That is a shame, but it shows an inherent problem with policing and dealing with such situations. Human beings are too prone to not living up to the ideals that the badges and uniforms that we bestow upon them were intended to follow. Or maybe America just doesn't actually realize that those ideals are a sham and always were. Its actually so rare when they are realized that we go out of our way to signify them and bestow medals upon them for it.
Sorry, no. There's ample evidence of such. One even took it to the Supreme Court to make sure that it was legally acknowledged.

I had a longtime friend become a cop. He straight up told me that their first priority was
always Cover Your Ass (they say CYA because they know that it makes them sound like assholes so they abbreviate it). Certainly there are plenty of officers that are willing to eschew that, but saying its completely without merit is objectively false. The issue is that its become systemic in too many departments, where they openly view the public as their enemy and so they're just their to protect their own against the whole rest of the world.
