Our guys are generally pretty good. They do perform stings to catch coppers doing the wrong thing but to my knowledge, this is only done if they have a reason to believe you are bent.
On the downside, if they get you in their sights and for some reason want to get rid of you, they may not get you for the initial complaint, but they will go back through everything you have ever done and FIND something to get you over. Even if it's only not complying with ALL force directives and policies, no matter how minor. (forget to PBT a driver, can't justify a check you made on a certain person, forgot to sign out a vehicle with the log book and so on) Build up enough little ones and they'll get you.
Again, this is generally done for those guy that are like teflon. Too many complaints about the same thing too close together and either non stick or they are BS, it doesn't matter, and you become a liability to the department.
My boss explained this to me when I had 3 complaints (all BS) in 3 months. He used to be in ESD, so I have no reaosn to believe this isn't true.
I have been complaint free since.
