With one or two notable exceptions, I think you have accurately summed up what most of us here fear will be the outcome.
The other two individuals appear to be going to great lengths to, respectively, drag BA into it, and convince us that a case that appears to have already targeted who they think is at fault, will be anything like comprehensive enough.
Interestingly you are still waiting for an answer to your question regarding changing the "blame" for this, if as the trial progresses, it appears there are other fish more deserving to be fried. As yet I see no response to that very valid and important point.
I would hope that the "net" could be cast a little further if justice is really to be done.
