No, I think that's a different state of mind. He's moving too slowly, too methodically, too systematically. A person who just lost someone at sea would be madly trying to get help, yelling, running, banging, screaming and begging for help. I think his movements show an amateurish calculation. As in, "OK, I neexd to move around, make noise, act like I'm looking for help," but compromised by a state of mind that is distracted, self-absorbed, lost, afraid for himself.
Mind you, I recognize this is pure guesswork. These are just my observations. They are based on 20 years of practicing law and trying to measure the veracity of witnesses and so forth, but that doesn't make them any less guesswork.
I think they'll nail this ******* before it's over, despite the fact that they (ALE) are totally incompetent, understaffed, underfunded, undertrained and lacking in resources. He's just that stupid.
Edit: Ha. It appears that calling a GG by his true colors is prohibited here. I meant to say he is an azz-hole.
