This document from Human Rights Watch investigates alleged human rights violations committed by Venezuelan security forces in response to protests since February 2014. It documents 45 cases of serious abuses, including unlawful killings, torture, arbitrary arrest and detention, and violations of due process rights. The abuses appeared to target both protesters and those documenting the security response, and occurred across multiple states. Prosecutors and judges failed to properly investigate and enable accountability. While some protesters have used violence, evidence suggests many victims of security force abuses were nonviolent or not engaged in criminal activity at the time.
