Dealing with terrorism is a potentially hazardous but relevant extension of the role of the forensic psychiatrist. Psychiatrists may be asked to act as intermediaries between terrorists and the State or as forensic experts in courts. They also treat victims of terrorism or imprisoned terrorists. Terrorist-patients are a particularly difficult clientele because they should not be treated in unsecured forensic psychiatry hospitals due to their proven danger to staff and other patients; facilities should be sought in the prison system. However, to avoid being perceived as policemen, jailers, or collaborators, forensic psychiatrists should seek the formal approval of the medical profession so that there is no question concerning their professional identity. Psychiatrists should also avoid naive interaction with the media by appropriate governmental briefing. There is much that psychiatrists can do to help the victims of terrorism, including assessment, rehabilitation, and presentation of medicolegal evidence.
