As it is above, it is below...
I think these occurrences are just manifestations of what is going on at higher levels... These insane "LEO" on "Citizen" interactions are just a trickle-down of the current State vs the People paradigm. The velvet glove is getting threadbare.
You make a good point and remind me of one. When I go into any business and the minimum-wage-or-near-so clerk is rude or service is bad, I am never rude or upset with the clerk. I am a firm believer in the theorem that all problems are management problems. I have found across many years of leading people that, almost without exception, people meet the expectations set of them. When employees are rude that's because their management probably behaves the same way and they are replicating that behavior. At best it is because they know their management either does not care or does not implement mechanisms by which they can identify bad behavior.
I don't think the police are so different in that regard. They are doing what they believe their bosses expect them to do - or at least know their bosses will allow them to do. The effects of bad policing are so much more serious than bad service at McDonald's that the police definitely need to be held to a higher standard and, like any one, when their actions turn violence they need to be held personally accountable. Even so, in the end, they are doing what their bosses allow or expect them to do. This is not just a street cop problem. It's a management problem. Whoever failed to set the right standards and expectation in these officers need to go. The cops need to be prosecuted for causing a death while committing a felony and put to death. Unfortunately, Illinois outlawed the death penalty in 2011 so we should only settle for life without parole. Their managers, chief, and city leaders need to be charged as accomplices.
I took taser/nightstick/pepperspay training.
I was told by my professional instructors that the proper term was "less then lethal" not "non lethal"because it can be lethal.
Then it ain't less-than-lethal either. Dead is dead, not less than dead.
