In the article, "Forensic Psychiatry Patients Are Ill Not Evil - And We Should Stop Hiding Them", Kastner shares his experiences within the field of forensic psychiatry and argues that the way the media portrays these individuals and the way in which they are kept hidden from society only perpetuates stigma and fear.
Kastner has made a number of documentaries, but in the last few years he has been focusing mostly on the Canadian justice system and mental illness. In 2013, his film "NCR: Not Criminally Responsible was released, which looked at the "personal impact of the mental disorder defence in Canada" and showcased the story of Sean Clifton, a man who repeatedly stabbed a woman in a shopping mall while in a delusional state. This May, another of Kastner's documentaries called "Out of Mind, Out of Sight", which follows "the cases of four patients at Brockville [Psychiatric Hospital] who committed violent acts" including Michael Stewart, will also be released.
