It would be wonderful to have a proper Nuremberg II-type trial where all these twats would be properly interrogated by KCs about all the dodgy shit they have done.
It will never happen, of course. These people have some sort of non-aggression pact between them, where ultimately nothing, not even the most egregious conduct, gets punished by anything worse than retirement on a full pension. We can cite the case of Blair, telling lies to take us into war. Not even a £10 fine and 'Don't do it again, Tony.'
Once you are above a certain level in this country you are completely fireproof.
