LOTS of criminals are unarmed. Those who steal the most are rarely armed. Bernie madoff may or may not have owned a pistol, but he did not use it in his theft of billions of dollars.
As I have said, there are far too many guns in this country, and all we can do is realize that we, as Americans,are far more likely to be shot than other people from more rational societies.
When anyone buys a gun, that increases the number of guns that can be used in a crime. It is pretty clear that regardless of sirs devotion to his arsenal, when he kicks the bucket, he will not be taking even one firearm with him. We could say that God does not allow guns in Heaven and the Devil does not allow them in Hell, either. But then, everyone is already dead and cannot be killed in either place. The guns that each person puts into circulation will stay in circulation until they are destroyed, lost or confiscated.
