Compensation and rehabilitation (32) The Committee expresses its concern about the lack of compensation for victims of torture and other cruel, inhuman or degrading treatment, and at the limited measures for the rehabilitation of victims of torture, ill-treatment, trafficking and domestic and sexual violence (art. 14). The State party should ensure that adequate compensation is provided to victims of torture and ill-treatment and that appropriate rehabilitation programmes are provided to all victims of torture, ill-treatment, trafficking and domestic and other sexual violence, including medical and psychological assistance. Legal aid (33) The Committee expresses its concern about the difficulties persons, including members of vulnerable groups, experience in their efforts to exercise the right to make complaints and to obtain redress and fair and adequate compensation as victims of acts of torture (arts. 13 and 14). The State party should take measures to provide an effective free legal aid system, in particular for persons at risk or belonging to groups made vulnerable. It should ensure that the system is adequately resourced to guarantee that all victims of acts of torture and ill-treatment can exercise their rights under the Convention. Human rights training (34) While acknowledging a variety of programmes and manuals prepared by the State party, the Committee regrets the insufficient training with regard to the provisions of the Convention for law enforcement, military and security personnel, as well as for judges and prosecutors. The Committee also notes with concern the lack of specific training of medical personnel in detention facilities to detect signs of torture and ill-treatment (arts. 10 and 11). The State party should reinforce its training programmes for all law enforcement and military personnel on the absolute prohibition of torture, as well as for all members of the judiciary and prosecutors on the specific obligations under the Convention. The State party should also ensure adequate training for all medical personnel involved with detainees, to detect signs of torture and ill-treatment in accordance with international standards, such as those outlined in the Istanbul Protocol. Data collection (35) The Committee regrets the absence of comprehensive and disaggregated data on complaints, investigations, prosecutions and convictions of cases of torture and ill-treatment by law enforcement and military personnel, as well as on trafficking, enforced disappearances, internally displaced persons, violence against children, ill-treatment of migrant workers, violence against minorities and domestic and sexual violence. The State party should compile statistical data relevant to the monitoring of the implementation of the Convention at the national level, including data on complaints, investigations, prosecutions and convictions of cases of torture and ill-treatment, trafficking, enforced disappearances, internally displaced persons, violence against children, ill-treatment of migrant workers, violence against minorities and domestic and sexual violence, especially in military conflict areas, as well as on compensation and rehabilitation provided to the victims. (36) The Committee encourages the State party to implement the recommendations contained in the report of the Special Rapporteur on torture on his visit in November 2007 (A/HRC/7/3/Add.7), the report of the Special Rapporteur on the human rights of migrants on his visit in December 2006 (A/HRC/4/24/Add.3), the report of the Special Representative of the Secretary-General on the situation of human rights defenders on her visit in June 2007 (A/HRC/7/28/Add.2) and the report of the Special Rapporteur on the independence of judges and lawyers on his visit in July 2002 (E/CN.4/2003/65/Add.2). 71
