The opening line of the famous song by David Gates holds a lesson for us all.
Here are three photographs.
The first is of the fragment of timer circuit board said by the prosecution to have been found at Lockerbie.
Photographs two and three are of annotations written by Allen Feraday, the forensic officer on whose forensic report the Lockerbie verdict of Guilty was founded.
Photograph two is of his note dated 1st August 1991 concerning the above fragment. The words are "Plating on the two thin lines is of pure tin (Cu [copper] breaking through from underneath. Alan F.)"
The third is of his note on the same day concerning a set of circuit boards sent to him for comparison by the Swiss company Thuring. The words are "Tinning on the thin tracks is of 70/30 sn/pb [tin/lead]. However this may be dipped or roller tinned on top of either the Cu tracks? or the Cu tracks with a layer of pure tin? Alan F."
There is a clear metallurgical difference between the two items. Feraday indicates some puzzlement as to why this may be the case, hence his two question marks.
But did he draw this difference and his two questions to the attention of the judges in the Lockerbie trial?
No. He stated with absolute certainty:
particular tracking pattern of the fragment has been extensively compared with
the control samples of the [Thuring] MST-13 timers and circuit boards and it
has been conclusively established that the fragment materials and tracking
pattern are similar in all respects to the area around the connection pad for
the output relay of the `MST-13' timer.”
"Conclusively established ... materials and tracking pattern similar in all respects ..." Ten simple words. Yet on this false statement a man was condemned to a lifetime of imprisonment.
What was the origin of the Lockerbie fragment? Who made it, where and when? It clearly did not come from Thuring and was not from the batch sold to Libya in 1985. Whatever its origin, it contradicts the unique central feature of the prosecution case.
The Scottish Crown Office continues to stonewall the nation and Scottish Government by pronouncing that this evidence can only be considered in a court of law. Well, here are the pictures. Please judge for yourself.
