Why did Starfleet not believe Harry?
In the episode "Non Sequitur" when Harry ends up back on earth and someone else is in his place on Voyager, he explains the problem to Starfleet who completely refuse to believe him.
Now I understand why no one would believe you if you told that story in this day and age but time travel and problems in the space/time continuum are not exactly unheard of in the 24th Century. So doesn anyone know why they didn't believe him and try to help him, rather then trying to lock him up?
