IMO, he did the right thing. He heard screaming and gunshots and ran towards it. Thats what I call bravery. Think about it, those gunshots coulda been from anything. He didn't know if it was some nut like in the VT shootings or if it was some sorta terrorist attack. By grabbing his firearm, he prepared himself for whatever danger he or anyone else in the area was in. If this guy or someone like him was @ the VT shootings, I feel that it wouldn't of gone so far...I also hope that he wins his lawsuit.
