B makes a good point re the difficulty of who would do such studies. However there is some hope in that such studies need not be too expensive; one model might simply look for suicides or attempts that occurred during or shortly after “treatment” by anyone who was not suicidal previously. I am aware of at least one person and possibly two, and would suppose there might be readers here who do also. Another angle would be find out what percentage of persons who made successful attempts had undergone unwanted “treatment”. Perhaps someone can suggest a way to put such an inquiry together using volunteers and some help from academia or other credible figures or agencies.
