Question about this week's episode of Law and Order: CI?

Does anybody know why they were advertising this episode on USA for a whole week as a "special extended episode", "...one hour won't be enough" and it was a normal 1 hour episode, and next week's episode doesn't seem to have anything to do with this one? WTF?

I know, I hate that alternating thing too. I mean really, you put Chris Noth in there and its just regular Law and Order. It's the crazy guy who knows everything that makes the show special.

Not even "The Professionals" seem to know. This was from TV Guide... "Overall excellent episode, my only complaint was 鈥?was it not suppose to be an extended episode? My clock showed it over before the hour was up, then just three minutes of commercials before the preview to extend it. What was that?"

I know its crazy. I hate the way the alternate between Chris Noth and partner And Vincent Denofrio and partner. Sorry I love The orginal CI cast . Esp. Denofrio (yum) He is hot even when he is crazy

Haha Im glad Im not the only one who thought that it was a little short. I didnt get to watch it when it aired at its usual time but I watched it when they showed it again later that night and I couldnt help but look at my clock completely dumbstruck because I thought it was supposed to be longer than its usual hour too. I thought maybe because I didnt watch it when it originally aired maybe I got jipped some how but I guess not.
