How big a problem is torture? Are the right things being done to prevent it? Why does the United Nations appear at times to be so impotent in the face of it? Drawing on his ten plus years of experience as Chair of the UN expert body visiting places of detention in countries around the world in order to ‘tackle torture,' Sir Malcolm will tell the story of torture prevention under international law, setting out what is really happening around the world. Challenging assumptions about torture’s root causes, he will give a frank account of what has been done, what can be done and – most importantly and controversially, what is not being done, and why.
