I wonder if AB thinks maybe he should consider new counsel? Seeing how this has unfolded, IMO one has to wonder. IANAL. MOO
Can't think of a reason to do that. So far, the story about AB leaking the deal to NBC hasn't been verified. AB and his attorneys were still reviewing the proposal when the prosecution pulled it off the table. That wasn't the defense team's fault.
The bigger problem is the prosecution not showing the GJ exculpatory evidence that supported AB's version of the events.
