In the United States, at least 250,000 die annually from medical malpractice. So should we tell people to fear doctors? Doctors have immense power over us once we are the room with them. They must be evil.

Yeah but when doctors screw up, they can be sued or arrested. It is extremely difficult to sue police in this country for their equivalent of medical malpractice. And getting them arrested and charged, while not nearly as difficult as BLM claims, is still much more difficult than it should be.

but can we stop lumping in every officer into the same group?

We are not lumping every officer into the same group, but we are saying that good officers work for a system that's so screwed up that their good contributions, while important, are ultimately meaningless if they're also part of the machine. It's like donating half your $50,000 salary to charity when your job, that's very noble and it's of great personal cost to you. But if your job is to collect millions of dollars in taxes for the king, some of which are just but some of which are not, then who gives a shit about the 25000 of charity?
