If you're wondering why Parsons is willing to destroy his credibility in this point, it's because he's desperate to hold the line that Bond Dickinson only advised on the civil side and there's no reason to see them as having operated with respect to the criminal aspects at all.
That's really interesting @nauticant
Would I be right in assuming that Andy realises he's in a bit of trouble?
But his strategy is that it is better for his career, to fall on his sword with the Civil cases, and maybe he'll get a slap on the wrist.
Whereas, if he in anyway concedes to his failures with the criminal cases, this could result in serious, if not, criminal consequences for him?
I.e it's better to accept your failures on the lesser of the two evils?
