No, I wouldn't necessarily be concerned. If I really had a problem with an officer, I would follow whatever procedure the particular department used. I think it would be nice if there was a 'standardized' form to fill out, because I think some people are intimidated and afraid to talk about problems with officers to other policeman. Some people may fear retribution. I personally wouldn't, but I also think my chances of needing to file a complaint against an officer lie somewhere between slim and none.
At one point the 'tester' wants to be able to go straight to Internal Affairs, and I don't know if that is possible or realistic. I think their involvement would be based on the severity of the complaint. If an officer calls you a dumbass during a traffic stop, will IA get involved? Would it go above the Sergeant, or other responsible individual? Maybe some of the resident LEOs can weigh in on IA getting involved.
I think in a way they were trying to set these guys up. It's obvious they have an agenda. It seemed as though they wanted to portray the possibility of retribution. And again, if the alleged infraction isn't going to make it to IA, who's to say the Sergeant isn't going to tip off the officer anyway. You can't register an anonymous complaint, because then there would be no way to properly investigate the claim. Then who do you give the benefit of the doubt to? I would give it to the officer, until such time as so many complaints had been registered against one officer, that a pattern could be seen. You can't inundate IA with nonsense, for that would hinder investigating serious claims. Some of the officers seemed ticked, but I'm not certain it was anything more than just being annoyed at having their time wasted.
