Whittamore is (or was) emphatically part of the wider problem, rather than just Coulson - as the report states the Mail and Mirror used him a lot more than the NOTW did, so one wonders whether this will ratchet up the pressure on Coulson at all.
God knows what he is whinging about though, anyone else who had directed as much corrupt activity as he is alleged to have done (and indeed was convicted of - he got access to the PNC via a CAD operator at Wandsworth) would be looking at a far more substantial prison sentence than the two years suspended sentence he in fact recieved.
