The person invariably referred to as the Lockerbie bomber in all reports of the tightly controlled US media is certainly entirely innocent of that particular attack.
What happened is as follows:
An American warship, the USS Vincennes, brought down an Iranian civil airliner killing all of the hundreds of passengers aboard. Far from any criticism, the crew were awarded US Congressional medals of honor for their efforts.
The Persians have never been noted for their forgiving nature, and usually take the view that a bloody nose for an attacker discourages repetition, and put out a contract for a tit for tat. The contract was taken up by Abu Nidal, one of many shadowy Palestinian groups, and successfully carried out.
When the US airliner came down over Lockerbie in Scotland, US teams flew in immediately and isolated the entire area. They came up with a small electronic part, said to be the trigger of the explosion that brought down the plane, but the shady past of leaders of the effort forces some skepticism.
In the court case that followed the only witness against Megrahi, a Maltese shopkeeper, was unable to identify Abdel Baset Al-Megrahi, who was sitting in the court, as the man who bought stuff from him in his shop in Malta.
The Maltese shopkeeper, the only evidence against Megrahi, was paid many millions of US dollars for his testimony.
If the proposed re-examination of the case against Megrahi had gone ahead, there seems no doubt that the case against him would have fallen apart.
Megrahi’s exact physical state, whether he is at death’s door or in good health, is irrelevant.
