I say yes. I think the line, "well, if it was so great, then why don't police and military use it in the USA" is kind of a false argument. I honestly believe the reason we don't use it is because of the Cold War stigma attached to it. I think if you equipped the entire US armed forces with Kalashnikov (47, 74, 105, dragunov) rifles, we'd have the same number of kills and relative same accuracy. I think most of our troops accuracy has to do with training and not the rifle. Personally, I'd feel just as safe and confident in their abilities if I was being defended by US troops with AKs as I would with ARs.
As for police. They're not going to take risky shots with rifles due to legal liability, so why are we spending $1000+ to give them Colt Commandos or HK entry guns when we could give them an AK for half price and get the same result? TS if it scares soccer moms. I can't imagine that an AK couldn't do the same job in a domestic room sweep that a $1000+ AR could. Accuracy beyone 200 yards wouldn't matter. And for those that consistantly shoot beyond 200 yards, spend the money you saved on AR-15s and get them a sniper rifle. I mean, for heaven's sake, they do room sweeps with shotguns. That's not a weapon used for pinpoint accuracy, why do the other guys get a bunch of expensive bullet hoses?
