On May 14, 2015, the Office of the Special Rapporteur for Freedom of Expression of the Inter-American Commission on Human Rights called on the U.S. to reform the National Security Agency’s (NSA) bulk metadata collection program.  The Special Rapporteur noted that “legislation on the collection of intelligence and national security information has remained inadequate to advancement in technologies, allowing for an indiscriminate and unprecedented access to information related to the communications between individuals that can have a chilling effect on free expression and the search for and distribution of information.”  The Special Rapporteur called on the U.S. “to take this opportunity to establish reforms to ensure that the surveillance of communications is clearly authorized by law and that the law establishes robust limits that narrow the nature, scope and duration of these types of measures, and the grounds for ordering them.”
