CRC/C/GTM/CO/3-4 (b) Facilitate strengthening of family ties of children in street situations; and their reunification with their families, when appropriate and in the best interests of the child; (c) Extend the assistance measures to support children in order to facilitate their full reinsertion into school; (d) Pay greater attention to girls in street situations and their particular vulnerabilities; (e) Prioritize the data collection system on children in street situations and utilize this information to develop sustainable programmes and provision of basic services for these children, with their participation. Youth gangs (“Maras”) 92. The Committee is concerned that the climate of fear, insecurity, threat and violence linked to these gangs impedes children from enjoying their childhood and adolescence. The Committee also notes with concern that not enough attention is being paid by the State party to the root causes of this phenomenon, which has so far been tackled mostly as a criminal justice problem and with insufficient socio-economic measures. 93. The Committee recommends that the State party develop a comprehensive public policy to deal with this problem, addressing the social factors and root causes of juvenile violence, such as social exclusion, lack of opportunities, culture of violence, migration flows, inter alia. The Committee also recommends that the State party invest in prevention activities, with an emphasis on the school, the family and social inclusion measures. Sexual exploitation and trafficking 94. While welcoming the 2009 Act on Sexual Violence, Exploitation and Trafficking in Persons, which reforms the Penal Code inter alia in relation to child prostitution, child pornography and trafficking, the Committee remains concerned that there have been no convictions for sexual exploitation since the adoption of the Law. The Committee is also concerned at the tolerance of trafficking, which has led to underreporting and impunity. The Committee is further concerned at the lack of specialized or appropriate care for victims by the competent authorities and government support to NGOs who work on these issues. 95. The Committee recommends that the State party: (a) Properly implement the Act on Sexual Violence, Exploitation and Trafficking, inter alia by investigating, prosecuting and punishing the perpetrators; (b) Allocate the necessary budgetary resources to operationalize the public policy against trafficking in persons, including the creation of specialized shelters for victims of trafficking and care programmes; and (c) Publish and widely disseminate the report on the investigation carried out by the International Commission against Impunity in Guatemala (CICIG) regarding the impact of organized crime on children, encompassing trafficking, kidnapping and killing, including of girls, and implement all CICIG’s recommendations in this regard. Helplines 96. 16 The Committee is concerned that the State party does not have a child helpline.
