United States v. Salas, 889 F.3d 681 (May 4, 2018).

On appeal from a conviction and sentence under 28 U.S.C. § 924(c), the Tenth Circuit held, as a matter of first impression, that the residual clause in the definition of “crime of violence” is unconstitutionally vague.  That clause refers to “a felony that by its nature, involves a substantial risk that physical force against the person or property of another may be used in the course of committing the offense.”
