Only in "non-CCW" states. In states that allow CCW, there might be an armed person almost anywher except where specifically prohibited (like schools!!!!). Case in point was the recent shootings in a Washington (state) mall. Unfortunately, this dumbass gun-owner HELD HIS FIRE because the shooter was a juvenile, got shot for his trouble, and is now paralyzed. He should have just SHOT the little bastard.
FBI spokesman Richard Kolko in Washington said there was no evidence to suggest it was a terrorist attack, "but all avenues will be explored."
How quickly they jump on that phrase.
