As I listen to the Obama is Awesome crowd spin his gaffe-filled trip to Ireland and Great Britain I am surprised this theory hasn't come up.  Maybe the President couldn't remember what year it was after visiting Buckingham Palace because he became a victim of a vast conspiracy between the Royal Family and the Freemasons.  After all, the head of Scotland Yard's Royalty and Diplomatic Protection Department  is the hereditary custodian of  Rosslyn Chapel.  The ancient church features prominently in The Da Vinci Code and has long been the focus of conspiracy theories revolving around the alleged treasures of the Knights Templar, the Holy Grail and the Sinclair family's ties to the Freemasons
