Artificial intelligence is moving rapidly from decision support to decision influence in crowd management and event safety, yet responsibility has not shifted alongside it. In this session, we'll will explore how AI-enabled systems shape human judgement in safety-critical environments. The discussion will consider where risk can emerge through acts of commission and omission, and how those risks are shaped by the interaction between technology, people, and existing regulatory frameworks. The session will focus on accountability rather than technology alone, asking a central question: who ultimately carries liability when technology, people, and regulatory frameworks collide?
