Man has always found a way to kill man. It has been happening since long before guns were created, and if they were to be abolished it would still happen. I think the real question is, what are you trying to achieve with gun control? What is the problem you are attempting to solve?
I feel that implementing gun control is akin to treating the symptoms of a disease rather than it's cause. You won't cure it. Maybe you will make it more tolerable. Then again, maybe you give the disease time to spread and become malignant. The bottom line is: the disease persists.
~Ninjex~ hit upon the key. Morality. That is the only thing that will make any true difference. If a man wills to kill, then he probably will succeed. With firm moral conviction and discipline, he can will just the opposite if he so chooses.
Here is an interesting resource I think everyone should read. It does not advocate or impede gun control. It is simply a collection of facts. Process it as you will.http://www.justfacts.com/guncontrol.asp
