My parents asked me this question years ago when some new stats came out on accidental shootings. They were surprised to learn that I had done my student teaching with the uncle of a kid who accidentally shot his friend with a shotgun. The uncle had helped with the clean up and was kind of an emotional mess that week.
I then reminded them that they too knew somebody who'd been accidentally shot. A friend of my brother who'd been at our house many times shot himself in the neck with his own air gun. Even though it only shoots BBs, it was a really bad wound; he was touch and go for awhile there.
FTR, I'm a big believer in 2nd Amendment rights and responsible gun ownership. I think armed citizens are perhaps the most reliable crime deterrant. But accidents happen. And stupidity happens.
