This chapter delves into the wave of protests across Latin America in 2019, sparked by deep-rooted inequalities and public discontent with governance in countries like Chile, Colombia, Bolivia, and Ecuador. It highlights how state responses, often marked by severe repression, led to grave human rights violations. The chapter investigates the critical yet complex role of technology in these events, examining its dual capacity as a tool for both state repression and as a means for documenting abuses and supporting truth-seeking efforts. Technologies such as facial recognition, drones, and social media monitoring enhanced state surveillance but also provided critical evidence for accountability. The chapter concludes by discussing the implications of corporate complicity in supplying these technologies, underscoring the urgent need for regulatory frameworks that safeguard human rights and prevent the misuse of technology in suppressing dissent.
