U.N. High Commissioner for Human Rights Navi Pillay is keeping a list of suspected criminals in Syrian war "under lock and key." It is unclear why keeping their identities secret actually helps the victims of their crimes or discourages them from creating new victims.
On May 22, 2014 the UN Security Council is scheduled to discuss a draft resolution circulated by France that would "refer the situation in Syria since March 2011" to the International Criminal Court.
Despite an appeal from 58 countries to all 193 U.N. member states for support, Russia and China are expected to veto the resolution.
