I have to suspect the same thing. My brother-in-law is a cop---and he talks about corruption all the time---who is on the take and who is not. Are there dishonest police officers? Sure. Lawyers? Yup. Judges and DA? YOU BETCHA!
Cops--especially those with kids of their own---eat trash perverts like Ritter for breakfast---but they walk because of dishonest prosecuters, judges, and lawyers. A few years ago in Upstate NY--a prominent State Senator was caught trying to take the Spider Man underwear off little boy in a motel room---and he got a "warning." What the hell is that?!
