Back in 2009 (see here, here and here), as the authorities prepared to release the so-called Lockerbie Bomber to return to Libya, ostensibly on compassionate grounds, I came across a blog by Scottish law professor Robert Black. The latter, together with Jim Swire (father of one of the victims) smelt a rat.
Some suspect that not only was the wrong man accused - the wrong country, even (the operation may have been Iranian) - but that there was a deliberate miscarriage of justice and a cover-up, and that Al-Megrahi was sent home to prevent a retrial that would blow the whole affair wide open.
Now (hat-tip: Ian Parker-Joseph) Scottish newspaper The Sunday Herald has published a 5-year-old, hitherto secret legal review of the case, which they say contains evidence that could well have led to Al-Megrahi's conviction being overturned. The link to the (slightly redacted) 800-page text is here.
This is a bad day for the reputation of the Scottish legal system, especially when (as Parker-Joseph does) one is tempted to rope in outstanding concerns about the 1996 Dunblane massacre and alleged child abuse victim Hollie Greig.
Time for a full public enquiry - no "safe pair of hands", please, no cripplingly narrow terms of reference, full power of subpoena, all evidence on oath and no prior indemnification against prosecution for perjury or other perversion of the course of justice. And later, possibly, a huge action for damages by Al-Megrahi and his family.
And then let's see what else needs to be cleared from the Augean stables.
