I have never seen or heard of anyone getting hurt at these events, willfully or accidentally. I was a police officer for nine and one half years in municipal law enforcement in Prince George County. I never witnessed anyone in the lawful possession of a handgun wrongfully use that handgun. All of the people I ever arrested or saw arrested for illegal gun possession were also arrested for committing another crime. The gun was not the problem.
Guns are dangerous.
So are automobiles, ladders, bathtubs and the routers and saws in my toolbox. Fools should stay away from machinery. We should not remove property from the members of a free society because the few do not know how to behave. The responsibility for the wrongful use of implements rests squarely with the user. I understand the desire to do something, anything, to reduce violence in any form.
