In a fairly unsurprising determination, the Eleventh Circuit determined that a violation of 18 U.S.C. § 2422(b), which prohibits knowingly persuading, inducing, enticing, or coercing a minor to engage in sexual activity, is a crime of violence under federal sentencing laws.  "Since the conduct encompassed by the elements of §2422(b) involves a sex crime against a minor, the ordinary or generic violation of § 2422(b) involves a substantial risk the defendant may use physical force in the course of committing the offense."  As such, it it qualifies as a crime of violence under 18 U.S.C. § 16(b).  For the same reasons, a conviction under this statute is certainly a crime of violence for immigration purposes.
