Do you really know what a policeman is? Do you? it is a private citizen who took a job to uphold the law. A private citizen who is highly trained with weapons (usually).   You know who trained him .. ME !

If you do not have the skills, no you should never go near a firearm or even once think of carrying. And yes I myself stopped a knife attack with a handgun with only pulling it out. And yes I would have used it had I been forced to.

It doesn't make news because it ain't the granny but it happens every day. You know who else carries, lawyers, judges, ex police, FBI, CIA, Justice dept retired people. All Private Citizen. If you never owned a weapon, know nothing about weapons then you do not know what your are saying ..
