Abdel-basset al Megrahi is almost certainly not the Lockerbie bomber. The real question is not why he was released but how his sham of a trial ever resulted in a conviction - and who was actually behind the Lockerbie bombing - not to mention why
There has been a lot of self-righteous talk from politicians on both sides of the Atlantic recently about “demanding the truth” about whether BP used it’s influence to get Megrahi released.
This is either based on ignorance of the facts or else is extremely hypocritical given the utter silence of most of the people involved on the truth about the Lockerbie bombing and Megrahi’s trial, which was a politically influenced sham from the start, in which key witnesses were bribed and coached in and advance and evidence was tampered with.
That’s before getting to the issue of the very likely links between a US warship (the USS Vincennes) shooting down a plane full of hundreds of Iranian civilians in the Persian Gulf, all of them killed, just like the civilians killed in the Lockerbie bombing, less than a year before Lockerbie.
Some people at this point claim the Vincennes shooting down the Iranian Airbus was an accident. It may well be that the Vincennes’ crew wrongly thought the Airbus was an Iranian military plane. It’s also the case that they had un-necessarily crossed into Iranian waters to deliberately provoke a fight with Iranian ships though – and that the captain of the Vincennes was negligent in using his radar incorrectly.
The families of the Iranian civilians killed in this incident have never had any apology. The crew all got service medals.
This definitely does not make the murder of hundreds of other civilians in the Lockerbie bombing right or justified – anything but – but it does make the more myopic demands for “the truth” about Megrahi’s release ring very hollow.
The focus on BP alone is also pretty hypocritical as plenty of American oil firms were back in Libya before BP was.
So President Obama can claim to be "surprised, disappointed and angry" about Megrahi's release and Prime Minister David Cameron can claim it was wrong to release "this mass murderer", but both either need to study Megrahi's trial and all the political manipulation of it - along with the link to the Iranian Airbus shot down by a US warships - or else they're being a lot less than honest.
