[The following are excerpts from letters published in today's edition of The Guardian. There are no letters taking a contrary view.]
(a) I support President Obama's call for "all the facts to be laid out" regarding the Lockerbie affair ... He should be reminded that the Montreal convention of 1971, enacted under the UN-linked International Civil Aviation Organisation, was the proper legal instrument to address the terrorist bombing of flight PA 103 over Lockerbie. The US, resenting the convention provision that the two suspects could be tried in Libya, orchestrated UN sanctions in an attempt to force their surrender to an American or British court... The conviction of Abdelbaset al-Megrahi was a farce. Even Lord Sutherland, presiding over the arbitrarily contrived Scottish court in Holland, emphasised the "uncertainties and qualifications" in the case, referred to parts of the "conflicting" evidence "which might not fit" and to a conclusion "which is not really justified". The US ignored international law, imposed sanctions on Libya which resulted in 16,000 deaths, and orchestrated a blatant miscarriage of justice.
(b) As politicians in both Britain and the US queue up to comment on the release of Megrahi, they remain silent about the need for an inquiry into the atrocity itself. To deny the families of the 270 victims of Lockerbie an investigation into this gross act of terrorism is an international disgrace, and the failure to seek to identify those responsible encourages more acts of terrorism... David Cameron should call for an independent inquiry led by the UN to find out the truth about Pan Am Flight 103.
(c) However appalling the bombing of Pan Am flight 103 was, and if Libya were responsible, at worst Megrahi was following orders. That doesn't excuse his putative actions, but it is then hard to identify a moral distinction between his behaviour and eg that of the USAF aircrews attempting Gaddafi's assassination in the US bombing raid on Tripoli that killed 59 people, including Gaddafi's adopted daughter, or the behaviour of the (subsequently decorated) captain of the USS Vincennes when he shot down Iran Air flight 655 in 1988, killing all 290 passengers and crew. David Cameron has no business trying to curry favour with the US administration by criticising the lawful and probably just decision of the Scottish justice secretary Kenny MacAskill to release Megrahi on compassionate grounds.
(d) In all the hype about releasing Megrahi, one crucial fact seems to have got submerged. He was about to appeal with new evidence, and very likely win, when "persuaded" to abandon the appeal and be sent home "on compassionate grounds". Cynics might think this was to avoid the embarrassment of the court deciding that all along they had the wrong man. A case where two wrongs make a right?
