I think the goal of the RC in this segment is to clearly establish that Terrence O'Brien is a liar. But not only is O'Brien a liar, but freeze-frame the video at 1:49:04 and then tell me that those WT lawyers aren't in on this whole lie. Their reaction is very telling. That look is the look of pure guilt...they've been cornered and caught in their deception. Everyone in that courtroom knows as well as the whole world watching this.
WT is so paranoid of this type of exposure b/c it reveals to everyone that they are fully aware that they are a part of a fake religion. It has been debated often whether the GB knows they are lying or if they really believe their own bs. I submit this as evidence that they do in fact know.
