CaptainMyCaptain I always thought that, if you were trying to bump someone off, you would choose a more reliable method than getting a load of people on scooters to chase their car, which they weren't even driving at the time, in the vague hope that the driver would go a bit too fast and crash, and that it would prove to be fatal.
I don't think she was mentally unstable, but she did have mental health problems and she struggled with being under that level of public scrutiny. I think at the time, there hadn't been that kind of media interest in any Royal spouses, the press were more likely to be "respectful" and keep their distance, but things had started to change during the 70s and Diana couldn't really have predicted how much intrusion there would be into her private life. If she handled that badly, I think you could argue that there wasn't any real precedent for her situation at the time. I also think that, since she died, people have tended to forget that she was criticised on an almost daily basis in the papers for one thing or another. Not that she should have been immune from criticism, of course, but the barrage must have been pretty overwhelming. I felt sorry for her at the time, and I can understand why Harry is getting stroppy about the way his wife is treated.
Still a republican, by the way!
