I appreciate the fact that you came with your list of reasons... Here are my thoughts to your bullet points in the same order:
I don’t think that has anything to do with Rashbaum – other than Rashbaum coaching him to be confident.
I guarantee Charlie thought he could pull it off and I don’t think he has the mental makeup to cooperate because he would have had to admit fault and give up his family – he would never admit fault. Same for Donna.
I am not sure where the ‘rumor’ of 1 million started? I would bet my life savings that figure is not anywhere in the ballpark. I agree that strategy didn’t work out and it was a waste of money – but has nothing to do with Rashbaum’s ethics or his or competency as an attorney. Josh Dubin is also associated with the ‘Innocence Project’ – perhaps it was a smart tactical move to get Josh ‘connected’ to the case and Charlie was playing the long game in anticipation he might lose? Sounds like a stretch, but you never know.
I’m sure the potential conflict of interest was clearly explained to Donna by Rashbaum. It was certainly addressed by Judge Everett. IMO, with the defense I anticipate Rasahbaum is going with, there will be no conflict.
As far as his STS interview, I don’t think it was that bad and yes it was an attempt to do a little PR for Donna and probably not the best idea. Again, nothing to do with his ethics or competency as an attorney.
