A high school friend of mine made the mistake of doing that because in the past he had cooperated with the arresting officer (i.e. snitched). However, what he didn't realize is that may have no bearing on what the officer might do but even more importantly, it's the prosecutor who decides if he's going to pursue the case and they did not care about his past history with that particular officer. The police are not your friends but more importantly they aren't the ones who do the prosecution. They interrogate and they have a job to do.
