Quote:I said it was sad that someone couldn't have stopped him after he had a gun,
Let's examine this one for a moment. So many states have made it legal to walk around packing heat that the sight has become common. That said, are you going to start shooting everyone else you see with a gun on the theory that they might be planning something nefarious instead of merely being gun nuts parading around because of their fucking rights? What will you do if they start shooting back? What will the cops do if they drive up to an active exchange between two "armed citizens?"
So you would need actual knowledge of an intent to commit a crime and, if you had that, why not simply call the cops instead of taking the law into your own hands?
