I don't see how this story is dragging Al into it. He just happens to have been the client John K was working for when some of these allegations happened. They asked Al about it and he said he had no idea. That's the beginning and end of his connection to the story. What makes anyone think that Al is being dragged into it? It doesn't reflect on him at all.
It is very sad that someone I've thought of as a titan of animation for my entire life has been revealed to be a pedophile, but that's part of the reckoning that has been happening over the last six months or so. A lot of people are finally getting their due.
