Hi! Perhaps you don't realize how big a task the ARC has undertaken. They are reviewing not just the JWS, but many organizations or groups. So the JWS are just one small part of the Commission's mission.
Unlike the JWS and their judicial procedures, the ARC has to interview expert witnesses, survivors of the abuse, and the Watchtower representatives. Everything has to be clear and detailed - if it's not, the JWS can use any mistakes or lack of information to wriggle out of their responsibility.
Yes, it takes a long time. And though it would be wonderful if the ARC could lay charges, they can only make recommendations about what needs to be done to protect the children.
I hope that helps with understanding the process a little better. And no, it's not Jehovah helping them - it's just the way things work. xx tal
Edited to say: David Graham - without a doubt, you are correct, sir! Just like other corporate executives, they have a 'Board of Directors' and 'shareholders' to answer to. Whoever, and whatever, they may be.
