Yes...The fact that both Princes still have lingering doubts about the car crash 10 years ago spoke volumes. So much for it is just an accident train of thought.

"I don't know, for me personally what happened you know that night, whatever happened in that tunnel -- no one will ever know. " He doesn't say it's not an accident, just that he doesn't know how things unfolded in the tunnel...
Prince William (when asked "So then in some ways you probably understand the public fascination with this inquiry.":
"Yeah, but at the same time there's a lot of people feeding it, and unnecessarily, I might add. You know -- to the whole sort of conspiracy side of things. And there's always rumors and stuff that were brought up the whole time." Once again, no indication that he disagrrees with it being an accident, quite the contrary.
