JW wasn't paid - didn't you catch that?
Yes, I caught the word he used and I think that's wrong - but its no indication of intolerance. If you look deep enough you can find something to dislike about anyone.
You seem very sure of his intentions and motivation though.
Being qualified as an expert will allow him to be used again and again as a defense expert witness and THAT is where he will see a financial reward. Do a pro bono, get qualified, and then add that to that extensive resume of his. Gave a little, to get a lot.
