You can acknowledge the very real issue of police brutality and systemic injustice without buying into the acab bullshit. There are 700,000 cops in the USA, I'm sure each and every one of them are murderous pieces of shit who are either racist or just bloodthirsty. That's very plausible. /s
With that being said, I don't buy into the " just a few bad apples " rhetoric either. There are far too many shitty people that are cops, and steps must be taken to ensure that people like Chauvin are not allowed into the police force under any circumstances; and that cops are always held accountable for bad behavior of any sort.
