When I was much younger, all the talk was about Uzi's. I seem to remember people losing it, and using them to wreak havoc, or commit crimes. Of course they were full auto's. I don't remember them being legal at any point, or were they back in the past before certain laws were enacted? Anyway, the media was all over them much like they are now over "assault" weapons. Where did they go? Did they all go under ground? We're they somehow collected and destroyed? It might be interesting to trace back what happened then, and maybe learn something.
