Contrary to Dr. David Schneider’s claims in an otherwise excellent panel at last week’s Conservative Political Action Conference, Princess Diana was not killed by socialized medicine.

A number of factors were to blame for her death, but the French healthcare system was one of her best chances for survival. Urban legend likes to blame the shameless pursuit of the paparazzi, the hard-partying Dodi Fayed, or even Kensington Palace. But the cause of Diana’s death is actually quite simple: Driver Henri Paul went behind the wheel with three times the legal limit of alcohol in his blood, along with prescription drugs. He drove the car at more than twice the speed limit. And her bodyguard, Trevor Rees-Jones, failed to ensure the princess was wearing her seat belt.
