Why was the US tapping Princess Diana's phone?

The resulting information to be revealed by Lord Stevens detailed report on Diana's violent car crash death, and the events that led to it are coming to light. The most shocking bit of information is that according to news sources like the Sunday Observer and the BBC - the American secret service was bugging the phone lines of the Princess. The "whys" of it remain a mystery still.

The Sunday Observer states the bugging had no approval from any British secret service authorities on the fateful night the young Princess was killed in the car accident. What was also found to be true was that her driver was drunk when he took the wheel.

This shocking revelation about the possible reasons why an American secret service would be tapping into Diana's life and surveilling her remains unanswered. It is sparking new dialogue regarding the international code of rules and conduct between sovereign nations regarding the right to spy on individuals without any lawful protocols.

The Sunday Observer reports that "Stevens is understood to have been assured that the 39 classified documents detailing Diana's final conversations did not reveal anything sinister or contain material that might help explain her death."

In the upcoming report Stevens's theory is that Diana, her boyfriend at the time, Dodi Fayed, and the French driver died in an accident caused by the driver speeding through the Pont de l'Alma underpass in Paris while drunk, and losing control of the vehicle. The car was being followed by paparazzi.

The Stevens report is said to prove the numerous conspiracy theories wrong. Diana was not pregnant or planning nuptials with Dodi, son of retailer and outspoken entrepreneur Mohamed Fayed.

There is still the mystery unsolved of a possible white Fiat that left paint on the struck vehicle that carried the Princess, but allegedly has never been recovered.
