Of course The Exorcist wasn't about to open only in Chicago. In an eerie display of synchronicity, a few days before Tucker's story broke, Pope John Paul II had attempted an impromptu exorcism of a hysterical young woman who'd been screaming insults at him in Rome. The return of the movie guaranteed the incident headlines everywhere. Newsweek also interviewed LeBar and posted the conversation on its Web site. Some cases take a very long time.
Demons are very stubborn.
LeBar claims to have performed about 40 exorcisms. Newsweek asked him if The Exorcist was phenomenologically on the money. I've never seen any high levitation though. I've never seen any spitting up of material. The press appreciates experts who refuse to sensationalize.
