There are too many police officers who earn a weekly paycheck. These are needed to contend with the hoards of habitual criminals whose only function is to rob, rape, maim and kill.
Nearly all of these criminals have records showing their hatred for their betters. An efficient system would round them up and destroy them all. That would severely cut down the need for police officers to patrol, manage traffic, answer emergency calls and protect and serve as police officers are supposed to do.
