Law enforcement and security 30. According to the explanations offered by the delegation regarding the armed forces’ involvement in security operations to combat organized crime, for the time being, the State party does not consider it possible to relieve the army of its current duties in the field of security. The Committee expresses its concern in this regard, as well as about reports alleging grave human rights violations, including torture, committed by military officers during operations of this kind. The Committee takes note of the recent establishment of the National Guard – a new civilian law enforcement agency that will replace the Federal Police – but is concerned that a military officer who is about to retire has been appointed as the new agency’s chief of operations. It is also concerned about the lack of clarity regarding the rules applicable to the use of force and the identification of members of the security forces and their vehicles (arts. 2, 12, 13 and 16). 31. The State party should: (a) Ensure that all complaints of excessive use of force, especially lethal force, by law enforcement and military personnel are promptly and impartially investigated, that the suspected perpetrators are prosecuted and, if found guilty, are punished in a manner commensurate with the seriousness of their actions, and that the victims or their families receive full redress; (b) Publish the numbers of persons killed, injured or detained during law enforcement operations; (c) Ensure that law and order is maintained, to the greatest extent possible, by civilian rather than military authorities. It should also guarantee that the National Guard is under civilian command in order to preserve its independence; (d) Adopt the national legislation on the use of force envisaged under article 73 (XXIII) of the Constitution, in accordance with the content of the Basic Principles on the Use of Force and Firearms by Law Enforcement Officials; (e) Take the measures necessary to ensure that members of the security forces can be properly identified at all times during the exercise of their duties.
