As I see it it wasn't that he wanted the job - it may have been constructed specifically for him for all I know. His mentor has track record for employing him across his area of expertise.
I can't see that he could have been any kind o of fit. And that is why public scrutiny is vital - which we seem to agree on.
But the bottom line is that he has been complicit in, benefitted from a stupidity. That he now wants to sue those who committed that stupidity, including his mentor/mate perhaps, it just seems like more of the same self absorbed, lack of reflection, I want, I want isms we see so much of!
