The Express interviewed a retired British Special Forces soldier, Bob Stirling, as to how Princess Diana might have been assassinated by the SAS.
From “How rogue SAS would murder Princess Diana”:
“Using specially trained handlers, covert reconnaissance and a laser light to force Diana’s chauffeur-driven limousine off the road, the rogue death squad could not only have successfully completed their deadly mission, but made it look like a road accident.
“‘We are taught that a target is at its most vulnerable when in transit,’ Bob said. ‘In this instance it was know the target used a Mercedes to travel around Paris.’
“‘The car was the weak spot in their security, and the driver, Henri Paul, was the weak spot in the car because driver error is difficult to disprove, whereas mechanical tampering may be discovered later.’
“The operation would have begun with a period of surveillance. ‘It would not be difficult, as their field operators would be assumed to be paparazzi,’ he said. ‘The car would be tagged with an electronic tracer and its movements monitored so that regularly used routes could be found and reconnoitred.’
“He said that along these routes several places would be selected ‘where the car would be driving quickly into a bend or where leaving the road would meet a solid obstacle such as a concrete pillar.’
“A separate team would have studied the driver’s habits.
“‘During the preparation phase a method would be discovered by which someone, probably a female operator, could add extra alcohol to the driver’s usual drink.’
“To ensure the car was traveling fast enough to be deadly, a ‘pressure car’ could be used to fluster the driver, who could be expected to react impulsively under the influence of alcohol. Evidence from the inquest showed the car was traveling at 62 mph, twice the speed limit, when it entered the Pont de l’Alma tunnel.
“Traces of paint and debris indicated there had been a collision between the car and another vehicle, thought to be a white Fiat Uno which has never been traced.
“‘The coup de grace would have been the laser,’ added Bob.
“‘A motorcycle would be the most reliable means and the least likely to be discovered,’ said Bob. ‘On the day, the target vehicle was harassed by paparazzi motorcycles. A motorcycle with two people on it might appear to be paparazzi.’
“‘It could pass the target car just before one of the selected killing areas and the passenger could attract the target driver’s attention with a false brake light, then blind him with a laser built into a camera as they approached a suitable spot. There were reports of bright flashes from the the time of the event.'”
