Bhopal - Blame it on the system!

Yesterday in an NDTV program on the Bhopal disaster verdict, the one conclusion that came through is to blame it on the system! Who designs systems? Cannot the government strengthen the systems? It is a travesty of justice for the Bhopal Victims. In 2004, on the 20th anniversary of the Bhopal Disaster, I met (Late) Ms Carolyn Meritt, then Chairperson of the CSB, at IIT Kanpur. She asked me one question, which I could not answer. Why is the PSM system not mandatory in India where Bhopal occurred? I am still looking for answers. See this youtube video on the reaction of Sathinath Sarangi, a bhopal activist.
