The Committee recommends that the State party should: (a) Strengthen its measures to ensure prompt, impartial and effective investigations into all allegations of torture and ill-treatment committed by law enforcement officials. In particular, such investigations should not be undertaken by or under the authority of the police, but by an independent body. In connection with prima facie cases of torture and ill-treatment, the alleged suspect should as a rule be subject to suspension or reassignment during the process of investigation, especially if there is a risk that he or she might impede the investigation; (b) Try the perpetrators and impose appropriate sentences on those convicted in order to eliminate impunity for law enforcement personnel who are responsible for violations prohibited by the Convention; and (c) Review its rules and provisions on the statute of limitations and bring them fully in line with its obligations under the Convention so that acts of torture as well as attempts to commit torture and acts by any person which constitute complicity or participation in torture, can be investigated, prosecuted and punished without time limitations. Compensation and rehabilitation (18) While noting information on treatment and social rehabilitation services provided to, inter alia, detainees and child victims of violence, the Committee regrets the lack of a specific programme to safeguard the rights of victims of torture and ill-treatment. The Committee also regrets the lack of available information regarding the number of victims of torture and ill-treatment who may have received compensation and the amounts awarded in such cases as well as the lack of information about other forms of assistance, including medical or psychosocial rehabilitation, provided to these victims (art. 14). The State party should strengthen its efforts in respect of compensation, redress and rehabilitation in order to provide victims with redress and fair and adequate compensation, including the means for as full rehabilitation as possible. The State party should develop a specific programme of assistance in respect of victims of torture and ill-treatment. Furthermore, the State party should provide in its next periodic report information about any reparation programmes, including treatment of trauma and other forms of rehabilitation provided to victims of torture and ill-treatment, as well as the allocation of adequate resources to ensure the effective functioning of such programmes. Rights of vulnerable groups and discrimination (19) While noting a number of measures adopted by the State party, including the recent amendment in article 48 of the Criminal Law to include racial motivation as an aggravating factor for criminal liability, the Committee expresses its concern at report of acts of violence against and discrimination of vulnerable groups, including the Roma and the lesbian, gay, bisexual and transgender (LGBT) community. The Committee is concerned at reports that the number of allegedly racially motivated crimes has recently increased and that the number of reported hate crimes is underestimated due to the lack of an effective hate crime recording and monitoring system. Furthermore, while the Committee takes note of the efforts made by the State party in recent years in the process of naturalisation, it remains concerned at the continued existence of the status of non-citizens and stateless persons, affecting a large group in Latvian society (art. 16). The State party should intensify its efforts to combat discrimination against and ill-treatment of vulnerable groups, in particular the Roma and the LGBT community, including through the strict application of relevant legislation and regulations providing for sanctions. The State party should ensure prompt, impartial and thorough investigations into all such motivated acts and prosecute and punish perpetrators with appropriate penalties which take into account the grave nature of their acts and ensure adequate training and instructions for law enforcement bodies and sensitization of the judiciary. The State party is encouraged to adopt the draft National Programme to Facilitate Tolerance and to provide detailed information in its next periodic report on the effective measures adopted to prevent and combat such acts. The State party should simplify and facilitate the naturalization process and integration of non-citizens and stateless persons. 24
