"Facilitated Communication" is totally bogus. In every properly constructed test where the information being requested of the subject is NOT shared with the "facilitator", the subject's "response" is virtually always invalid/incorrect.
At best, the claim that the "facilitator" is simply "steadying the hand(s)" of the subject is purely wishful thinking. At worst, it is outright deception. Either way, it is worthless.
A great demonstration of the properly blinded test was included in an episode of Law and Order called "Cruel and Unusual": http://www.imdb.com/title/tt0629222/
