I'm guessing that you're a shooter (not a big stretch for "precisionshootist"). I know SWAT members and see them at the range, and I'm surprised you don't meet them at the range too. Most are normal, good, decent people. It's only a small fraction who are a menace to society. Even a fraction is too many, but those individuals would still be a menace even if they were regular police. It's problem individuals who are a threat, not the unit they belong to.
The Police should be banned from the possession of ANY military weapons, training or equipment of any kind. The police should dress in blue and only blue. There is no situation that cannot be handled with civilian weapons such as the Ruger Mini 14 and the Mossberg 500 shotgun. The days of cops playing army in our neighborhoods carrying full auto M4 carbines and H&K sub machine guns with suppressors must stop now. Our communities are NOT BATTLEFIELDS !!
