That seriously surprises me. I was almost sure there was a legal obligation at least in the case of felonies. I suppose that's what happens when someone gets their knowledge of the law from watching TV.
Both Crump and Jackson are officers of the court. I thought they were obligated to inform LE of any possible felony. If, and that is a HUGE IF, they discovered something that TM told Dee Dee that could be construed as helping the Defense then if they coached her enough to work around it, I would find that morally reprehensible. But would it be unethical as a legal standard?
IMO, she caught Bernie de la Rionda off guard a couple of times and he didn't question her further in places where I thought he would naturally would. If he were really seeking the truth about what happened that night, instead of trying to stick a charge to GZ, that is...
The whole thing smells of politics, IMO.
