but, if I get it, you're saying that banning guns won't work well because people with some money and time can just make them anyway? I'm asking, just to make sure I got enough to understand. And if that's correct, why aren't people in other countries making them up and going on shooting sprees?

I don't know that I need to know how to build or assemble a gun to know that most of this is down to mindset. The physical gun itself isn't the problem - it's the lack of education, imo. I very rarely think of guns, but when I do, I get a whole stream of how to handle, treat, clean, fire, walk carrying it, etc, because that's what was demanded of me if I wanted to touch one. And since I can't assume most have a father like I did, I don't feel bad about asking that there be mandatory training, licensing, tracking, limits on who can buy, etc.

I don't do the "guns are evil" thing, but I do know they can kill a heck of a lot better than knives or sticks. If I hear "guns don't kill people blahblah" one more time, I'll scream. Yes, you're right, because that's all we're saying. Of course. ARRRGH! (not aiming this at you, clearly, just being annoyed in general)
