Beg to differ with you Tom, but stolen AK clones are indeed being used in banger shootings and a good friend of mine got his squad car shot full of holes by a bank robber
with an AR15. There are several cases where dead-enders have used AK's against officers on car stops, too.
Do I advocate regulating them? Not on your life. But those guns in the hands of criminals are definitely a part of the landscape, for us.
