Most police officers are good people. The protesters are being brainwashed into thinking there is a problem with police brutality. The truth is things have been getting better every year in regards to this. It's certainly not worth it to have your city burned down. These "protesters" will regret this disaster they have created.
Ever lived in the slummy part of a city or town? Anecdotally, I grew up in South-central Minneapolis about 2 blocks from where this went down, and understand (but not not necessarily approve) what the violence is all about; its a 'walking in the shoes' thing for some. When the police see you as dirt, and treat you the same by roughing you up, shaking you down, kicking in your door and dragging you and your family out of your house under a mere 'suspicion' or proximity, you lose respect - for police, government, business, and any person different from you not in you circle of friends or local gang.
When a straw like Floyd happens to break the community-camel's back, it feels like the point is reached where NOBODY is on you side, and you lash out by treating everyone and everything like you have been treated your whole life - kick down doors (any doors), and rob and pillage those within reach and treat any available target in the way you have been treated.
Kumbaya moments, no matter how many locals congregate and peacefully protest, accomplishes virtually nothing beyond a news-clip on page 10, and it takes torching visible public outlets and police stations to get someone to even notice what's happening. When you're seen as an incorrigible criminal with no redeeming financial, social or moral value by default, true or not, there is little to be lost treating others the same way.
"So how how does it feel to have Your life taken away just because you are black/minority, poor, and perpetually struggling to survive?" When the gen-pop at large walk a few miles in their shoes (be it having their car smashed, their store looted, or police station burned), they just may understand a little better, since nothing else works.
P.S. Even though white, I grew up much the same as a poor black child getting my a$$ beat, my toys stolen, my friends bullied, and looked down upon by one and all because of my neighborhood and my parent's income and lifestyle. It is impossible to understand without walking in those shoes...
