Look lets don't get fact mixed up with stupid. Timothy Harper did this to himself. He earned whatever will happen to him. Unfortunately its the rest of us that will pay for his indiscretion. These morons who seek to stir up trouble almost always find it. He would have eventually killed someone or.... gotten arrested himself. Its fortunate; (in my opinion), that it was the latter.
I'm a little surprised some well intentioned citizen eating with his family didn't smoke his ass when he walked into the restaurant with his AR slung. People are getting a little worn out by being targets for madmen.
