I'd be fine with actual detectives having this for real investigations. But plainclothes units are just that. They still are supposed to do normal police work and don't have the responsibility of undercover investigations. So walking up close to one should be enough for you to recognise that you are a cop. You are not a detective and so you don't need to do those investigations, you are in a branch of patrol. Of which you can use the plain clothes element to stay hidden provided you stay far enough away and be discrete.
