Unfortunately it's a small minority who are ruining it for the overwhelming majority of cops who do a good job day after day.
I guess I could see your point if I had a personal standpoint from which to agree. I have only informed reporting, from both reliable and not. The preponderance here lately is not sympathetic to your thought I think.
My personal experience with LE is mixed. Some good (principally in my own small little town with officers who largely carry Model 10-like revolvers and the insane Rambos who infested the county in which I used to live)...
By and large I am not going to depend on them or anyone else to treat me as a citizen vs a subject I think. We have far, far too many psychos in LE.
