I never understood this mentality. My uncle was a cop in a good sized town in MA for 40 years. He talked about his job a lot, and he always had interesting stories, so me and my cousins asked a lot of questions. He NEVER thought his job was dangerous. He was just like meh, it's a job.  I mostly pull people over for traffic stops. He was loyal to his friends but not in like a fuck everyone else, scorched earth kind of way. He hated shitty cops and hates stories of all the cops who do these horrific things. He always would get so mad at these videos and be like, dude it is NOT that hard to restrain someone quickly without escalating the situation. I mean I guess my uncle was a unicorn.

Not all cops get the training I describe. Some, most probably, approach their jobs in a perfectly reasonable manner. But enough clearly don't that it's a huge issue.
