I used to respect them, don't anymore. Co-worker who is deaf has been assaulted twice by police officers. Another co-worker is a retired cop. He can't stand his former police department. Half of them he said are veterans who shouldn't be involved at all with the police and he believes that's the underlining issue. Not sure if that's really the case but when you have a retired cop saying things like that I take notice
There's been plenty of ex-cops and even current ones that have said the phrase "the police should be trained on the west coast and the military in the east, because that's how far away they should be from each other".
Part of the problem is the police became military units, not public service units. I appreciate what soldiers do for us but military style organization and tactics should stay over in the military. Shit, some police departments have better materiel caches than the fucking local national guard outpost.
Of course, that's just one component. There's other huge issues, like how a lot of police departments either are heavily KKK/etc infiltrated or how some departments have been kept in white supremacist hands since the end of the Civil War, sometimes just via the Chief job being handed down through a family.
