I'd guess every govt. agency has some bad employees that need to be educated/incarcerated.
That said, I have volunteered for years with law enforcement. This weekend, in Cheyenne, I'll be teaching with local law enforcement. Teaching NRA firearms classes to 12 through 70 year olds. Our compensation is more knowledgeable, skillful and safer citizens exercising their 2nd Amendment rights.
Also, my cousin is a cop near Oklahoma City and has won awards for bravery and community service.
