Anyone who lives in a high-crime area knows that criminals have access to all the guns they want. Gun control laws simply prevent their intended victims from being able to defend themselves. Incidentally, most uses of guns in self-defense do not even involve pulling the trigger. Once you pull a gun on someone who is threatening to assault you, he is likely to have a very sudden change of plans and head elsewhere. In communities where most people are known to have guns in their homes, burglaries are rare and violent crime rates are low.
Guns deter as well as defend.
A study by John Lott of Yale showed that it is crimes against blacks and women which fall sharpest where law-abiding citizens are allowed to carry concealed weapons. Yet blacks and women usually vote for Democrats, who want to keep them unarmed. Guns are, in a sense, the last line of defense against crime and violence. Moral values stop most people, long before they reach the point where they are about to commit a crime. Yet our public schools have been on a crusade against moral values for decades.
