[T]here is at least one organization that is successfully exposing spiritual chicanery -- the Dallas-based Trinity Foundation.
Ole Anthony, a prophet with a private detective's license, has successfully exposed the shenanigans of Robert Tilton, W.V. Grant, Benny Hinn and Larry Lea.
Reading about Ole Anthony reminds me of Randi's The Faith Healers. If they were both a couple of decades younger they could team up and give preachers and faith healers hell on earth (not that they haven't given them a taste of it already).
