Sure. Just as I can find ACLU lawyers here on FR.
What's your point?
A DA can charge anyone with anything. That certainly doesn't support your contention that painting "INS" on one's vehicle is against the law.
If I can find a D.A. to charge it, it could definitely be against law - there's always jury nullification, but you probably didn't like that when O.J. walked, right?
Paint ICE on it and say you're selling ice. Three letter acronyms are better than four letters - ask the FBI, CIA, DOE and the BATFE.
