Report: U.S. bugged Princess Diana’s phone
The Central Intelligence Agency was bugging the telephone conversations of Britain's Princess Diana on the night she died, a British newspaper reported.
For as much as I've delved into this subject, I have never heard this before. Wow.
Let's not be forgetting that the 85 cameras (forgot the exact amount but it was 80 something) were apparently not working, where have we heard that before, and it took the ambulance 1hr 15min to travel the 3 odd miles to a hospital.
"...and it took the ambulance 1hr 15min to travel the 3 odd miles to a hospital."
They needed time to clear out the hospital so they could switch out Diana with the dead body double. <just kidding!>
