8 b. Regarding the duty to guarantee that the protective measures are not provided by the security forces who, according to the beneficiaries, were involved in the facts denounced 17. Colombia reported that "the National Police have done positive work towards implementing the security measures." It recognized that "certain difficulties in the implementation of the measures" have arisen. However, it indicated that the National Police had taken charge of "taking […] the necessary corrective action for improving communication between the police officers and the beneficiaries." It also pointed to "that body's willingness to adopt the corrective action necessary in the event that difficulties arise in the implementation of the security measures." It insisted that "as a consequence of the comments of the beneficiaries," the Police had taken charge of making the necessary changes in order for the beneficiaries to feel comfortable with the officials in charge of their security. In this regard, the State indicated that in follow-up and coordination meetings on the measures, held in September 2009 and February of 2010, beneficiaries Mery Naranjo and María del Socorro Mosquera had expressed satisfaction with the work done by the National Police and had recognized "an improvement in the security work" provided by that body. In addition, it reported on several disciplinary investigations opened against members of the national police who allegedly committed infractions while carrying out their duties. Likewise, it indicated that the Office of the Attorney General of the Nation had asked the beneficiaries to submit the corresponding complaints "in a complete and precise manner before the disciplinary instances of the National Police" when conduct infractions are committed by the officials assigned to their protection. 18. For their part, the representatives indicated that although the beneficiaries had expressed their satisfaction with regard to the changes made during the follow-up meeting held in February of 2010, the changes that the State had made were neither sufficient nor effective for eliminating the risk faced by the victims. In this regard, they made reference to the problems that the beneficiaries have been experiencing with the police officers in charge of their security, such as "inebriation, poor behavior, and failure to man the permanent guard post," as well as “grave actions, […] crimes and […] infractions committed by police officers." In this sense, as an example they recounted that in the initial days of the month of April of 2010, a police officer assigned to the permanent post in front of the residence of Ms. Mery Naranjo "fired several times into the air solely so that the members of the gangs or ‘combos’ would respond to the shots," putting the lives and integrity of the beneficiary and her family in danger. They said that officer had behaved that way “for several days." They indicated that the beneficiary submitted several complaints to his superiors but that "only a week later" was the police officer removed from the location. They insisted that because of these situations, Ms. Mery Naranjo has had to submit several complaints to the corresponding authorities, giving rise to harassment and threats "from the police themselves." They highlighted that she has "repeatedly and with great concern" expressed in follow-up and coordination meetings with the State on these measures that "the poor performance and excesses of the police force in the permanent post put the beneficiary Mery Naranjo and her relatives at great risk." 19. The Commission commented that the State has not submitted information "regarding which State security bodies are providing protection to the beneficiaries." c.
