Pretty much spot on. However, I have been around one person who was irresponsible and dropped a gun which DID go off and could have struck another person. So I know guns can be dangerous in the hands of irresponsible people.
It's not ONLY that, though. I also am leery of people who might be very knowledgeable about guns and gun safety, and might THINK they are helping stop crime but actually harm a bystander or completely innocent person. I don't think the guy who shot Trayvon Martin thought to himself "Let me shoot a black kid," I think he thought "That kid just broke into someone's house and is getting away."
I am leery of people being overzealous in stopping crime.
Not that I think that EVERYONE who carries a gun would be quick on the draw, but some people would be.
