Maybe it's time to rethink how this country does policing. And sometimes that takes a changing of the guard.
Not even an ACAB type. I've had several run ins with the police, some positive, some negative. Some of them were extremely friendly and helpful. Others were power hungry and lied through their teeth in court. The profession as we've made it can unfortunately attract people for different reasons, both white knights and bullies.
Mass resignations are a natural and probably necessary step towards actual reform.
If only we could get congresspeople and Supremes to resign en masse too. This country is long overdue for massive social upheaval.
Setting aside as presumably unproductive the discussion of whether Democrats are actually demonizing the police, I think it's fair to say that especially Trump-era Republicans did and do their share of demonizing.
