Europol’s 17th Data Protection Experts Network conference examined how law enforcement can use emerging technologies while protecting privacy, fundamental rights and the rule of law. The two-day event was held in Lisbon, Portugal, on Sept. 22 and 23, under the theme “Do Not Cross: Protecting Citizens, Preserving Rights.” More than 170 participants attended, including law enforcement officials, data protection officers, national data protection authorities and academics. The conference was organized by Europol’s Data Protection Experts Network in cooperation with the Academy of European Law and co-hosted by Portugal’s Sistema de Segurança Interna and Polícia Judiciária. Discussions focused on cloud infrastructure, cybersecurity, artificial intelligence and the handling of digital evidence. Participants also examined online violent nihilistic networks, cybersecurity resilience during wartime and the challenges faced by Ukrainian institutions amid Russia’s war against Ukraine. The conference addressed the protection of witnesses and other individuals whose safety may depend on how sensitive information is processed. It also considered the role of data protection officers in balancing operational demands with necessity, proportionality, security and respect for fundamental rights. Europol said continued cooperation among law enforcement professionals, policymakers and legal experts will be essential as technology reshapes criminal investigations.
