We are they're employers. That's what the term 'public servant' actually describes; a person who works for the public. Our taxes pay their salaries, legal fees, and lawsuit settlements. If they do not agree with civilians paying their salary, they can work as private sector security. As their employees, we can critique any action by a public employee, regardless of previous experience (or lack of) regarding that employees specific job. 4 months (or less) training is not enough to certify any person in the private sector, much less the public, but it's all that is required of Police Officers (except County Sheriff, which is often an elected position and only requires a pulse).
