Chilcot - Franks revivivus

As Jonathan Steele rightly points out in today's Guardian, the Chilcot inquiry is a waste of time:

The tally of 140 witnesses seems impressive but almost everyone was a denizen of Westminster, Whitehall or Aldershot taking their mandarin places. This was the voice of Britain's Green Zone, dutiful, narrowly focused and utterly secure.

Just like the Franks inquiry into the Falklands War in 1982-83, and the Official History commissioned by the Cabinet Office fifteen years later. Both utterly predictable from the time their terms of reference were defined.

When will Brits realize that the purpose of ALL official inquiries is to re-affirm that Whitehall's way of doing things is basically sound, possibly requiring a few tweaks but nothing radical? Nobody polishes turds better than the knighted jobsworths entrusted with these futile PR exercises.
