department (abbreviated as UMPD) operates 24/7 and is accessible by dialing 911 (from a university owned landline) or (413) 545-3111 for emergencies, or (413) 577-8477 for non-emergencies and to leave confidential tips. Calling 911 from a cell phone will typically redirect users to the state-operated dispatch rather than UMPD. To ensure commuter safety the UMass Police Department employs a safety and escort service that offers a safe escort across campus every night. The UMPD has several specialized units that make up the department including bicycle, K-9, motorcycle, and mounted horseback units as well as foot and vehicle patrol. The Police Cadet program has been a part of the UMPD since 2000. It is viewed as a successful program by the department and the UMass community since the cadets are an important part of the police department. Their presence can be seen mostly in the residential areas, where the cadets work very closely with police officers and Residence Hall Security. Cadets take part in a two-week "boot-camp"-style training in preparation for the position. The training consists of police techniques, performing foot patrols, parking enforcement, prisoner watch, and other functions to free officers. The cadets operate as the eyes and the ears of the police department as they can see and hear what the officers cannot, preventing problems and their escalation. In the past, there had been several occurrences of large non-school sponsored gatherings labeled as riots, where UMass officials had been called in. After the Red Sox won the World Series in 2013, an estimated 3,000 students gathered in the outdoor space around South West Residence Hall. In response to the situation, UMass police officials were called in. Police accounts state that some students participated in disruptive behavior: knocking over trash bins and climbing trees. Rubber bullets and tear gas were dispersed into the crowds. According to WGGB, 14 people were arrested for failing to disperse and 1 for disorderly conduct. Whether or not the use of police force was necessary is still a controversial topic among students, the administration, and UMass and Amherst Police Department. According to MassLive, other riots include one in 2007 after the Boston Red Sox lost in the 2008 playoffs, another when they lost in the World Series run in 2006, one after UMass' football team lost in the Division I-AA football championship in 2006, one after the Red Sox World Series victory in 2004, another
