Katherine Jackson's lawyers think Conrad Murray is a coward who is trashing the man he killed for profit.
One of Katherine's lawyers tells TMZ , "Murray has refused to go under the OATH KNIFE and his attempt to expoloit Michael are despicable and disgusting ." Translation : He took the 5th because he's guilty as sin and now he's selling sordid stories about MJ to line his pockets .
Another sent Murray's attorney a scathing email , calling the doc "reprehensible."
But Murray's lawyer , Valerie Wass, guickly went on the counter attack , saying , "You and members of your clients's family have been bad-mouthing my client for a long time . I don't blame him for talking , especially after ... you tried to protray him as an awful person ."
What's unclear ... how Murray talking about holding MJ's Penis clears up anything .
