On November 13, 2006, Human Rights Watch published a briefing paper on torture in Chechnya that it had prepared for the 37th session of the United Nations Committee Against Torture. The paper covered torture by personnel of the Second Operational Investigative Bureau (ORB-2), torture by units under the effective command of Ramzan Kadyrov, torture in secret detentions, and the continuing "disappearances." According to HRW, torture "in both official and secret detention facilities is widespread and systematic in Chechnya." In many cases, the perpetrators were so confident that there would be no consequences for their abuses that they did not even attempt to conceal their identity. Based on extensive research, HRW concluded in 2005 that forced disappearances in Chechnya are so widespread and systematic that they constitute crimes against humanity.
