Large celebratory events in tourist locations can pose significant safety and security challenges. Dr. Madensen will explain the conditions that make violence and disorder more likely to occur at such events. She also will describe the tactics used to manage crowds and secure the Las Vegas Strip on New Year’s Eve. This case study will illustrate how crowd dynamics can be controlled using a systematic and structured approach to eliminating environmental risk factors.
