Lead,
you are correct, no one needs an automatic weapon. I have a real beef with the semi-AK 47s as they can be altered too easily.   They are illegal here also. Well you can get a machine gun permit but it costs a ton of money with some very serious rules and very specific license restrictions and only a few of those licenses are ever given. I only knew one guy that ever had one. Also who the heck could afford the ammo.
