There was plenty of time for another of the GB to show up so Jackson could spend with his father. Did they even offer to do that? How about a videolink from New York? Nada. You'd think that would have been just a human thing to do? "Here I am Lord, oh no, don't send me there. How about one of the Pacific Islands with a nice beach instead?" Hypocrites.
Limited sympathy for Jackson, even less with their blatant attempt to mislead the commission on the true role of the GB, and absolutely none reading his written clarifications backtracking from his 'we'll consider it' position he used when under personal scrutiny on the stand.
Likely was just coincidence, especially with him being an Aussie on the GB, although I'm sure the commission would have requested someone from the GB at some point as it'll become very obvious now that JWs won't shift sufficiently on child protection issues. Jackson just didn't get the option not to turn up, whereas they'd have thumbed their nose at the request from Brooklyn if they'd been able to.
