My initial take is that if this is true, Tatupu MUST face some kind of punishment from the team, the league, and the legal system. Without all the details, I'm not going to say "CUT HIM" or "LOCK HIM UP FOR A DECADE," but this IS serious business, and the organization and its fans would be hypocrites to give #51 a blanket free pass here.
How about you hire a driver, Lofa? Cripes. Let's hope he's learned his lesson, takes the consequences like the leader he is supposed to be, and stops this turdish behavior before someone gets hurt or killed.
UPDATE: Lofa's statement
Well said... Now he has to live up to it.
