I think Geoffrey Jackson will make a good showing. Here's why: He'll have gone through the testimony and will be well acquainted with the Angus Stewart's line of questioning.
I think Marvin Shilmer comments were accurate:
1. Jackson will defend past policy as an honest--though perhaps flawed--attempt to abide by public policy on mandatory reporting. 2. He will further express appreciation to the Royal Commission for its initiative to move Australia toward a uniform public policy in relation to mandatory reporting, whatever that might require of Watchtower and its appointees. 3. Otherwise he will offer as much cooperation as the Commission requests related to the matter of responding to reports of child molestation.
Jackson's a complete idiot, which by all accounts he does not seem to be.
