31 motivation of the agent who has violated the rights recognized by the Convention is irrelevant -the violation can be established even if the identity of the individual perpetrator is unknown. What is decisive is whether a violation of the rights recognized by the Convention has occurred with the support or the acquiescence of the government, or whether the State has allowed the act to take place without taking measures to prevent it or to punish those responsible. Thus, the Court's task is to determine whether the violation is the result of a State's failure to fulfill its duty to respect and guarantee those rights, as required by Article 1 (1) of the Convention. 174. The State has a legal duty to take reasonable steps to prevent human rights violations and to use the means at its disposal to carry out a serious investigation of violations committed within its jurisdiction, to identify those responsible, to impose the appropriate punishment and to ensure the victim adequate compensation. 175. This duty to prevent includes all those means of a legal, political, administrative and cultural nature that promote the protection of human rights and ensure that any violations are considered and treated as illegal acts, which, as such, may lead to the punishment of those responsible and the obligation to indemnify the victims for damages. It is not possible to make a detailed list of all such measures, since they vary with the law and the conditions of each State Party. Of course, while the State is obligated to prevent human rights abuses, the existence of a particular violation does not, in itself, prove the failure to take preventive measures. On the other hand, subjecting a person to official, repressive bodies that practice torture and assassination with impunity is itself a breach of the duty to prevent violations of the rights to life and physical integrity of the person, even if that particular person is not tortured or assassinated, or if those facts cannot be proven in a concrete case. 176. The State is obligated to investigate every situation involving a violation of the rights protected by the Convention. If the State apparatus acts in such a way that the violation goes unpunished and the victim's full enjoyment of such rights is not restored as soon as possible, the State has failed to comply with its duty to ensure the free and full exercise of those rights to the persons within its jurisdiction. The same is true when the State allows private persons or groups to act freely and with impunity to the detriment of the rights recognized by the Convention. 177. In certain circumstances, it may be difficult to investigate acts that violate an individual's rights. The duty to investigate, like the duty to prevent, is not breached merely because the investigation does not produce a satisfactory result. Nevertheless, it must be undertaken in a serious manner and not as a mere formality preordained to be ineffective. An investigation must have an objective and be assumed by the State as its own legal duty, not as a step taken by private interests that depends upon the initiative of the victim or his family or upon their offer of proof, without an effective search for the truth by the government. This is true regardless of what agent is eventually found responsible for the violation. Where the acts of private parties that violate the Convention are not seriously investigated, those parties are aided in a sense by the government, thereby making the State responsible on the international plane. 178. In the instant case, the evidence shows a complete inability of the procedures of the State of Honduras, which were theoretically adequate, to carry out an investigation into the disappearance of Manfredo Velásquez, and of the fulfillment of its duties to pay compensation and punish those responsible, as set out in Article 1 (1) of the Convention. 179 As the Court has verified above, the failure of the judicial system to act upon the writs brought before various tribunals in the instant case has been proven. Not one writ of habeas corpus was processed. No judge has access to the places where Manfredo Velásquez might have been detained. The criminal complaint was dismissed. 180. Nor did the organs of the Executive Branch carry out a serious investigation to establish the fate of Manfredo Velásquez. There was no investigation of public allegations of a practice of
