I really don't think even -that- CNC machine is that easy to set up.
I had a slingshot when I was a kid. It was quite capable of killing a squirrel, outright. Funny how, after I had that, the 1 or 2 bullies in the area didn't bother me any more. But I seldon shot at anything alive, and never at people. I never heard of anyone else shooting at people, either.
Kids did get hurt on bicycles, though. Did you know there was a movement to ban all bicycles? If you have a bicycle, can you imagine it being illegal, even for adults? Do you want to live in that kind of world?
Could it be, that the kids who never had slingshots or cap guns or bow and arrow, are the ones who wave around guns like toys, if they get hold of one?
