It's to cover up the misdeeds of people in very high places ie the "establishment", in this case, I believe many MPs who at the time, were high up in the Labour party and or the Scottish Labour Party. The likes of Gordon Brown, who's a widely reported paedophile, George Robertson (high ranking Labour and ex NATO Secretary General) was the signatory on Hamilton's gun license application, and God knows how many others. It was reported that Brown's credit card appeared on the same list as Pete Townshend of The Who when the plod did their huge online child porn sting years ago. I think Alan Milburn's appeared on it to. He was required to resign from the Labour government "to spend more time with his family".
