I knew Scientology was in trouble when the media moved on from the usual silly gossip about its celebrity members to much darker, disturbing issues at the heart of the movement – issues, as I have come personally to understand, that actually matter, Jonny Jacobsen writes in Herald Scotland.

After a Paris court last month convicted several Scientologists and two organisations associated with the movement in France of organised fraud, and amid other investigations in France looking at a suicide and an alleged abduction, Oscar-winning film-maker Paul Haggis, a long-time member, quit Scientology.

Haggis, who wrote and directed Crash, denounced the practice of “disconnection“, which sees members forced to cut off contact with anyone – even their loved ones – if they are deemed an enemy of Scientology.

In Edinburgh in the early 1990s, I found out just what the practice of disconnection could do to ordinary people when a close friend became involved in Scientology. It was an experience which marked me so profoundly that I have been tracking the movement ever since…

Paul Haggis, the Hollywood film director, has resigned from the Church of Scientology after 35 years as a member in protest against its apparent opposition to gay marriage.

In his letter Haggis also highlights a lie told by Scientology spokesperson Tommy Davis, who in an interview with CNN denied Scientology’s policy of disconnection — in which the destructive cult forces some of its members to sever relationships with friends and family members. [video]
