Today, the First Circuit examined whether Maine's gross aggravated assault statute, which criminalizes engaging in a sexual act with a victim under the age of 14, qualifies as a crime of violence under the federal law sentencing law.

This implies that the conviction would likely be considered a crime of violence under 8 USC 16(b), which defines crimes of violence of immigration purposes.
