For what, did he fly drunk, violate airspace, act as PIC without getting recurrent training?

I think you've totally fallen for the "FAA dark magic" perception. There is no ATP renewal and I don't think anyone in the FAA cares what someone does that doesn't involve flying. I know of people that are in jail that still hold FAA certificates...because there's no basis for revoking them.

While depending on the conviction, this could be grounds to deny an ATP, the guy already has an ATP, so that's nothing that the FAA would be concerned about. Outside of medical, I can't think of anyone that would care.
