Yeah I agree that he at least spent time in prison, even though he technically didn't serve time for the wiretapping, since the thing that he was accused of doing that sent him to jail, was the fact that he kept lying and contradicting himself about the details to the FBI.
But honestly, returning to the idea that he could direct a future predator movie, I don't think that I would be excited until I see if the final product is good, since he has not directed anything in 20 years, he only directed the first movie and the last time that there was a big deal about the newest movie being worked on by people who worked on the first one, we got The Predator.
