United States v Gonzalez-Tamariz, 310 F3d 1168 (9th Cir 2002) (no error in applying 16-level enhancement to sentence for illegal re-entry because battery causing substantial bodily harm meets federal definition of aggravated felony regardless of state law label as a misdemeanor, and aggravated felony definition plainly provides that a crime of violence is an aggravated felony when the term of imprisonment is at least one year)
