James Ray has been arrested.

the deaths are very unfortunate.
if anything, let this serve as a chance to learn for others who want to "experiment" with Native American sweat lodge ceremonies, or vision quests, or sun dances or whatever.

James Ray and his staff were not properly trained, and that was dangerous. The lodge was built improperly and it was dangerous.
If someone is NOT an actual card carrying tribal member then likely they are not trained properly. (yes, they have cards)
the only way to be trained is face to face with a tribal elder. Not through books, or websites, or youtube videos. And these days tribal elders are rather picky about who they pass the knowledge onto. Because they really don't appreciate an outsider taking their most sacred beliefs and ceremonies, mixing them with whatever is fashionable at the moment and charging thousands of dollars to exploit their culture.
so please keep that in mind next time someone offers a Native American style "whatever".
