To paraphrase Ted Nugent, "It was not too many guns that caused the massacre by Cho Seung-Hui at Virginia Tech, it was too few guns."
I have to agree. If just one person who was in the building had been carrying a gun, perhaps they would have dropped this loser.
A "No Gun Zone" are an invitation for wackos to walk in and start shooting. These guys are cowards and they choose these places because they know there will not be any opposition.
If he knew someone might have had a gun, maybe he would have had second thought, or maybe not. There is no way to tell.
One thing I do know is that if just one person had a gun, fewer people would have died. In addition, this loser might have been killed a bit sooner.
If someone would have had a gun, LIVES WOULD HAVE BEEN SAVED.
Any person that cannot see that is blind in one eye and can't see out of the other.
