It's a mixed bag. I've known many cops over the course of my life, both as a "suspect" and as friends. I can't recall one unfair interaction in my personal life.
I also observe that "Cop Mentality" is not fiction, and your take is right on the money. The more power and control you offer or give to a cop, the more his pupils dilate.
Again - I know cops who refer to us as “civilians”.
Enough said.
