Immediately, I noted three major problems with this line of thinking. Obviously these are common sense for most of us and shouldn't need to be discussed. Criminals can still murder without firearms. To commit homicide, all that is required is an evil conscience. If guns are somehow removed from their hands, they will have no trouble adapting.
Violent criminals represent a relatively small percentage of the population.
No illness has ever been corrected by curing the symptom. Gun Control does just that. Some of our politicians seem to want to take this route. This tactic is a proven failure. Obviously, anything that is banned will be unavailable to honest citizens but will be easily obtainable by people who have no respect for the law.
