Inquests into the deaths of Diana, Princess of Wales and Mr Dodi Al Fayed

I'm sure Mohamed Al Fayed has his reasons, and the public have their own reasons for being interested in the outcome of the inquest into Diana's death, but allow me to answer the conspiracy question using my skillset.

First this:

Only Princess Diana's bodyguard, Trevor Rees-Jones, survived the crash.

Secondly:

Among the questions Lord Justice Baker put to the jury was whether Diana and Mr Fayed would have survived had they worn seatbelts and whether Diana would have lived had she been taken to hospital more quickly.

The only person wearing a seatbelt was Trevor Rees Jones.

The only person to survive the crash was Trevor Rees Jones.

Therefore the only fair conclusion is that Diana, Dodi and Henri-Paul died as they were not wearing their seatbelts.

Conspiracy theories:
My favourite:

Claims that the seatbelt which would have saved Princess Diana's life was sabotaged are now being investigated by detectives

There is no argument that Diana was not wearing a seatbelt (All agree she wasn't. There is no suggestion she was wearing one that then failed in the accident). So the suggestion that the party of four got in the car only to discover that 1 out of 4 belts were serviceable, yet thought "oh hell, we'll just go anyway and drive hellishly fast while at it..." is nonsense.

In summary: Occam's Razor applies.

All other things being equal, the simplest solution is the best."
