There are good reasons to believe that the conviction of Megrahi was a shameful miscarriage of justice

[What follows is excerpted from an article by Kim Sengupta published today on the website of the Belfast Telegraph (and a week ago behind a paywall on the website of The Independent):]

Abdelbaset al-Megrahi lay in his bed attached to a drip, on red sheets stained by dark splashes of blood he had coughed up. An oxygen mask covered his skeletal face; his body twitched as he drifted in and out of consciousness. He was in the advanced stages of cancer: medicine he desperately needed had been plundered by looters; the doctors who had been treating him had fled.

This was in Tripoli in the winter of 2011, in the turmoil of Libya's civil war and the chaotic aftermath of the fall of Muammar Gaddafi. It was a time of great violence. A dozen bodies were piled up beside a roundabout a half-mile from where I had seen Megrahi lie slowly dying. They were corpses of black men, lynched by the rebels because they were supposedly mercenaries fighting for the regime. In reality, they were victims of a xenophobia against African migrants which had accompanied the uprising.

Megrahi himself had been convicted of a dreadful massacre; of being responsible for 270 deaths on December 21, 1988, when Pan Am Flight 103 blew up over the town of Lockerbie in Scotland. A bomb - 12 ounces of Semtex in a Toshiba radio-cassette player - had been secreted in the luggage of the plane carrying passengers to the US, many returning home for Christmas.

After spending eight years in Scottish prisons following his conviction, Megrahi had been returned to Libya on compassionate grounds following a diagnosis of prostate cancer. After a few months in prison in Tripoli, unable to walk and bedridden, he was allowed to return to his family home.

There was vengeful anger expressed by some in Britain, and more so in the US, at Megrahi's return to Libya. He had faked his illness, it was claimed, and even if that was not the case, he had escaped justice by not actually dying in a cell.

The charge of subterfuge was reinforced by the perception that his release was part of the many dodgy deals between Tony Blair's government and Colonel Gaddafi's regime.

Yet there are good reasons to believe that the conviction of Megrahi was a shameful miscarriage of justice and that, as a result, the real perpetrators of one of the worst acts of terrorism in recent history remained free. That certainly was the view of many, including international jurists, intelligence officers, journalists who followed the case, and members of bereaved families.

Among the latter group was Jim Swire, who lost his daughter, Flora, in the bombing. Dr Swire, a man of integrity and compassion, who became a spokesman for UK Families 103, stressed that "the scandal around Megrahi is not that a sick man was released, but that he was even convicted in the first place. All I have ever wanted to see is that the people who murdered my daughter are brought to justice".

Megrahi died in May 2012, a few months after I had seen him. Yet a campaign Dr Swire had helped set up, Justice for Megrahi, continues to help the Libyan's family to seek a new appeal against the sentence in their efforts to posthumously clear his name.

Certainly, the chronology of the original investigation into the bombing is strange, raising serious questions about the official narrative.

Soon after the downing of the Pan Am flight, American and British security officials began laying the blame on an Iran-Syria axis. The suggested scenario was that Tehran had taken out a contract in revenge for the destruction of an Iranian civilian airliner (Iran Air Flight 655), which had been shot down by missiles fired from an American warship (the USS Vincennes) a few months earlier.

The theory went that the contract had been taken up by the PFLP-GC (Popular Front for the Liberation of Palestine-General Command), which specialised in such operations.

The blame switched to Libya - which was then very much a pariah state - around the time Iran and Syria joined the US-led coalition against Saddam Hussein in the first Gulf war.

Robert Baer, the former American intelligence officer and author, was among those who held that an Iranian-sponsored hit was the only plausible explanation for the attack. This was the firm belief held "to a man", he stated, by his former colleagues in the CIA.

After years of wrangling, Megrahi, the former head of security at Libyan Airlines and allegedly a Libyan intelligence officer, was finally extradited in 1999 - along with another man named as a suspect over the bombing, Lamin Khalifa Fhimah, also allegedly employed by Libyan intelligence. (...)

I covered their trial at Camp Zeist in the Netherlands, which took place in a specially constituted court, with a panel of Scottish judges but without a jury, under Scots law. The two men were effectively charged with joint enterprise - conspiracy - yet only Megrahi was found guilty. (...)

The prosecution evidence was circumstantial, details of the bomb timer on the plane were contradictory, and the testimony of a key witness, a Maltese shopkeeper, was extremely shaky under cross-examination.

Five years on from the trial, the former Lord Advocate, Lord Fraser of Carmville, who had been responsible for initiating the Lockerbie prosecution, famously described the witness, Tony Gauci, as "an apple short of a picnic" and "not quite the full shilling".

The performance and evidence of a supposedly prime CIA intelligence asset, Abdul Majid Giaka, codenamed Puzzle Piece, who turned up in a Shirley Bassey wig, was widely viewed as risible. It emerged later that important evidence had not been passed on to the defence lawyers. Ulrich Lumpert, an engineer who testified to the validity of a key piece of evidence, admitted later in an affidavit of lying to the court.

The observer for the UN at the trial severely criticised the verdict, as did many lawyers. Robert Black, a law professor born in Lockerbie, who played an important role in organising the Camp Zeist proceedings, later became convinced that a great injustice had taken place. (...)

Fr Patrick Keegans had just been appointed as parish priest in Lockerbie and was looking forward to his first Christmas there at the time of the crash. His tireless work with the traumatised community drew wide praise and is remembered with gratitude.

He reflected: "For those of us who experienced Lockerbie, the story will never come to an end. Lockerbie lives with us, we are part of Lockerbie and Lockerbie is part of us... the horror, the tragedy, the sadness, the grief, the support and the love that was shown - all of that stays with us."

Fr Keegans, who is now retired, joined the Justice for Megrahi campaign after meeting the convicted man's family and is now backing the call for a fresh appeal.

"I can't live with myself being silent," he explained, "when I'm truly convinced that this man has been unjustly convicted. Lockerbie is an unfinished story as far as the legal aspects are concerned."

Megrahi died at his home in Tripoli, still protesting his innocence. He thanked Dr Jim Swire and others who had believed in him.

In his final days, he said: "I pray for all those who died every day. I shall be meeting my God soon, but the truth will come out.

"I really hope the truth of what really happened will come out one day."
