Exorcise causes brain damage?

The Exorcism of Emily Rose opens in theatres today. This page usually rolls his eyes at these kinds of movies, but Sony Pictures promotional campaign caught my attention, and refuses to let go.

In one of the 'Emily' trailers, Sony uses the phrase phrase "based on a true story". Those of us jaded by the reality TV of Big Brother, Survivor, and Weapons of Mass Destruction in Iraq understand that "based on a true story" can mean just about anything. In this case, it refers to the Roman Catholic church actually recognizing the demonic possession of a 19 year old woman a few years ago, and the court case that followed after Emily died during the course of the exorcism.

The true part is more than likely the court case, but Sony mentions nothing about that part in the trailers, just the scary possession/exorcism stuff. Are they trying to pass off Demonic Possession is a "true" story, or is Sony just pandering to the winners of America's culture wars? A lot of Conservative Catholics have joined their Evangelical soulmates in believing those bedtime stories about demons, angels and that Saddam was in on 9/11. And didn't the Catholic Church also bring us such wonderful fables as "Your World is Flat", "Latex Ticket to Hell", and "Never Touched an Alter Boy"?

In the real world, "true" implies an objective standard, not the imposition of one's beliefs, be it Angels, Goblins, Trolls, Gnomes, Orks, Sith Lords, Republicans, or Demons. 'Emily' may have thought she was possessed, but a 15-year-old Japanese schoolgirl falling down a well doesn't make InuYahsa a true story either.
