Did you ever hear what Moose was so upset about? I'm sure he's trying very hard and all LEO feel guilty when they can't find perps - and it's all so public. I did hear him say that he feels diminished because he can't find the guy(s).
No, I didn't, BUT I think its over certain evidence leaking out. Right off the bat this morning it was reported that the casing was found. During the conference when asked he declined to answer. A few moments later during a top of the hour update, they mentioned the casing again. Next conference I think he admits to the evidence.
I'm guessing it has to deal with certain info that wasn't meant to go public. And then of course Carl Cameron blabs on tv about taunting the sniper to make a move.... come on Carl, I thought you were smarter than that!
