The way I look at it, regarding DR's competency (and other lawyers involved in this case is this:
Fast forward 1 year, all 7 co-conspirators, will be jailed, with 6/7 of them serving LWOP. That's pretty unusual. Most instances the majority of co-conspirators will look to make a deal, in this case probably only one ended up making a deal. How much is this attributable to the lawyers?
DA and CA idolise DR, he can do no wrong in their eyes. He is their lawyer and he has been paid handsomely for his services, so it seems reasonable to assume they would listen to him. Some have argued that if he wasn't sycophantic and overly positive about their chances, they would simply find another lawyer, but that isn't the case as they know him, respect him and pretty much have him up on a pedestal.
So the question is, did he tell CA how strong the case was against him? Has he told DA? The case against DA is a slam dunk, she's going to be convicted and she's going to die in prison. This is what DA should be telling DA, but I don't think he is, simply because they have not attempted to broker a deal with the state. Even if the State rejects it, it's worth a shot. 10 years and she admits culpability, but doesn't throw WA or HA under the bus. Gets out in her mid 80s and lives another 10 years? The worst the State can do is say no.
Same with Kawass and KM. Perhaps if there had been a different lawyer, KM would be relaxing on a Miami beach playing with her kids. And same with WA. Is her lawyer really expressing to her how strong and voluminous the inculpatory evidence is? WA can maintain her innocence to her lawyer, but his duty is to do the best for his client. If he's not telling her she's in deep trouble, he's not doing his primary duty as her lawyer.
