If half of the students at Virginia Tech (VT) were armed do you think it would have had the same outcome? If some student would have had the right to carry a gun that person or persons could have lessened this toll, even if that person would have used a gun haphazardly. But then again to get a concealed carry permit in Virginia you have to have a course in handling a firearm and a criminal background check. But still, they would not have been able to carry it at Virginia Tech because of the gun control that already exists. It's still illegal even with a permit to carry a gun on school grounds.
So we're back to our UK syndrome after all, we have a place (VT) where firearms are outlawed and we find that only the outlaw was able to have the gun. No one on the school was LEGALY able to have a gun to defend themselves.
So you tell me, here's a tragic example of gun control in action, does gun control work?
