Sounds to me like someone is very afraid of being incarcerated the rest of his life. It's just more of WRE's typical hypocritical, lying, manipulative blah, blah, blah. He can't manipulate the police, he can't manipulate his family, his ex, not even LLB (innocent or not, but if she knows something about him, he doesn't want her to talk). Who is left? The public.
Methinks he's managed to tighten the guilty noose a bit tighter...he's now implied that LE knows that CB, LLB, and their "driver" know something about him and Lonzie's disappearance and therefore are trying to keep them in jail until they spill the beans on him.
I also wondered if this is an attempt to get a message to or manipulate them (if they do know what happened to Lonzie). I got the impression his defending their current incarceration was a way of sending them the message that he is "loyal" to them, perhaps hoping they will remain loyal in return?
GutInstinct, I have two schools of thought because I keep getting mixed messages from WRE's mouth...
One, he's the sole actor in Lonzie's death/disappearance.
Two, they were all guilty in Lonzie's death/disappearance and made a pact to cover it up.
I lean towards one, because I do think someone would have turned by now to save their own skins.
ETA: in scenario two, I mean at least one more person knows what happened but perhaps three or even four. Because he sort of implicates that the other guy who was driving knows something too. Unless, I'm reading it wrong.
