Ms. Parker is wrong. Alive, he's a danger to other inmates, guards, and anyone who gets in his way if he tries to escape - he knows he'll be spending the rest of his life in prison, and has no reason not to kill. Dead, he's only a danger to worms who get sick eating his foul carcass.*
[*No worms were harmed in the making of this rant.]
And I bet with him knowing he is a lifer and not needing to continue to with the good behavior sham, the contracts will be out.
