Why are you not applying the same logic to the police state? The police murdered George Floyd, so doesn't that imply the police are no longer innocent at this point? Why is only one side beholden to rights and responsibilities? At that point isn't it your obligation to stand up to a group becoming criminal?
That's the equivalent of blaming any European for the Holocaust or any Muslim for terrorist attacks or any eastern European for car thefts or any other stereotype you can think of. I mean isn't this what the whole thing is about? Abolishing stereotypes? I'm all up for that, but trying to abolish something by actively using it seems really counter-productive to say the least.
As I previously said, I've had encounters with horrid police officers, regardless of my polite manners. But I'm also aware policemen are people with the exact same problem like any of us. I see something deeply hypocritical in the whole situation(and the many similar situations across the world over the years). Truth be told I only know one police officer personally. And the truth is he is one of the kindest people I have ever met, despite being utterly strict in his work. Now given the opportunity to choose between rocks flying his way and people calling him a dirty pig or playing with his 2 year old granddaughter in the evenings, which one do you think he'd rather pick?
