I've been using the term "asswipe", but this works:
Another benefit is that, by not showing the face or the name of the asshole, asshole's attorneys can't claim "pretrial publicity" in a change-of-venue motion.
The only exception to the "some asshole" rule ought to be if the asshole is still at large. Then they could print his photo. But it'd have to come down once asshole was either dead or arrested.
