93 238. As for non-custodial precautionary measures, the Commission considers that States should first adequately regulate their use and enforcement; ensure the allocation of the financial resources necessary to make them operational and available to the largest number of people possible; implement training programs for the officials involved in the different stages of their use; and establish mechanisms for supervising their compliance and results. It is also important to produce statistics and reliable and systematic information on the results obtained with the use of those measures in order to identify possible obstacles in their application and implementation, as well as to adopt the pertinent measures to ensure their increased and more efficient use. 239. According to Ecuador’s General Public Defender, it is necessary to operationalize alternatives to pretrial detention, since the absence of monitoring structures for their real effectiveness leads to their political and judicial “demonization”, mistrust among prosecutors and victims, the “codification” of judicial debate that reduces the possibilities of trials being conducted while the accused is free, and the 338 judicial disuse of non-custodial precautionary measures. 240. The Commission considers it is essential that States set appropriate mechanisms for assessing procedural risks and for supervising the application of noncustodial precautionary measures, such as those known as pretrial evaluation and supervision services or offices for alternative measures. In general, such agencies serve two functions: first, they gather and verify information from different sources about the accused, which they present to the court as elements to be taken into consideration in assessing the applicability of and need for a given precautionary measure; and, second, they conduct oversight of compliance with non-custodial precautionary measures. The use of this mechanism fosters confidence, both within the judiciary, whose officers feel they have greater support when ordering measures, and within society, which receives the message that pretrial liberty is not a synonym for impunity. In addition, studies have documented the economic benefits to the public administration of establishing this kind 339 of pretrial services. 241. To summarize, the Commission considers that promoting greater use of precautionary measures other than pretrial detention is not only consistent with the principle of the exceptionality of pretrial detention and the right to presumption of innocence, but also that alternative measures tend by their very nature to be sustainable and effective as part of a comprehensive strategy to prison overcrowding.
