I caught something this time that I didn't notice the first time around. Just before Moose started the message portion of his briefing, he paused and actually had an almost pained look on his face. It appeared to me that Moose did not want to release the sniper's "duck" statement. His facial expression conveyed almost severe angst. Could it be that Moose is also concerned about coded messages?
I noticed that, too.
Seemed like he was forced. Not sure he made the right decision. We know the shooter kills at a whim, however IF this indeed was a code for other cells to go into action, then we;ll have multiples of killings..... going on simultaneously. *sigh*
