I'm also suspicious of people handling guns. I found that, as a rule, veteran shooters are pretty safe. It's the beginners that scare me. They're dangerous because of a mix of fear, incompetence, and ignorance of the rules, or etiquette, if you will. On more than one occasion I've had my rifle or shotgun plucked out of a rack by a new shooter, and admonished the person that you never, ever handle someone else's firearm without permission. I've also seen riflemen point their muzzles at the horizon and jack a round into the chamber. Or, when picking up any firearm, not check the chamber, which you always do, never mind whose gun it is.
