Regarding Marvin's comment:
It's not safe ground and by past accounts GB members who've ventured specific views that were yet to be adopted by the GB found themselves in hot water. But Jackson is going to be front and center, and the GB must know the video is going to go viral among the JW and ex-JW community no matter what he says.
It may also be a an Ace held in his hand.... If he is asked questions that cause his answers to "go against the grain" he WILL be on video, there will 'relatively' be no way to spin what he said (it will be on the internet, haha) (and yes, there is always a spin, but for the person who wants the bottom line, it will be there in black and white).
In the past, when others went to court, the transcripts may have been harder, more expensive to find...
Nowadays, in this information age, people are aware of how to look court cases up, get transcripts, search the net, etc.
