These are not equivalent. Police who do bad things not only cause extreme harm, but terrorize people whose protection is the whole reason we gave police the monopoly on violence in the first place. This is not a "two sides to a story" situation. This is a situation where one side has all of the power and far, far too much documented abuse of it.
Not only to people in their daily business as police but also in court

They literally have their own term for lying under oath because its so common: testilying

The police kill roughly 1100 people every year.
The entire job of police departments is to interact with people who are breaking the law.
If 0.25% of police arrests turned violent, that means police have roughly 25,000 violent arrest incidents each year. This is a number I am coming up with on my own, but if you actually grew up in a bad neighborhood you will see this as a conservative estimate.
So, if you're looking at this from a raw numbers "how many people die" perspective -- it's actually low.
All that said: cops aren't perfect. I have had bad experiences with them. I think some changes need to be made.
But the idea that there is an epidemic of police killings is not supported by the numbers.
With how often the police lie, it is foolish to give them any benefit of the doubt.
American cops terrified me with their aggressive ineptitude and I'm a polite older white guy with an English accent with short hair and a jacket. They never fucked me up, but I certainly saw them fuck up loads of other people, accept bribes, refuse to investigate blatant drug houses for years, and the like.
It took me quite a while to understand that cops here, while they do make mistakes sometime, are professional people with a sense of humor who aren't interested in displays of power.
Police don't do everything right. But if you think that _everybody_ who had a bad interaction did nothing wrong, well, that's just foolish.
