By jingo, I believe I've spotted a trend.
In the Chessani hearing, Sgt Dela Cruz testified against Sgt Wuterich.
In the Stone hearing, Sgt. Justin Laughner testified against Lt Grayson.
Now, in the Sharratt hearing, Former-Marine Graviss is testifying against Sgt Wuterich (or whoever "he" is).
So the prosecution uses a little time in each hearing to give their "star" witnesses a warm-up. That's not going to help with Graviss. He just sounds like a dope.
You are right about the trends. The prosecutors try to get sound bites out about all the other Marines where there won’t be a defense expert to counteract these statements. In the writeup, the “He” sounds like it was referring to Dela Cruz. That’s why I was asking about who asked for this info from Graviss. I couldn’t understand why the prosecution would try to make Dela Cruz look bad.
