Voted NO.

I did a paper about this sort of topic in college. According to the informationI found at that time the majority of guns used in crimes are illegally purchased and sold thru the black market from places like China, Korea, etcand come in on ships that the government is not willing to police. They are usually off name weapons bought for cheap. Not purchased at your local gun shop.

Unfortunetly, someone does something with legally purchased weapons and people that are not informed start screaming to enforce tougher laws with no clear direction or thought on what you could actually do to prevent this from happening again.
