Jeez tons of PD's, big and small, have surplus military FA's in their arsenals. Our department did not but most of the surrounding PD's did. They aren't issued for patrol officers unless they are trained and qualified with them as members of SWAT, TAC or similar teams. Would be fun if you could just check one out and blaze away but it doesn't work that way.
These rifles and more are also located in some places you'd never image. I can't say where but they are government related and if you knew you'd understand why if you thought about it. Anywho, I have no problem with it because should the federal government ever turn on the citizens it's good to know there are select fire weapons in the hands of our local state LEO's because they are more likely to fight on the citizens side. Plus, in the event of some crazy situation like the Hollywood shootout I'd prefer the good guys are equally armed.
I hope you are right. I think alot of LEO will tuck their tail and do as they are told. But, I am one of those guys that think alot of people will hand over their guns when told to. I have nothing agaist LEO having these guns, I just think that I am one of the good guys too.
