get your congress to change the law that you can no longer be a cop unless you go through 2 years mandatory full time schooling and spend 1 year in a probationary phase after that working on the beat. if no one detects power tripping tendencies then let them become a full cop. do that 1 thing and it will change policing for ever. after that cops should be continuously re assessed for how they do their job under hard conditions, those that show signs of cracking should be out, no second chances. it takes a very special type of person to do that kind of job well over a longer time, corruption can creep in so easily.
