Hey - it really would be a great 2nd Amendment case, right? Guy possesses an illegal weapon with absolutely no intent to use it, gets prosecuted.
I really hope Gregory gets charged and fights this on 2nd Amendment grounds. Then we can reach the Supreme Court with the clear question of whether you can make it illegal to possess a 30-bullet clip. Then we will have some real idea of how broad the right to bear arms is!
(I know he has a 1st Amendment defense here, but I am hoping he would waive that).
