I know accidents can happen and you do not have to be stupid to be involved. What I was saying is, that is the specific cases listed above, either better training or a smarter owner could have stopped the accident. Stupid people can make for some very stupid accidents.
There is no excuse but stupidity for letting a kid find your gun and shoot a sibling. Same for killing someone when you unload a gun, that was both amazingly stupid, and bad training. I was taught you never point a gun at anyone at any time unless you plan to kill them. That includes when you unloading your gun or when it is unloaded.
As for Leslie, his is a true accident, it would have been nice if his gun where safe to drop, most are, but most .25s are cheap **** and he got unlucky, and then lucky again when it did not hurt him or someone else badly. That is far different then some tool unloading a rifle and killing someone. I can not even imagine how that could have happened.
You are far more likely to be killed on your scooter, by some driver not watching what he is doing then I am to be killed by a firearm in an accident. (well maybe, if you where in the US I would say for sure) Hell I am far more likely to be killed in an auto accident by some stupid kid in a Honda.
That said I do not think it is a bad idea to make sure the person buying a gun knows what the hell he is doing before he takes possession of it.
Hell, the many times I have taken non shooters shooting, I make them listen to me, and learn all the safety features of the guns they will be shooting, basic gun safety and then for the most part I do not shoot, because I am watching everyone of them like a hawk.
