argues, however, that his motive in possessing the ammunition is (or should be) relevant to the crime charged. Specifically, he contends that if a defendant obtains ammunition innocently, with no illicit purpose, and takes adequate measures to rid himself of it as promptly as reasonably possible, he cannot be convicted under § 922(g). As support for this contention, Mr. Baker cites United States v. Mason, 233 F.3d 619 (D.C.Cir.2000), in which the D.C. Circuit recognized the “innocent possession” defense and applied it to facts similar to those in the present case.
In Mason, the defendant (a felon) testified that he found a gun in a bag while working as a delivery driver. Id. at 621. He claimed he picked up the bag and gun because he was near a school and there were children around. Id. He then drove to the Library of Congress, his next delivery stop, where he intended to turn the gun over to a police officer he knew. Id. As the defendant was entering the building, however, another officer saw the gun and arrested the defendant. Id. The court of appeals held that the district court should have instructed the jury on the innocent possession defense. Id. at 625. Specifically, the court held that the defense is available when the record reveals that:
(1) the firearm was attained innocently and held with no illicit purpose and (2) possession of the firearm was transitory — i.e., in light of the circumstances presented, there is a good basis to find that the defendant took adequate measures to rid himself of possession of the firearm as promptly as reasonably possible.
Id. at 624. It reasoned that absent such a defense, “a felon-in-possession always will be guilty once he knowingly possesses a weapon, without regard to how or why he came into possession or for how long possession was retained.” Id. at 623.
In our view, however, that is precisely what Congress envisioned by prohibiting knowing, as opposed to willful, possession of ammunition. See United States v. Reed, 114 F.3d 1053, 1057 (10th Cir.1997) (a conviction under § 922(g) requires knowing possession). In criminal law, “knowing” possession simply requires proof of knowledge of the facts that constitute the possession, whereas a requirement of willfulness generally requires that the defendant act with a “bad purpose.” Bryan v. United States, 524 U.S. 184, 191, 193, 118 S.Ct. 1939, 141 L.Ed.2d 197 (1998); United States v. Gilbert, 430 F.3d 215, 218-19 (4th Cir.2005). In other words, by prohibiting knowing possession, the statute does not invite inquiry into the reason the defendant possessed the ammunition, as long as the defendant knew it was ammunition he possessed. See Adkins, 196 F.3d at 1115 (stating that § 922(g) imposes criminal liability on a felon in possession of a firearm “unless that felon truly did not know that what he possessed was a firearm”).
We acknowledge that this Circuit has recognized the availability of a necessity defense, which does permit inquiry into the circumstances under which a felon possesses contraband. To prevail on the necessity defense, the defendant must show that “(1) there is no legal alternative to violating the law, (2) the harm to be prevented is imminent, and (3) a direct, causal relationship ... exist[s] between defendant’s action and the avoidance of harm.” *1326Al-Rekabi, 454 F.3d at 1121 (quotation omitted).2 The purpose of requiring the defendant to show that he had no legal alternative to violating the law “is to force an actor to evaluate the various options presented and choose the best one” because “[i]n most cases, there will be a clear legal alternative.” Id. at 1123. Mr. Baker’s requested instruction does not require that the felon contemplate legal options prior to taking contraband into possession. To permit such an instruction would expand the necessity defense and contravene the rule that the defense be “strictly and parsimoniously applied.” Id. at 1122. In addition, we acknowledge that the Supreme Court has called into question the validity of the narrower necessity defense. See United States v. Oakland Cannabis Buyers’ Co-op., 532 U.S. 483, 490, 121 S.Ct. 1711, 149 L.Ed.2d 722 (2001) (“We note that it is an open question whether federal courts ever have authority to recognize a necessity defense not provided by statute.”). We therefore decline to expand this defense.
Mr. Baker suggests, however, that even under our existing case law, the facts of his case do not amount to a crime. We disagree. In United States v. Santistevan, 39 F.3d 250, 255 (10th Cir.1994), this Court addressed whether distribution of drugs under 21 U.S.C. § 841(a)(1) requires “concrete involvement” in the distribution. In refusing to read a “concrete-involvement” requirement into the clear statutory definition of “distribution,” we explained:
[I]f the “concrete involvement” language is being used as a means of separating “true” criminal acts from other situations, such as an undercover police officer who transfers drugs to an unsuspecting buyer during the course of a sting operation, or the “Good Samaritan” private citizen who finds drugs on the street and takes them to the police station, we believe the “concrete involvement” language is an inappropriate vehicle. [Title 21 U.S.C. § ] 841(a)(1) would, if read literally, criminalize the two situations described above. While that result may seem absurd, the conclusion that Congress in fact intended this result is bolstered by the enactment of statutes like 21 U.S.C. § 885, which confers an immunity to an individual like an undercover officer who handles controlled substances during the course of his official duties. If Congress did not intend to criminalize this type of conduct because there is no evidence of any “concrete involvement,” then § 885 seems unnecessary. Moreover, while § 841(a)(1) might literally extend to an individual who finds drugs on the street and brings them to a police station, we believe adequate protection exists in the sound exercise of prosecutorial disere*1327tion, rather than requiring any type of nebulous “concrete involvement” in the criminal undertaking.
Id. at n. 7; see also Al-Rekabi, 454 F.3d at 1126 (“If events actually transpired as [the defendant] described them and he had given up his control over the pistol by securing it and alerting the police, it is unlikely he would even have been charged.”).
Far from recognizing that being a “Good Samaritan” is a defense to criminal liability, we acknowledged in Santistevan that Congress in fact intended § 841(a)(1) to encompass a situation in which a person brings innocently found drugs to a police station. See Santistevan, 39 F.3d at 255 n. 7. We reasoned that if the safeguard against liability for being a Good Samaritan is not provided by statute, it is found in the exercise of sound prosecutorial discretion. Id. We apply the same rationale today and therefore decline to recognize Mr. Baker’s proposed “innocent possession” defense when Congress could have created the defense had it seen fit to do so. See United States v. Johnson, 459 F.3d 990, 996-97 (9th Cir.2006) (declining to adopt an innocent possession defense to liability under § 922(g), stating that “Congress knows how to create an affirmative defense when it wishes to do so” and listing affirmative defenses provided by statute). In so doing, we join two of our sister circuits that have refused to create an innocent possession defense on facts similar to those at issue here. See id. at 998; Gilbert, 430 F.3d at 220; see also United States v. Teemer, 394 F.3d 59, 64-65 (1st Cir.2005) (declining to adopt the innocent possession defense discussed in Mason); United States v. Hendricks, 319 F.3d 993, 1007 (7th Cir.2003) (refusing to expand the necessity defense to encompass innocent possession). Because Mr. Baker’s requested instruction is not supported by law, the District Court did not err in declining to give it.3
B. Application of the Armed Career Criminal Act
The Armed Career Criminal Act (“ACCA”) enhances a sentence to a mandatory minimum of fifteen years for a felon convicted of possessing ammunition when the felon “has three previous convictions ... for a violent felony or a serious drug offense.” 18 U.S.C. § 924(e)(1). A “violent felony” includes a burglary “punishable by imprisonment for a term exceeding one year.” See id. § 924(e)(2)(B)(ii). The ACCA exempts, however, certain convictions for which a person has had his civil rights restored:
What constitutes a conviction of [a crime punishable by imprisonment for a term exceeding one year] shall be determined in accordance with the law of the jurisdiction in which the proceedings were held. Any conviction which has been expunged, or set aside or for which a person has been pardoned or has had civil rights restored shall not be considered a conviction for purposes of this chapter, unless such pardon, expungement, or restoration of civil rights expressly provides that the person may not ship, transport, possess, or receive firearms.
18 U.S.C. § 921(a)(20) (emphasis added).
In 1997, 1999, and 2003, Mr. Baker was convicted of burglary under Kansas law and sentenced to more than one year’s imprisonment for each conviction. Based *1328on these three convictions, the District Court concluded that Mr. Baker was an armed career criminal. Mr. Baker contends that his 1997 conviction cannot be counted as a predicate offense under the ACCA because he had his civil rights restored as to this conviction under Kansas law.
We review de novo an issue of statutory interpretation involving the ACCA. United States v. Burns, 934 F.2d 1157, 1159 (10th Cir.1991). A defendant’s civil rights have been restored under state law for purposes of § 921(a)(20) if the state has also restored the defendant’s right to possess firearms. See id. at 1160 (concluding that defendant did not have his civil rights restored because defendant did not have the right to possess firearms); see also United States v. Dockter, 58 F.3d 1284, 1290 (8th Cir.1995) (explaining that “for a person to have his civil rights restored by a state for the purposes of section 921(a)(20), the relevant state must actually have restored the felon’s right to possess firearms.” (quotations omitted)). Under Kansas law, release from parole or imprisonment has the effect of “restoring all civil rights lost by operation of law upon commitment,” Kan. Stat. Ann. § 22-3722, including eligibility “to hold any public office ..., to register as a voter or to vote in any election ... or to serve as a juror in any civil or criminal case,” id. § 21-4615(1). But § 22-3722 does not say anything about a felon’s right to possess firearms. If taken in isolation, § 22-3722 would indicate that once a felon has been released from parole or imprisonment, the underlying offense cannot be used as a predicate offense for sentencing under the ACCA. See 18 U.S.C. § 921(a)(20) (stating that a conviction is not considered a violent felony if the defendant has had his civil rights restored “unless such ... restoration of civil rights expressly provides that the person may not ship, transport, possess, or receive firearms” (emphasis added)).
In this Circuit, however, to determine whether state law expressly restricts a felon’s right to possess firearms, we “look to the whole of state law.” Burns, 934 F.2d at 1160 (consulting provisions of the Kansas criminal code to determine a felon’s right to possess a firearm).4 And in Kansas, release from parole or imprisonment does not automatically restore the right to possess a firearm. Rather, Kansas criminalizes possession of a firearm “by a person who, within the preceding five years has been convicted of a felony ... [or] has been released from imprisonment for a felony.” Kan. Stat. Ann. § 21-4204(a)(3). Under this statute, Mr. Baker has not had the right to possess a firearm since his first burglary conviction in 1997. His sentence for the 1997 burglary conviction was discharged on May 13, 1999. Under § 21-4204(a)(3), he was prohibited from possessing firearms until May 13, 2004. Before that date, however, on March 9, 1999, Mr. Baker was convicted of his second burglary. His sentence for that offense was discharged on December 13, 2002. He was thus continuously prohibited from possessing firearms from the 1997 conviction until December 13, 2007.
Mr. Baker argues, however, that 18 U.S.C. § 921(a)(20) is “conviction specific,” *1329and we should therefore look to each conviction in isolation to determine whether he had his right to possess a firearm restored with respect to that particular conviction. In this way, he contends that his right to possess a firearm as to the 1997 burglary conviction was automatically restored on May 13, 2004, five years after his sentence for that crime was discharged— notwithstanding the fact that he was incarcerated at that point for another felony and, accordingly, was under another firearms restriction for that conviction.
We addressed a related question in United States v. Burns, 934 F.2d 1157 (10th Cir.1991). In that case, the defendant pleaded guilty to three counts of burglary under Kansas law in 1965. Id. at 1158. He received a certificate of discharge from Kansas for those offenses in September 1981 while he was imprisoned for several unrelated forgery and drug offenses. Id. The certificate purported to restore the defendant’s civil rights, “including but not limited to the right to vote, the right to hold public office, and the right to serve on a jury.” Id. He was released from custody on the forgery and drug offenses in September 1984. Id. He was arrested again, however, in December of that year and remained incarcerated until March 1986. Id. One year later, he pleaded guilty to the federal offense of being a felon in possession of a firearm. Id.
The defendant argued against application of the ACCA, contending that his burglary convictions in 1965 could not be considered violent felonies under § 921(a)(20) because the certificate of discharge restoring his civil rights did not state that he could not possess a firearm. Burns, 934 F.2d at 1159; see also 18 U.S.C. § 921(a)(20). We rejected that argument because, “looking to the whole of state law,” the defendant was continuously subject to the firearms disability found in Kan. Stat. Ann. § 21-42045 up to the time of the felon-in-possession offense; that is, there was never a five-year period between the time he was discharged from the burglary convictions and the time he was convicted for being a felon in possession that he was not in prison for a felony. Burns, 934 F.2d at 1160-61. Thus, “[h]is right to possess a firearm was never effectively restored.” Id. at 1161. As a result, the burglary convictions could be used to enhance the defendant’s sentence under the ACCA. Id. at 1160-61.
Bums stands for the proposition that the defendant must actually have the right to possess firearms restored to him before an otherwise-qualifying conviction is not considered a violent felony for purposes of § 924(e). Indeed, two of our sister circuits relied on Bums in explicitly rejecting the approach urged by Mr. Baker. See United States v. Dockter, 58 F.3d 1284, 1291 (8th Cir.1995) (“/AJctual restoration of the right to possess firearms [is required] in order for a conviction to be excludable under § 921(a)(20).” (emphasis added)); United States v. Clark, 993 F.2d 402, 405 (4th Cir.1993) (“We hold ... as a matter of federal law that a state conviction for a violent felony is not excluded from consideration under § 924(e) by the provisions of § 921(a)(20) until the law of the relevant state effectively restores to the defendant the right to possess firearms.” (emphasis added)). We agree with *1330these circuits, and we now hold that when state law has continuously prohibited a defendant from possessing a firearm, the state has not effectively restored the defendant his civil rights and therefore each of the defendant’s otherwise-qualifying convictions constitutes a violent felony under § 924(e).
In this case, since his first burglary conviction in 1997, Mr. Baker has not been out of state custody for a period of five years between felony convictions. Thus, his right to possess a firearm was never effectively restored as to the 1997 burglary, and the District Court properly considered it a violent felony under § 924(e). The District Court therefore did not err in enhancing his sentence.
III. CONCLUSION
Because we conclude that “innocent possession” is not a defense to being a felon in possession of ammunition, we conclude that the District Court did not err in refusing to tender such an instruction. Accordingly, we AFFIRM Mr. Baker’s conviction. In addition, because we conclude that Mr. Baker never had his right to possess firearms effectively restored under Kansas law, the District Court properly concluded that his 1997 burglary conviction is a violent felony for purposes of the ACCA. Accordingly, we AFFIRM Mr. Baker’s sentence.
. Mr. Baker raises two other arguments on appeal: (1) 18 U.S.C. § 922(g)(1) is an unconstitutional exercise of Congress’s authority under the Commerce Clause; and (2) because Mr. Baker is permitted to possess ammunition under state law, he should not be prohibited from doing so under federal law. Mr. Baker candidly admits that Supreme Court and Tenth Circuit precedent forecloses these arguments, and he seeks merely to preserve the issues for further review. We acknowledge that he has done so.
. We have also discussed, but never explicitly recognized, a "fleeting possession” defense, which requires proof that the defendant "(1) merely momentarily possessed the contraband, and (2) either lacked knowledge that he possessed contraband or had a legally justifiable reason to possess it temporally.” Al-Rekabi, 454 F.3d at 1127 n. 16 (quotations and alterations omitted). Arguably, the reason this Court has never adopted such a defense is because a defendant who establishes the elements of fleeting possession necessarily proves the elements of the necessity defense. Id. at 1126. Having a “legally justifiable” reason to possess contraband temporarily requires proof that the defendant had "no reasonable legal alternative ... given the circumstances,” thus making this aspect of the fleeting possession defense redundant to the necessity defense. Id. at 1126. And proof that a defendant lacked knowledge that he possessed contraband is not part of an affirmative defense because it negates an element of the crime itself. See id. at 1127 n. 16; see also Adkins, 196 F.3d at 1115 (stating that § 922(g) imposes criminal liability on a felon for possession of a firearm for "a mere second or two unless that felon truly did not know that what he possessed was a firearm”).
. United States v. Herron, 432 F.3d 1127 (10th Cir.2005) is not to the contrary. In that case, the defendant sought and obtained from the district court the instruction Mr. Baker requests here. On appeal, however, we did not address whether an innocent possession instruction was supported by law. The issue was whether the prosecutor improperly informed the jurors that they could disregard the innocent possession instruction.
. We note a split in the circuits regarding whether a court may look only to a certificate of restoration of civil rights upon release from parole or imprisonment to decide whether the certificate expressly limits a felon's right to possess firearms, or whether, as in this Circuit, we may look to the whole of state law to make such a determination. See United States v. Chenowith, 459 F.3d 635, 638 (5th Cir.2006) (noting that the Fifth, Seventh, and Ninth Circuits adhere to the former approach, while the Fourth, Sixth, and Tenth Circuits adhere to the latter approach).
. Bums interpreted an older, but similar, version of the same statute at issue in this case. See Kan. Stat. Ann. § 21-4204(l)(b) (1991) (providing that "[u]nlawful possession of a firearm is ... possession of a firearm with a barrel less than 12 inches long by a person who, within five years preceding such violation has been convicted of a felony under the laws of Kansas or any other jurisdiction or has been released from imprisonment for a felony”).
