Based on the style of questions I've observed from Stewart and McClellan, I think some of the more frustrating questions presented to Jackson will be those attempting to get him to agree that specific items of policy have been 1) traumatic for victims, 2) traumatic for the general membership (think: "captive organization"), 3) a danger to children in society at large, and 4) what expected changes the Royal Commission can expect to see the result of its unearthing of Watchtower-induced trauma by policy.
Because the GB is set up as a rule-by-committee one member would really be sticking his neck out to venture views on specific items like this. 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. So he's going to have to offer response to everything put before him. It's going to be a show. That's for sure. Can't wait.
