Don't underestimate the power of SPIN, if anything has to change as a result of this enquiry, they'll spin it to the max. (Aren't we loving, making our org more safe for the little kiddies)
Don't forget, a large percentage of witnesses won't even have heard of the ARC, so any noo lite on procedure will be taken at face value, as a loving alteration, more evidence of us being god's bOrganisation.
As for previous victims who will no doubt be outraged, they're a minority who can easily be dismissed as damaged or bitter.
Don't get me wrong, any change that complies with the 'world's' advanced protective policies of safeguarding the vulnerable is great news to me. But this is an organisation that has twisted and turned, using spin to weasel out of multiple end of the world predictions. A slight change in policy will be nothing to them.
