Good practice Targeted visits by civil society organisations to examine the situation of LGBTI detainees In Guatemala, the “National Network on Sexual Diversity and HIV” (REDNADS) initiated a review of the needs of LGBTI persons deprived of their liberty. The Network’s members visited 7 prisons between December 2014 and January 2015, with the purpose of examining issues of visibility, conditions of detention, discrimination, ill-treatment, free development of one’s personality, intimate visits, sensitisations of prison officials, and institutional management. The review process included interviews with 54 LGBTI detainees, as well as with prison management, multidisciplinary teams among prison staff, and 15 key LGBTI stakeholders from the community. Based on the findings, REDNADS subsequently issued a report with standards and guidelines for the treatment of LGBTI detainees jointly with the Department of Vulnerable Groups of the Penitentiary Administration. The process included several roundtables with LGBTI detainees, as well as with civil society organisations and penitentiary staff. A pilot training for the Penitentiary training school was also included in the process.
