There are good cops and bad cops. Unfortunately the guns are a big force multiplier and it really amplifies the bad.
I agree about the training. I think it goes hand-in-hand with the general militarization of our culture as a whole - which starts in school, where kids are raised to follow orders, take standardized tests, and not ask questions.
What can we now call this? Or can we trace the this into a basic level Where children are being exposed to various things at their early years.
