The state legislature of Connecticut is now looking at more strictly regulating hypnosis after hypnotist Michael Johnstone videotaped himself having sex with six clients -- all of whom were apparently hypnotized. But Johnstone was basically given a slap on the wrist:

...British hypnotist Michael Johnstone was sentenced to 90 days in prison and later deported to England this year for having sex with a half-dozen patients and videotaping the trysts. The patients went to his office in Milford for anxiety treatment between 2000 and 2003.

Johnstone pleaded no contest in January to three counts each of reckless endangerment and breach of peace [as part of a plea agreement]. He also agreed not to work as a hypnotist.

"Reckless endangerment?"
