I think it's just out of pure jealousy. CM was planning on writing his own "tell all" book about the case which he planned to have out by the end of this year....

that didn't work out for him and the huge success that JA has had with his book on the NY Best Seller list and with multiple printings is probably really getting to him. That and they have been hoping on raking in cash from selling an interview with KC... which also appears to be going no where.
Ahhhh the smell of sour grapes is in the air. LOL I feel sort of sorry for CM (NOT!)
