As al-Megrahi, the only man convicted of the Lockerbie bombing, nears the end of his life, this al-Jazeera investigation (first broadcast in June) is worth another watch.
Scottish private investigator George Thomson sidesteps the politics, conspiracy theories, alternative suspects and suchlike and concentrates on the two areas of evidence that were used to convict al-Megrahi.
1) Witness Identification
2) Forensic Evidence.
There was only one witness: Tony Gauci, the Maltese shopkeeper who identified al-Megrahi as the person who bought the grey Slalom shirt which the timer fragment was allegedly found embedded in.
There were only two scraps of forensic evidence to link al-Megrahi to the bombing: the MEBO timer fragment and the piece of grey shirt it was allegedly found embedded in.
Make up your own minds whether the only witness and the two scraps of forensic evidence were genuine or corrupt.
This is investigative journalism of the very highest order.
