In the grand scheme of things there are very few "bad cops". Even the ones you see on the news aren't bad, they just were in a situation that had a bad outcome, not by their own fault but because that's what police do, they deal with situations with a high probability of a bad outcome.
Sure you see bad stuff on the news, but remember that's out of THOUSANDS of interactions people have with police everyday across the country.
What we should be doing is telling people STOP BREAKING THE LAW, and not telling people we need to fix police. Hell if people who broke the law would atleast not resist arrest the amount of bad outcomes would dwindle down to just a few a year.
Don't blame the cops, blame the criminals doing criminal shit that put themselves infront of the cops in the first place.
Jesus Christ folks, when are we going to realize criminals are a bad thing, and if people didn't become criminals they wouldn't get arrested.
