Beckles v. U.S.

Whether Johnson v. U.S. applies retroactively to collateral cases challenging federal sentences enhanced under the residual clause in U.S.S.G. § 4B1.2(a)(2)? 2. Whether Johnson's constitutional holding applies to the residual clause, thereby rendering challenges to sentences enhanced under it cognizable on collateral review? Whether mere possession of a sawed-off shotgun, an offense listed as a "crime of violence" only in the commentary to U.S.S.G. § 4B1.2, remains a "crime of violence" after Johnson?
