I just dont buy any of it! I really do think it was a tragic case of driver error. If Henri Paul was told to drive fast he would do just that. French police and witnesses have all said none of the reporters were close enough to cause them a problem. Also Henri Paul was meant to be over the limit with alcohol and also had a large does of prescription medication in his system.
I believe it took nearly 2 hours for them to get her out of the car and to hospital and not 2 hours to actually go from the crash site to the hospital. Cutting someone as critically injured as Diana and her bodygaurd were free from a horrific car wreck does take hours, does mean they move things millimetere at a time so as not to cause further injury.
I think for every normal theory their is a conspiracy theory and vice versa, who is to actually say who is right, I doubt we will ever know the truth and the full details of that terrible accident.
