Lamb v. United States

Issue: (1) Whether the categorical approach, as detailed in Mathis v. United States, requires courts to determine whether an alternatively phrased statute presents alternative means or alternative elements; and whether, pursuant to this analysis, Michigan"s unarmed robbery statute is indivisible and overbroad because it does not require violent force, and therefore does not qualify as a predicate prior conviction under the Armed Career Criminal Act, 18 U.S.C. § 924(e)(1); and (2) whether, pursuant to Mathis, Wisconsin"s burglary statute is broader than generic burglary and therefore does not qualify as a predicate prior conviction under the ACCA.
