A few comments:
1) Most of the recent mass shootings have occurred in gun-free zones.
2) Do we actually need more gun control laws or should we more effectively enforce the laws we already have?
3) Alcohol, drugs, tobacco, and cars are far deadlier and we do not ban any of them.
4) Why is a segment of the population so willing to give up their right that has been GUARANTEED (and not granted) by the government?
