Even worse, usually you cannot even submit what you said as evidence, because if YOU ask officer to repeat what you said, the judge can expunge the testimony because it is hearsay (double indirection). Of course, the officer can be asked their side of the story, which will be accepted as an eyewitness (single indirection). So anything you say can (and will) be used against you y the prosecution, but almost never in your own defense. Many people understand at least the basic concept that your words can be used against you, but the fact that those same words cannot help you in most cases is not addressed very often.
