A mass shooting is an incident involving multiple victims of firearms-related violence. The United States' Congressional Research Service acknowledges that there is not a broadly accepted definition, and defines a "public mass shooting" as one in which four or more people selected indiscriminately, not including the perpetrator, are killed, echoing the FBI definition of the term "mass murder". Another unofficial definition of a mass shooting is an event involving the shooting (not necessarily resulting in death) of four or more people with no cooling-off period. Related terms include school shooting and massacre. The lack of a single definition can lead to alarmism in the news media, with some reports conflating categories of crimes.
A mass shooting may be committed by individuals or organizations in public or non-public places. Terrorist groups in recent times have used the tactic of mass shootings to fulfill their political aims. Individuals who commit mass shootings may fall into any of a number of categories, including killers of family, of coworkers, of students, and of random strangers. Individuals' motives for shooting vary.
Responses to mass shootings take a variety of forms, depending on the context: number of casualties, the country and political climate, among other factors. Countries such as Australia and the United Kingdom have changed their gun laws in the wake of mass shootings. The news media and other types of media cover mass shootings extensively, and the effect of that coverage has been examined. Unlike these countries, the United States constitution currently prohibits such laws restricting firearm ownership.
