OPINION OF THE COURT
Terrell Polk appeals from an order sentencing him to 37 months’ imprisonment for possession of a “shank” in prison. The District Court characterized Polk’s offense as a “crime of violence,” and accordingly calculated his sentencing range pursuant to the Career Offender Guidelines. This was correct under
United States v. Kenney,
I. Background
In June 2007, Polk, an inmate serving a sеntence at the United States Penitentiary at Lewisburg, PA, had his cell searched by a correctional officer, who found a six-inch plastic homemade shank in an envelope containing his personal papers. A grand jury in the Middle District of Pennsylvania returned a one-count indictment against Polk for possession of a prohibited object designed to be used as a weapon in violation of 18 U.S.C. § 1791(a)(2), and Polk pleaded guilty to the indictment in accordance with a plea agreеment. At Polk’s sentencing hearing in December 2008, the District Court determined that the offense qualified as Polk’s third predicate “crime of violence,” thus warranting a three-level sentence enhancement under the federal Sentencing Guidelines for career offenders. U.S.S.G. § 4B1.1. Consequently, Polk’s total offense level was 14, which, when combined with his criminal history category of VI, resulted in a Sentencing Guidelines range of 37-A6 months. Without the enhancement, the Guidelines range would have been 27-33 months. Polk did not objeсt to his designation as a career offender (though Begay had been issued six months before sentencing), and, as noted, was sentenced to 37 months’ imprisonment. He timely appealed.
II. Jurisdiction and Standard of Review
The District Court had jurisdiction under 18 U.S.C. § 3231. We have jurisdiction under Í8 U.S.C. § 3742(a)(1) and 28 U.S.C. § 1291.
Because Polk did not object to his designation as a career offender for sentencing purposes in the District Court, we review for plain error. Fed.R.Crim.P. 52(b). To grant the relief requested under this standard, we would need to conclude not only that the District Court errеd in classifying Polk as a career offender, but that the error was plain, and it affected adversely “substantial rights” of Polk as well as the “fairness, integrity, or public reputation of judicial proceedings.”
United States v. Davis,
If we determine the error was not plain, Polk’s сounsel offers an alternative argument of ineffective assistance of counsel based on his failure to raise
Begay
and its arguable effect at sentencing. Under
Strickland v. Washington,
III. Discussion
A.
Polk аrgues that his § 1791(a)(2) conviction cannot serve as a predicate “crime of violence” for the purpose of designating him as a career offender. Under the Career Offender Guidelines, a “crime of violence” is defined as
any оffense under federal or state law ... that — (1) has as an element the use, attempted use, or threatened use of physical force against the person of another, or (2) is burglary of a dwelling, arson, or extortion, involves the use of explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another.
U.S.S.G. § 4331.2(a).
In
Kenney,
we held that “whatever an inmate’s intentions!,] his possession of a weapon in a prison inherently, and accordingly ‘by its nature,’ presents ‘а serious potential risk of physical injury’ to other persons in the prison.”
In
Begay,
the Supreme Court addressed the “violent felony” provision of the Armed Career Criminal Act (ACCA).
any crime ... that — (i) has as an element the use, attempted use, or threatened use of physical force against the person of another; or (ii) is burglary, arson, or extortion, involves the use оf explosives, or otherwise involves conduct that presents a serious potential risk of physical injury to another....
18 U.S.C. § 924(e)(2)(B). The Court held that, to qualify as a “violent felony” under the “otherwise involves” clause of this provision, an offense must (1) present a serious potential risk of physical injury
and
(2) be “roughly similar, in kind as well as degree of risk posed, to the examples [burglary, arson, extortion, or use of explosives] themselves.”
Begay,
The question we face is whether
Begay’s
analysis — that offenses must involve “purposeful, violent, and aggressive conduct” to qualify as a “violent felony” for ACCA purposes — also applies to the Career Offender Guidеlines.
Pre-Begay,
our Court stated that though the language of the ACCA’s “violent felony” provision is nearly identical to the Career Offender Guidelines’ definition of a “crime of violence,” these two sections are not necessarily coextensive.
United States v. Parson,
Given Begay’s applicability to the offense at issue here, we hold that possession of a weapon, even in a prison, is not “roughly similar, in kind as well as in degree of risk posed,” to the enumerаted crimes of burglary, arson, extortion, or use of explosives.
Post
-Begay,
the distinction between active and passive crimes is vital when evaluating offenses under the Career Offender Guidelines to determine if they entail “purposeful, violent, and aggressive conduct.” Wfliile possessing a weapon in prison is purposeful, in that we may assume one who possesses a shank intends that possession, it cannot properly be characterized as conduct that is itself aggressive or violent, as only the potential exists for aggressive or violent conduct. Much like carrying a concealed weapon, the offense is a “passive crime centering around
possession,
rather than around any overt action.... The act of possession does not, without more ..., involve any aggressive or violent behavior.”
United States v. Archer,
The Government urges us, in analyzing the nature of Polk’s offense, to emphasize that his possessory crime occurred in a prison context, аn environment in which heightened security is required and no permissible use exists for a prisoner to possess a weapon. That was the basis of our analysis in
Kenney,
*520
Begay
excludes that mode of analysis, however. We do not dispute the inherent dangers of possessing a shank in prison, but this alone cannot transform a mere possession offense into one that is similar to the crimes listed. Thus, a § 1791(a)(2) conviction for possession of a prohibited object designed to be used as a weapon in prison is not a “crime of violence” for purposes of the Career Offender Guidelinеs. We recognize that our decision is at odds with the Tenth Circuit Court’s recent decision in
United States v. Zuniga,
B.
The District Court erred in sentencing Polk as a career offender, but becаuse he did not object at sentencing, the fact that it was an error is not enough for us to grant the relief requested. The existence of the Tenth Circuit Court’s Zuniga decision, from which a district court could reasonably conclude that our Kenney analysis was still sound after Begay, makes us disinclined to conclude that the District Court’s error here was plain. However, it is not necessary to determine if the error was plain in this instance, because we agree with the argument of Polk’s attorney that he (the attorney) was ineffective at sentencing based on his failure to raise Begay and its arguable effect.
Defendants are not generally permitted to attack the efficacy of their counsel on direct appeal, though an exception will be made “[wjhere the record is sufficient to allow determination of ineffective assistance of counsel, [and thus] an evidentiary hearing to develop the facts is not needed.”
United States v. Headley,
‡ H* # H< H* Hí
As Kenney no longer remains good law and possession of a weapon in prison should not be considered a “crime of violence” under the Career Offender Guidelines post-Begay, we vacate the District Court’s order and remand for resentencing consistent with this opinion.
Notes
. We need not decide whether and to what extent our decision in
Parson
remains effective after
Begay.
It is sufficient here to recognize that, though
Parson
says the definitions of "violent felony” and "crime of violence” in the ACCA and the Career Offendеr Guidelines, respectively, are not coextensive,
Begay
and the remands from the Supreme Court that have followed it indicate that the definitions are close enough that precedent under the former must be considered in dealing with the latter.
See, e.g., United States v. Stinson,
. We emphasize that we are not opening the door to ineffective assistance of counsel claims on direct appeal as a matter of course. We are, rather, dealing with a very unusual case here, in which there is a Supreme Court decision thаt represents a marked change in the law and, in addition, there is an adequate record involving highly competent and respected defense counsel freely acknowledging that his failure to cite that important new case had nothing to do with a strategic decision but was simply an oversight.
