I would like to thank Edwin Bollier, founder of MEBO Telecom, who just sent me a short video (extracted from the Gideon Levy’s documentary “Lockerbie Revisited”).
Richard Marquise is the FBI agent who led the US side of the Lockerbie investigation.
At 2.45, you can watch the following exchange:
Levy: Would you have a case without this piece of evidence [PT/35(b)]?
Marquise: It would be a very difficult case to prove. […] I don’t think we would ever have had an indictment.
Watch the video.
