(e) Authorize the verification by United Nations-led teams of the presence of children in military camps, training centres and detention centres, as agreed by the State party in May 2008 during the visit of the Special Representative of the Secretary-General for Children and Armed Conflict; (f) Ensure that refugee camps and sites for displaced persons are of a civilian and humanitarian nature and increase the security and protection of civilian populations both within and around them, given that such measures help in preventing the recruitment of children and in protecting them. Training on the prohibition of torture (35) While acknowledging the State party’s significant efforts to provide human rights training to public officials, the Committee is concerned that the information, education and training provided to military and law-enforcement personnel and prison staff, army personnel, judges and prosecutors are inadequate and do not cover all the provisions of the Convention, in particular the non-derogable nature of the prohibition of torture and the prevention of cruel, inhuman or degrading treatment or punishment. The Committee also notes with concern that medical personnel working in detention facilities receive no specific training in how to detect signs of torture and ill-treatment (art. 10). The State party should strengthen its training programmes for all law-enforcement and army personnel on the absolute prohibition of torture and other ill-treatment, as well as those for prosecutors and judges on the State party’s obligations under the Convention. The programmes should include the inadmissibility of confessions and statements obtained as a result of torture. The State party should also ensure that all medical personnel working with detainees receive adequate training on detecting signs of torture or ill-treatment, in accordance with international standards as set out in the Istanbul Protocol (Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment). (36) The Committee notes the State party’s acceptance of the recommendation made in the course of the universal periodic review to ratify the Optional Protocol to the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment and to establish a national prevention mechanism (A/HRC/WG.6/5/L.4, para. 82)1 and encourages it to take all necessary measures to that end. (37) The Committee recommends that Chad should make declarations under articles 21 and 22 of the Convention. (38) The Committee encourages the State party to involve NGOs, United Nations experts in the field and academic experts in the review of domestic legislation, including the draft criminal code, to bring it into line with the provisions of the Convention. The State party should take the necessary steps to adopt the draft code without delay. (39) The Committee encourages the State party to continue its cooperation with MINURCAT and to seek technical cooperation from the Office of the United Nations High Commissioner for Human Rights in zones that do not fall within the mandate of MINURCAT, in order to implement the recommendations of the Committee, in particular those contained in paragraphs 27 and 35 above, and to embark on the reforms needed to consolidate the rule of law. (40) The State party should establish effective mechanisms to collect data and produce statistics on criminal justice and crime and all statistics relevant to monitoring implementation of the Convention at the national level. The State party should thus provide in its next periodic report the following data, which will facilitate the Committee’s assessment of the implementation of obligations arising from the Convention: 1 The final document will be issued under symbol number A/HRC/12/5 (http://www.ohchr.org/EN/HRBodies/UPR/ PAGES/TDSession5.aspx). 80
