Several issues:

1. Societal indifference to the plight of people written off as "dropouts", "criminals", "troublemakers", "thugs" and "whores".

2. PTSD and other mental health issues unaddressed in prison and police systems.

3. Sociopathy. There are cabals of sociopathic cops. Often racist and viciously misogynistic. They do so much damage over time that the entire police force is regarded as corrupt and evil.

4. Good cops need a TON of support. They get what's happening. They're scared, and they're alone because they can't experience solidarity with either police as an aggregate or the public. Back them up. Give them the support they need, compare notes, triangulate and overcome the psychopaths. Fast. We're running out of time.
