I think there could be an aspect of availability heuristic. You don't watch news of police not acting aggressive towards protestors. That doesn't mean it doesn't happen, or doesn't happen even more often than it does. Same with the comment below about why cops aren't speaking up. I've read some articles where they are, but again... it's not going to make news nearly as much as the bad apples do.

This doesn't negate the bad apples and all the bad things that have happened or in any way go against the protests. Just try to be aware when classifying an entire group as bad based hand picked information presented to you.
