Personally, I am not a big Brett fan. I don't like the way he jerked around the organization, as well as other personal things which are well known.
That notwithstanding, the firm I was with had a business relationship with him. He (and Deanna) were nothing but forthright, straightforward, and honest. I absolutely believe that he did not knowingly do anything wrong.
He is probably not the most detail oriented guy in the world, and listens to his people without questioning them too much. I bet he starts to question them more.
