This is the headline over a report in today's edition of The Scotsman. Had it been true, it would have been quite a story. The Director of the FBI Robert S Mueller III has form in relation to Lockerbie: see eg here and here and here and here.
What in fact is happening is that Mr MacAskill is to be the opening speaker at a conference in October at which, two days later, an address is to be given by Kathryn Turman, director of victim services at the Federal Bureau of Investigation, who played an important role making the Lockerbie trial at Camp Zeist accessible to relatives of the victims of Pan Am 103.
This is yet another example of the dreadful decline in The Scotsman's standards. As one of the readers who commented on the story says:
"I believe the Scotsman has won the 'Most misleading headline' prize for the 30th month in a row. Just when you think the Scotsman can't sink any lower; it is a dreadful shame that a mighty newspaper has been dragged into the gutter."
