CAT/C/NAM/CO/2 reports of murder of persons selling sexual services and prosecute and punish all persons found guilty of such crimes. Human trafficking 40. The Committee notes with concern that, while the State party has ratified the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, supplementing the United Nations Convention against Transnational Organized Crime, there is still no specific anti-trafficking legislation in place. The Committee is also concerned that the number of prosecutions is low, despite reports that women and children are trafficked in the territory of the State party. 41. The State party should adopt anti-trafficking legislation that enables the prosecution of offenders in line with international standards, and investigate all persons suspected of having committed human trafficking and prosecute and punish them if found guilty. Data collection 42. The Committee regrets the absence of comprehensive and disaggregated data on complaints, investigations, prosecutions and convictions in cases of torture and ill-treatment perpetrated by law enforcement and prison personnel, as well as on deaths in custody, gender-based violence and human trafficking. 43. 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 in cases of torture and ill-treatment, gender-based violence and human trafficking, as well as on means of redress, including compensation and rehabilitation provided to victims. Training 44. While taking note of the information provided by the State party on training in constitutional and human rights matters provided to the Namibian police, the national defence force, the prison service, other law enforcement personnel and medical personnel, the Committee remains concerned about the inadequate level of training on the provisions of the Convention of State officials and other relevant individuals. That is particularly the case for members of the national police force, members of the judiciary, prison staff and doctors dealing with cases of torture and ill-treatment (arts. 2, 10 and 16). 45. The State party should ensure that specialized training for officials of the national police force, members of the judiciary, including judges, prosecutors and lawyers, and medical and prison staff systematically includes modules on the provisions of the Convention, the Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (the Istanbul Protocol), the principles of preventive detention monitoring and international human rights protection standards. Such training should involve the study of specific cases and should also focus on gender-specific violence. The State party should carry out assessments on a regular basis in order to measure the effectiveness and impact of the training on the full respect for the absolute prohibition and prevention of torture. The Committee recommends that the State party establish training programmes on non-coercive investigation and inquiry techniques and strengthen procedural safeguards to ensure that the fight against torture is effective and employs techniques that respect human dignity and the presumption of innocence, as recommended in the interim report of the Special Rapporteur on torture and other cruel, inhuman or degrading treatment or punishment (see A/71/298, paras. 101-103). 9
