They don't let that one pass, generally speaking...
You will obey my authoooority. I guess the guy should have the e cops for trespassing because they certainly where not there to serve and protect.
Many years ago in Minneapolis, my mom witnessed a cop beating an old homeless wino. She begged him to stop and he told her to shut the hell up or she would get the same. She never felt the same about the police after that, even though she realized not all cops were like that. Still, such an episode errodes trust.
I wonder what she would think of her great grandson who is a deputy? I think she would be proud anyway.
