60 in the field of operations to avoid excess. And, the State must ensure that, if it is necessary to resort to physical means to face public disturbances, members of the armed forces and security agencies will use only those strictly required to control such situations in a rational and proportional manner, respecting the right to life and to humane treatment. 149. Likewise, the Court deems it appropriate that the State frame and implement a training program on human rights and international standards applied to inmates addressed to police agents and penitentiary officials. f) Public acknowledgment of liability 150. The Court thinks highly of the public acknowledgment of liability made by Venezuela during the hearing held in the instant case (supra para. 42). However, taking into account that not all next of kin were present at said hearing, and that the public acknowledgment of liability is a guarantee of non repetition that should be known by the whole Venezuelan society, the Court orders the State to publicly acknowledge its international liability and ask public forgiveness to the victims´ next of kin declared in the instant Judgment. Said acknowledgment must be made in the presence of the victims´ next of kin and the highest-ranked authorities of the State within the term of six months as from the date of service of the instant Judgment. g) Judgment publication 151. As ordered in previous cases and as a measure of satisfaction,186 the State must publish at least once in the Official Gazette and in another national daily newspaper the chapter on the facts established in the instant Judgment, without its footnotes, as well as the operative paragraphs herein. Said publications must be made within six months as from the date of service of the instant Judgment. E) COSTS AND EXPENSES 152. Costs and expenses are contemplated within the concept of reparations as enshrined in Article 63(1) of the American Convention, since the victims´ efforts to obtain justice in the domestic as well as international levels lead to expenses that must be compensated when the State’s international liability has been determined in a conviction judgment. With regard to their reimbursement, the Court must prudently assess their extent, which involve the expenses incurred when acting before the authorities with domestic jurisdiction as well as those incurred in the course of proceedings before the Inter-American System, taking into account the particular circumstances of the specific case and the nature of international jurisdiction in the protection of human rights. Said assessment might be made on equitable grounds and taking into account the expenses declared by the parties, provided the amounts are reasonable.187 153. In the instant case, the Court notes that many of the victims´ next of kin have not been identified. Therefore, it is not possible to award a compensation for 186 Cf..
