C. Considerations of law 2. Right to life (Article 4(1)) 118. 132 In relation to the right to life, the Commission recalls: Article 4 of the Convention guarantees the right of every human being to not be deprived of his life arbitrarily, which includes the need that the State adopt substantive measures to prevent the violation of this right, as would be the case of all measures necessary to prevent arbitrary killings by its own security forces, as well as to prevent and punish the deprivation of life as a consequence of 133 criminal acts carried out by individual third parties. 119. The Inter-American Court has held that States have the right and obligation guarantee 134 their security and maintain public order, using force as necessary. In this regard, the IACHR recalls that while state agents, in the course of anti-terrorist operations may resort to the use of lethal force against suspected terrorists, and in some circumstances lethal force may be required, the power of the State is not unlimited, nor may it resort to any means to achieve its ends “regardless of the seriousness of certain actions and the culpability of the perpetrators of certain crimes.135 As the Inter-American Court of Human 126 Petitioners’ communication of February 8, 2011.
