I was travelling a few years ago, and hanging out in the hotel bar in Portland, Maine, and I listened in on a heated conversation between some guy and a lady whose husband is a cop. They were discussing police brutality and the protests at the time (Baltimore maybe?), and the lady's point was basically "do whatever you want with regulating police behaviour, but I will take my husband coming home at the end of the night over anything else"
It's possible with the falling rates of crime, this may just solve itself (though increasing police training and standards is a good thing regardless).
Step 1: deny jobs and education
Step 2: leverage racist biases among police
Step 3: criminalize drugs
“Look at all this crime! America is so unsafe. We need military equipment and chokeholds so we can go crush skulls.”
