UNDERTAKEN FOR THE CANADIAN LAW REFORM COMMISSION, THE STUDY REVEALS THAT ONLY ABOUT A THIRD OF DSO'S THREATEN OR ACTUALLY ENDANGER THE LIFE OF THE VICTIM. THE ROLE OF PSYCHIATRISTS EMPLOYED BY THE GOVERNMENT TO SECURE AN INDETERMINATE SENTENCE IS DESCRIBED. MOST DID NOT DECLARE THEIR ROLE AS DOUBLE-AGENTS. IN THEIR TESTIMONY BEFORE THE COURTS, THEY FAILED TO DISCRIMINATE BETWEEN FACT AND PERSONAL OPINION, AND THEIR INDIVIDUAL PREJUDICES OFTEN SURFACED. THE LIFE OF DSO'S IN CANADIAN PENITENTIARIES IS LIKELY TO BE BRUTAL. FOUR HAVE BEEN MURDERED WHILE IN CUSTODY AND OTHERS HAVE ATTEMPTED OR COMMITTED SUICIDES. IT IS UNETHICAL FOR PSYCHIATRISTS TO PARTICIPATE IN A PROCEDURE CAUSING HARM OR DEATH TO AN INDIVIDUAL. THEREFORE, THE CANADIAN PSYCHIATRIC ASSOCIATION IS URGED TO SUPPORT THE LAW REFORM COMMISSION'S CONDEMNATION OF THE PRESENT DSO LEGISLATION AND IT IS SUGGESTED THAT PSYCHIATRISTS NOT COLLABORATE IN DSO CASES.
