For the most part, US police don't do what TV shows and the news tell you they do.
They don't run in schools to save children from gunmen.
They don't recover stolen goods.
They don't protect you from domestic violence before it happens.
They don't solve sexual assault cases.
What they do with all those billions of dollars is beat up poor Black folk and extract money from them through fines, tickets, court fees, unpaid prison labor, and theft.
That's the job. And it doesn't keep you safer.
