There's serious question marks over two of the key evidence used to convict Megrahi. The "Malteses shopkeepers" evidence has largely been discredited, plus he is supposed to have been paid several million dollars by the FBI, the timer that was supposed to have been used has reported not to have been of Swiss/Libyan origin like was originally claimed, and again the witness was offered money by the FBI.

The whole thing reeks of a coverup and Megrahi being a patsy to serve the US, UK and Libya's needs, whilst at the same time ignoring the truth. It's a shame it's ended the way it has, with Megrahi withdrawing his appeal, it's conviently saved the UK/US a lot of embarassment.
