Which is why he has $3,000,000 stashed away, courtesy of (presumably) Quaddafi.What's being said is that the evidence on which Megrahi's conviction was based does not in fact, establish his guilt beyond reasonable doubt.
You know, because Quaddafi just cannot stand someone being falsely accused of some crime, and felt a deep, emotional need to compensate him for the horrible injustice.
Anyway... again: if you, Mycroft Holmes-style, managed to show this man's innocence without ever leaving your computer's chair, then please take this to the authorities. Demand a retrial. Start a petition. A man had been convicted of a horrible crime without doing it -- and you're silent? Where have you been until now?
