that threaten their lives, as well as to provide the necessary conditions of a dignified life, including food, water, adequate ventilation, an environment free from disease, and the provision of adequate healthcare (including maternal healthcare and the provision of antiretroviral drugs). The State should provide necessary information on places of detention, the identity and age of those detained, as well as the authorities responsible. (37) Where a person dies in State custody, there is a presumption of State responsibility and the burden of proof rests upon the State to prove otherwise through a prompt, impartial, thorough and transparent investigation carried out by an independent body. This heightened responsibility extends to persons detained in prisons, in other places of detention (official and otherwise), and to persons in other facilities where the State exercises heightened control over their lives. H. Responsibility for violations by non-State actors (38) The State also has an obligation to protect individuals from violations or threats at the hands of other private individuals or entities, including corporations. The State should ensure that all individuals are able to exercise their rights and freedoms, for example, by promoting tolerance, non-discrimination, and mutual respect. Moreover, the State has a responsibility for those deaths where authorities knew or ought to have known of an immediate threat and failed to take measures that might have been expected to avoid those deaths. States shall take appropriate measures to investigate cases of enforced disappearances committed by persons or groups acting without the authorisation, support or acquiescence of the State, and to bring those responsible to justice. (39) The State is responsible for killings by private individuals which are not adequately prevented, investigated or prosecuted by the authorities. These responsibilities are heightened when an observable pattern has been overlooked or ignored, such as is often the case with respect to mob-justice, gender-based violence, femicide, or harmful practices. States must take all appropriate measures effectively to respond to, prevent and eliminate such patterns or practices. 16
