AGGRAVATED FELONY - CRIME OF VIOLENCE

Laws 750.81d(1) ("assaults, batters, wounds, resists, obstructs, opposes, or endangers a person whom the individual knows or has reason to know is performing his or her duties."), is not a crime of violence for purposes of the Armed Career Criminal Act, since obstructing does not contain an element of force or create a substantial risk that force will be used in committing the offense).

Hoang v. Holder, ___ F.3d ___, 2011 WL 1885989 (9th Cir. May 17, 2011) (Washington conviction of misdemeanor rendering criminal assistance in the second degree, to a person who committed a felony, by providing such person transportation, in violation of Wash. Rev. Code 9A.76.080, did not categorically constitute an aggravated felony crime related to obstruction of justice under INA 101(a)(43)(S), 8 U.S.C. 1101(a)(43)(S), because a person could be convicted of violating this statute if to one whom s/he provided transportation s/he knows has committed a crime, before any investigation or judicial proceeding has begun; generic federal obstruction of justice requires that defendant commit an act involving either active interference with proceedings of a tribunal or investigation, or action or threat of action against those who would cooperate with the process of justice.); quoting Matter of Espinoza"Gonzalez, 22 I. & N. Dec. 889, 893 (BIA 1999) (en banc).

July 10, 2008) (federal conviction of failure to appear, in violation of 18 U.S.C. 3146, is broader than the aggravated felony definition of failure to appear, under INA 101(a)(43)(T), since 18 U.S.C. 3146 can be violated by failing to appear for a misdemeanor, for reasons other than to dispose of a charge, and based upon orders other than those issued by a court).
