If you read this brillliant article by Richard Littlejohn about Mandelson,you may well be left with the suspicion that he went on holiday with Gaddafis son and when he got back he rang up Scotland and told them to let the lockerbie bomber out.
He was convicted of the worst terrorist atrocity the UK has ever seen and should have spent the rest of his life in prison.If his conviction was unsafe,it should have been proven so at appeal,that is due process.What happened today makes a mockery of justice,agin. 
EDIT.It was not an act of war between two warring countries,it was purely an act of terrorism ,they are far from the same thing.Apart from anything else,rules of engagement in war forbid the deliberate targetting of innocent civilians.The only targets in this act were innocent civilians.
How about Albs the innocent civilians on the Iranian airliner, or the innocent civilians killed during the F111 Libyan bombing raid, all enacted by the USA?
I will not defend terrorism, but are our own states innocent of such acts? NO is the answer, and Lockerbie, no matter how unpalatable it was and still is (yes for me as well!) was an act of retailation by countries attacked by the US. We in the west may see it as terrorism, but 'on the other side' it is seen as fighting for their freedom. If you sow the wind..................

Let all our nations now go for jaw, jaw, jaw and not war, war, war as Churchill recommended.
