Just how many readers here would want to be a cop today and have every sentence, every move scrutinized like the cops today are? I would not want to be one. I admit I could make a mistake in the heat of the moment and wouldn't want to spend the rest of my days in prison.
No one is perfect. Give cops a break except for those who are chronic abusers of protocol.
If you were a cop, and if you are capable of intelligently performing in accordance with the rules of Procedure and the rules of civilized conduct, the only thing you would need to worry about is the behavior of the ten percent who are ignorant, psychologically unstable, uniformed goons whose egregious misconduct unavoidably casts a negative reflection on all cops.
They, along with the many other cops who instinctively rush to defend the misconduct of any rogue cop because of their misguided sense of loyalty and "brotherhood" are the problem.
