This piece is written in such a way that it is difficult to ascertain the precise facts. Some of it has a vague "where there's smoke there's fire" quality, and I'd like to know more about the fire concerned.
Nonetheless, my hackles rise at the prospect of a government health service, such as the National Health Service in the UK, treating exorcism as a legitimate form of psychiatric therapy. British readers might want to look into this further, ask some questions, and try to establish what the hell (as it were) is going on here.
