Matter of Velazquez-Herrera, 24 I. & N. Dec. 503, ___ (BIA May 20, 2008) (broad statutory purposes cannot carry interpretation past the language of the statute: "Thus, while we agree with the DHS that Congress intended section 237(a)(2)(E)(i) to be construed broadly, the statute's general purpose cannot supersede its language, which plainly focuses on those crimes of which an alien has been "convicted." We note in this regard that Congress's broad, enforcement-oriented purposes have not prevented courts from determining that other criminal grounds of deportability are subject to the categorical approach. See, e.g., Gonzales v. Duenas-Alvarez, 127 S. Ct. at 818 (discussing the applicability of the categorical approach in the context of a "theft offense" aggravated felony); Medina v. Ashcroft, 393 F.3d 1063, 1065-66 (9th Cir. 2005) (applying the categorical approach in the context of a "controlled substance violation" under section 237(a)(2)(B)(i) of the Act); United States v. Baron-Medina, 187 F.3d 1144, 1146 (9th Cir. 1999) (applying the categorical approach in the context of a "sexual abuse of a minor" aggravated felony).").
