Cops watched cities burn over the summer while being paid.
I know quite a few local police and state sheriffs (I’m not one myself). Some cops are on a power-trip, but most simply want to get through the day, feel they are doing some good in society, get their paycheck and make it home.
If I were a cop, especially knowing a leftist city council and mayor would attack and prosecute cops if any mistake were made - yes, I would not risk my neck to keep ANTIFA from burning a building downtown.
I would also not harass people about petty stuff like wearing a mask. What’s the point?
