This post is part of the series “Unblinking Eyes: The State of Communications Surveillance in Latin America,” a collaborative project conducted with digital rights partners in Latin America, which documents and analyzes surveillance laws and practices in twelve countries: Argentina, Brazil, Chile, Colombia, El Salvador, Guatemala, Honduras, Peru, Mexico, Nicaragua, Paraguay, and Uruguay. In addition to the individual country reports, EFF produced a comparative legal analysis of the surveillance laws in those twelve countries, as well as a regional legal analysis of the 13 Necessary and Proportionate Principles written with Derechos Digitales, and an interactive map that summarizes our findings.
