169 g) Monument 315. The State must build an appropriate and dignified monument in remembrance of the facts in the Mapiripán Massacre, as a measure to prevent such grave events happening in the future. Said monument must be placed in an appropriate public space in Mapiripán, within a year of notification of the instant Judgment. h) Human rights education 316. Bearing in mind that the Mapiripán Massacre was committed by paramilitary who acted with the collaboration, tolerance and acquiescence of State agents, breaching the imperative provisions of International Law, the State must take steps to train the members of its armed forces and of its security agencies regarding the principles and provisions for protection of human rights and of international humanitarian law and on the limits to which it must be subject. Therefore, the State must implement, within a reasonable time, permanent education programs on human rights and international humanitarian law within the Colombian Armed Forces, at all hierarchical levels. 317. Said programs must specifically refer to the instant Judgment, to international human rights instruments and to international humanitarian law. In this regard, the Constitutional Court of Colombia has pointed out, with regard to the obligations derived from Protocol II to disseminate international humanitarian law, that knowledge of said law “is an essential requirement for it to be respected by the parties that oppose each other. Therefore […] all humanitarian law agreements attach a special importance to the task of disseminating humanitarian rules, not only among the opposing parties but also among the civilian population, for the latter to be aware of its rights in the context of the armed conflict. Furthermore, […] the State must disseminate them [and] and they must be studied in educational institutions […] Specifically, [it is] indispensable for the members of the security forces to be familiar with humanitarian rules, not only because they are natural addressees of said regulations but also because the Constitution itself states that they must receive human rights education […].”294 i) Publication of the pertinent parts of the instant Judgment 318. The Court deems that, as a measure satisfaction, the State must publish once, within six months of notification of the instant Judgment, in the official gazette Diario Oficial and in another national daily, the section of this Judgment on Proven Facts, without the respective footnotes, paragraphs 101 and 123 of the section on International Responsibility of the State, as well as the operative section of this Judgment.
