Inquest Into The Death Of Princess Diana?

Deliberately causing an accident is a very clumsy way of committing murder.How could 'they' know if the result would be fatal?How would 'they' know that Diana & Dodi would not be wearing seat-belts,or the driver would travel at such speed? There are far too many improbables to make a case for murder.It was a preventable accident,plain & simple.
