Tuc,
I have keenly followed your postings over the years and am struck by the seemingly common thread that runs through each of them. While I am neither senior staff nor politician, may I ask the question you suggested?
Senior staffs and politicians should be asking why these failings were concealed behind a tissue of lies for 20+ years. And ask why those responsible are routinely protected and advanced.
It seems to me that there is plenty of material that Mr Haddon-Cave would have been made aware of - did it fall outside of his narrow Nimrod remit, or was he specifically steered away from it? Your specific mentions of orders to ignore regulations, disciplinary action for following regulations, and acknowledged commercial fraud are surely something you could take to the police on a personal basis? And if the can of worms is already all but open, why has not some maverick MP taken it on as a personal campaign (in the mould of Tom Watson vs News International)?
