Re: So good they named it twice.
They charged him with one count (at least) of access fraud (doing it himself) and one (at least) of conspiracy to commit (working with/facilitating others to do it).
With the "conspiracy to commit" conviction in hand, should they manage to catch anyone else in the group, the Feds can lean on him to rat on his co-conspirator, with the carrot of reducing his sentence. That might not have been possible without establishing that he, in fact, HAD conspired with the prospective "X".
