The problem for people like that is that they're working in a system that rewards and mandates bad behavior. You want your traffic tickets to stick so you can make quota? Ticket more black and poor people. They won't contest the tickets as much. Drug arrest and conviction quota? Find people who can't afford an attorney, they'll get an overworked PD and likely take a fast plea bargain.

Good people are responsive to the incentives we've created for them also.
