There is a common perception in America that criminals are morally bad people who must be punished, instead of a perception that they're desperate or broken people who need assistance or reform of behavior. There is a private prison sector that is literally allowed to use prisoners for manual slave labor. We have one of the largest prison populations in the world even when adjusted for our large population.

There are a ton of factors that play into why there is a mistrust of the police (on both side of the political spectrum) but there is also a common air of ambivalence about how we treat people once they're marked criminals. You see it every time a large media stir comes up because of a high profile police shooting. "Well, he was no angel. That thug had a criminal record, so the cop probably..." as if it's impossible that the victim could have been a criminal AND the cop used unneeded lethal force.

Your point is a little blunt and lacks nuance, but it's sentiment seems in line with what many prison reform advocates perceive as being the prevailing culture in the US towards criminals and prisoners.
