It's not hard to gather that you get what you pay for "talent" wise.
Between that, and bullshit politics, this is why you get the people you do with the power to remove someone's freedom. It's the reason I left my career choice of law enforcement and went back to school to become a Physical Therapist. It was a thankless job, which I was fine with as the feeling of helping is great, but the low pay, poor health benefits, and nearly locked in place advancement, not to mention risk on the job forced my hand to leave that career and get something that can help me be a safer provider for me and my fiance, and our future family. It is what it is I guess...
This doesn't excuse highly paid officers who still commit crimes. I don't think it's about the money, I think it's about psychological changes to an officer once exposed to the toxic environment over time.
The police face a similar corruption situation to politicians. The environment becomes toxic over time for one person, and so they become part of the insanity that they originally arrived to change.
In other words, throwing money at the matter would do little. A system change is necessary. There should be limits to how many years a politician can be active, and there should be a limit to how many years a police officer can be active.
I have little doubt the life of a police officer is tough, and that the actions some officers have taken that resulted in prison life do not reflect the mindset they had when they first entered the academy. I'm sure our soldiers overseas experience that same warping, and may not be able to come home the same.
This isn't just an American situation. You can see it across the world.
Governments attempt to balance out police power with stronger justice systems to hold them accountable for the inevitable divorce from justice. What we have in the US is a skewed power system that consumes minorities.
I don't sense that to be efficient. Limiting terms/years of service would probably be more efficient.
I've been looking for a study that correlates years of service to police abuse, by the by.
