Miami Beach's Spring Break Crisis: Violence and Emergency Measures.

Miami Beach is struggling with spring break violence, including two fatal shootings and unruly crowds, despite a massive police presence and activities designed to give people alternatives to drinking alcohol and roaming the streets. The city imposed an overnight curfew that ended Monday morning but decided at a City Commission meeting not to enact a second curfew next weekend, when the Ultra Music Festival will draw thousands of people to South Beach. The violence and street chaos continues at night.
