I've handled a gun from a fairly young age, taught by my grandfather, a ww2 vet. Over the years I've shot skeet, some shooting competitions for fun, etc.
The most dangerous people I've ever seen at any of those places/events were the kind of people who loved buying lots and lots of guns, especially the 2A nuts who claim its all about protecting from the tyranny of the federal government. IMO, they just wanted to feel powerful - and as a result, they were negligent and dangerous. I know one of them who shot themselves in the leg pretty recently, because they ignored the most basic rule - treat every gun as if its always loaded. Guess what? That one was! And now he has a hole in his leg.
Sorry for getting into a rant there.
Guns are horrifically dangerous and should always be treated as such.
