Louis Theroux

By Reason of Insanity (1) (1x23)

:

Louis immerses himself in the world of Ohio's state psychiatric hospitals, meeting patients who have committed crimes - at times horrifically violent - while in the grip of severe mental illness. They have been found not guilty by reason of insanity and ordered by the courts to secure psychiatric facilities to receive the treatment that it is hoped will, one day, lead to their reintegration back into society.
