I got my first rifle at 5, but was only allowed to take it out with Dad there to supervise. I was taught to regard it as dangerous, as a responsibility, and how to take care of it. A bit later, Dad gave me a muzzle-loading rifle on the understanding that the amount of work it took to load it and clean in would teach me something about not wasting a shot. I think both ideas worked, though I no longer own a gun.
The cliche that guns don't kill but people do is so simplistic as to obscure any real thought - which is why it's so effective. The fact is, guns make killing easier, faster, even "sexier" (watch some TV). And the notion that "they" want to ban guns or take them away is just as silly: it won't happen in the this country in the foreseeable future. But equally, the NRA-inspired notion that nothing can be done, that we need to be armed, is destructive.
Guns are going to be around for a long time. But we need to make them harder to get, especially in a hurry; we need to make them easier to trace; we need to see that they are properly stored; we need background checks. And we need to make serious gun-handling trained mandatory. it's stupid to register cars and insist that people learn to drive properly and buy insurance, and then to make guns so easy to pbtain.
