He might not do anything that warrants him having anything recorded against his permanent record if he appears as Leo? Just because Mudd shows up in an episode it doesn’t mean that he has to be charged for a crime... he could get away with it, or just get a ‘friendly’. Also, perhaps in Mudd’s Women the Enterprise was chasing Mudd’s ship because it flagged up in their database as a result of something he had done under the name of Leo in the past. Maybe Leo was known to ignore starship communications signals and was also known as a menace to navigation… it would make sense.Starfleet and the Federation must wipe their database of criminal offenders once a year, too. Nah.
Mudd would have to be dumb or sloppy to use the same alias after getting caught, and he's neither.
