, did you see tonight's L&O? That's a great example of *today's* Jack going off on a tangent. He charged a group of street brawlers with *terrorism* knowing it would get them a life sentence if convicted. Cutter had to talk him down.
As for the episode you mentioned, with one of Jack's old girlfriends withholding evidence because she thought that's what Jack wanted - she deserved her fate. She fucked up the criminal justice system. If anything, Jack went easy on her.
