I really can't blame him for not meeting them. First, if he met a few, then every other victim (and alleged victim; remember there's been more than one case where people have lodged false accusations against their priests) would also be demanding meetings with him, something that would be hard enough for a Pope to schedule in under the best of circumstances, and would be absolute hell for someone in as poor health as John Paul.
Second, we know they're not asking for a meeting to receive spiritual guidance, they're wanting to issue orders and demands to him, which ought to be anaethema to anyone that considers themself a Catholic.
Third, it's a bit cheeky of them to demand an audience with the man at the very top. If I were on an airplane that lost its brakes on landing and skidded off the runway - an event that can seriously injure or kill passengers depending on the airport, speed of the plane at touchdown, etc - I wouldn't expect the CEO of the airline to stop by my house afterwards to say hi.
Did the brakes just have a mechanical failure, or was there a long history of violations of regulations, falsification of safety records, planes sliding off the runway and transfers of crooked mechanics from one airport to another?
Did knowledge of the problems and coverup go up to at least the level of vice-presidents in the company?
I would expect a lot more if there was a long list of problems and passengers were choosing other airlines or driving instead of flying.
