I don't dispute the generic premise, but what would you look for in his case, when he is seemingly the voice of reason, on our side and helping our cause? And to what end? Wouldn't such an effort be self defeating?
If he is guilty of anything, it is not divulging everything he knows as soon as he finds it out.
Why would he do this? The same reason Q doesn't do it, the masses aren't ready for it.
For crying out loud, the man produced a movie of Faith, that was actually well received. If I did find dirt on him, I doubt I could be bribed into divulging it. If there is a need, he will answer later to the Good Lord, the same as anybody else will.
