It would be tragic if what we consider as virtuous cops today evolve to be the butchers of the future. The best assurance that our law enforcement agencies do not spiral into the use of excessive force is to secure the integrity of our checks and balances even if this means subjecting themselves to the investigation of the administration’s political opponents. “There is nothing to fear if you did nothing wrong,” the police officers often tell us. This must also apply to them when there are calls for congressional inquiries, probes and investigations.
