If the threat of guns in the hands of the public - law abiding citizens and criminals alike - is as bad as you think it is - so bad, in fact, that you believe the rights of the law abiding must limited for the better sake of society - why haven't you purchased a gun and taken the training necessary to use it effectively?
I have carried a weapon, in the Navy and in my civilian career. I've seen the damage a projectile does to the human body and the grief of family members when informed their loved one was murdered. I've been a member of death review boards - there are two in every county in CA, one to examine the deaths of minors (17 and under) and the other of adults who had had contact with any county agency.
I suspect many who are so enamored with their guns have a fantasy of being a hero and saving someone with their weapon, killing the bad guy or guys is their daydream. I've seen how trained police officers are affected when in the line of duty they kill a suspect. It isn't pleasant and it seems to never go away.
I saw my father-in-law pale when he saw a Japanses man in a car next to ours and when I asked what was wrong he said, "I killled that man" (he was a gunner in a Billy Mitchell during WWII).
