From The Objective Standard:

Granted, some people misuse guns: In 2011 an estimated 11,101 of 15,953 homicides involved a gun, as did 19,766 of 38,285 suicides, as did 851 of 122,777 accidental deaths. But such misuse is not grounds for outlawing guns. Legitimate laws—those that protect individual rights—do not punish law-abiding individuals for the crimes of others, nor do they restrain the psychologically healthy because of the suicidal, nor do they restrain the responsible because of the irresponsible.
