Training and education (22) The Committee regrets the insufficient training regarding the provisions of the Convention for law enforcement personnel, including penitentiary and border control staff, judges, prosecutors and the personnel of the armed forces. The Committee also notes with concern the lack of specific training for medical personnel acting in detention facilities in the detection of signs of torture and ill-treatment. The State party should reinforce its training programmes on the absolute prohibition of torture for all law enforcement and military personnel, as well as for all members of the judiciary and prosecutors on the State party’s obligations under the Convention. The State party should also ensure adequate training for all medical personnel involved with detainees, in the detection of signs of torture and ill-treatment in accordance with international standards, as outlined in the Istanbul Protocol. Legal aid (23) The Committee expresses its concern about the difficulties persons or groups experience in their efforts to exercise the right to complain, and to obtain redress and fair and adequate compensation as victims of acts of torture. The State party should provide an effective free legal aid system for persons at risk or belonging to groups made vulnerable. It should provide this system with adequate resources for ensuring that all victims of acts of torture may exercise their rights under the Convention. Compensation and rehabilitation (24) The Committee also expresses its concern at the lack of compensation for victims of torture and other cruel, inhuman or degrading treatment, as well at the absence of appropriate measures for rehabilitation of victims of torture, ill-treatment, trafficking, domestic and other sexual violence. The State party should ensure that adequate compensation is provided to victims of torture and ill-treatment and that appropriate rehabilitation programmes are also provided to all victims of torture, ill-treatment, trafficking, domestic and other sexual violence, including medical and psychological assistance. Conditions of detention (25) The Committee is concerned at the poor conditions of detention, such as overcrowding, and at the prevalence of HIV/AIDS and tuberculosis amongst detainees. The detention conditions of pretrial detainees in police custody are inappropriate for long periods and place detainees in a situation of great vulnerability. The Committee also expresses its concern at the absence of alternative measures to pretrial detention. The State party should adopt effective measures to improve conditions in all detention facilities, reduce the current overcrowding and meet the needs of all those deprived of their liberty, in particular regarding health care, in conformity with international standards. Data collection (26) 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 penitentiary personnel and in the armed forces, as well as on trafficking and domestic and sexual violence. The State party should establish an effective system to compile statistical data relevant to monitoring the implementation of the Convention at the national level, including complaints, investigations, prosecutions and convictions of cases of torture and ill-treatment, trafficking, and domestic, sexual and ethnically motivated violence and discrimination, as well as on compensation and rehabilitation provided to the victims. 85
