The terminology of crime.
Does anyone else feel insecure when speaking about the status of a citizen caught up on the criminal justice system? Appellate cases often refer to the prisoner as "defendant." But since this person has been convicted, is he not now a "convict"? And what do we call a citizen/suspect who has been indicted. Is this person an "indictee" or "criminal defendant"? Do we further distinguish by saying pre-trial defendant vs. in-the-arena defendant? Or does one size fit all?

First step, citizen. Then suspect. Then criminal defendant. Then convict or prisoner. Am I correct here?
If the defendant prevails at trial, is he now the "acquitted" or does he remain the "accused"? I prefer citizen but I note much inconsistency in usage (my own included).
