In order for anytype of deprogramming the person must want to leave these beliefs or has an understanding he has been deceived....until then the question is how do families and loved ones deal with the situation as it is.
Baker Act, psychiatric evaluation, deprogramming, therapy.
Ummmm..., okay then ... how does that work for a "non-Christian cult group" like Jehovah's Witnesses then? Or how does it work for another "non-Christian cult group" -- like Mormonism. Or another "non-Christian cult group" like Islam.
In other words, unless you're thinking of some application of these things you mentioned -- in ways that I don't understand -- I don't think what you're saying with the Baker Act, and psychiatric evaluation and such, would help in the least with Jehovah's Witnesses, or Mormons or Muslims -- at all...
And if it wouldn't help with those, like Jehovah's Witnesses, or Mormons, or Muslims -- I'm not sure how it would help with "New Agers/UFO enthusiasts" ... LOL ...
