I see nothing wrong with him shooting them.  In many states, he was within his rights to do so.

Personally, if me or mine are in danger, I will do what is necessary to protect them.

I dont see anything wrong with shooting them either. Im just saying put me in that situation and the second i walked out the door and noticed some punks shot my dog they would all be dead. Im saying i dont own a gun because i dont have the restraint he had and i think that could get me in trouble.
