Because you posted "but people should really learn to not argue with police or resist them." I disagree at a general level that one should change one's behavior to placate a criminal. If people are having to do that, the problem is not that more people aren't trying to placate criminals, the problem is the criminals.That's true and no one has argued that it's OK to kill black people or to rape women, so why bring that up?
I have known 20-30 police in my life. Most were friends or was someone I was working with constructively. A few times the interactions have been unpleasant. I've never had any need to argue with police. But if that day comes up, I expect them to behave professionally and do their jobs.
