159 c) the Commission points out that the process of demobilizing paramilitary groups includes negotiations on benefits for their members in legal proceedings; d) the State must ensure that paramilitary presence is eradicated through State action and that those who have been displaced by violations in the instant case may, if they so wish, return to Mapiripán; e) the amounts allegedly paid are not in connection with the same matter being heard by the Court, nor have they been set in accordance with the Court’s criteria on reparations. Furthermore, the subject matter of this proceeding, regarding the international responsibility of the State for violating its obligations under the American Convention, is different from the subject matter of the administrative-law proceeding; f) the Commission recognizes the value of the State’s expression of regret for the loss of human lives and of its apology, as this is an initial step in the process of historical remembrance of the fatal victims and of satisfactions owed to their next of kin and to the survivors; g) the Court must establish the general criteria for individual identification and establishment of the beneficiaries of the reparations; h) the measures of satisfaction applicable in the instant case are acknowledgment of responsibility, apology, Publicity, and commemoration. As other forms of reparation the State must: i. conduct a serious, complete, and effective investigation to establish the liability of the masterminds and direct perpetrators of the massacre, as well as that of individuals whose acquiescence made it possible for the massacre to take place. This investigation must lead to criminal punishment for those responsible; ii. effectively complete the investigation underway, in accordance with the international obligations that it has freely undertaken; iii. take such steps as may be necessary to identify the victims so that their next of kin can complete the grieving process due to their disappearance and thus enable, to some extent, reparation of the damage caused; iv. execute the arrest warrants already issued by court authorities, including that of paramilitary leader Carlos Castaño; v. hold a public act of acknowledgment of international responsibility and explanation of its scope and consequences by a high official of the State in the community of Mapiripán. It must also publish the operative part of the judgment and the chapter on proven facts in the official gazette Diario Oficial and in a nationally distributed daily; vi. carry out, in consultation with the next of kin, a symbolic acknowledgment in remembrance of the victims of the massacre;
