There are many problems to fix.
You are not kidding here. San Bernardino California is going bankrupt paying the pensions of LAPD officers who moved there specifically to retire. Not to mention all the tiny PDs that are stealing from innocent people using asset forfeiture. The racial profiling by small town PDs that will essentially run non-whites out of town on a rail.
Everyone has a story, like my brother who got pulled over for a "Suspicious right turn" when he drove through the wrong town with my black friend. Or my other brother who got a ticket for riding his motorcycle on the sidewalk without a helmet while running a left turn light... on his bicycle. He got more community service (110 hours) from the corrupt state commissioner than another guy who beat up an old lady.
Police quality is a huge issue in the US. Justice is a huge issue in the US. We have a LOT of work to do.
