What you say is true, but it does not strike at the heart of the issue. The danger of the gun is not the gun itself; it is the person holding it. The person holding the gun kills someone, not the gun itself.
Thus, to argue (as the gun control extremists do) that we should ban guns in order to make the world safer is a false solution. The world is not safer (the criminals still have guns) and the situation has been made significantly more dangerous by the fact that no law-abiding citizens are still carrying.
The solution is not to get rid of the guns, or the ropes, or the chemicals, or the needles, or the knives, razors, strings, electrical outlets, water, fire, or mechanical instruments of any kind. The solution is to cultivate a society that is based on commonsense, basic principles of self-defense and careful handling of dangerous things.
