Nguyen v. Holder, 571 F.3d 524 (6th Cir. Jul. 2, 2009) (California conviction of auto theft, in violation of what is now codified at Penal Code 487(d)(i) (any person who (1) takes possession; (2) of an automobile; (3) owned or possessed by another; (4) by means of trespass and (5) with intent to permanently deprive the owner of such property; and (6) carries the automobile away), does not constitute a "crime of violence" under 18 U.S.C. 16(b), and is therefore not an aggravated felony under INA 101(a)(43)(F), 8 U.S.C. 1101(a)(43)(F), for purposes of rendering the defendant deportable, because the theft offense does not by its nature, involve a "substantial risk" that physical force against the person or property of another may be used in the course of committing the offense).
