What term describes an incident involving multiple victims of gun violence?

The term that best describes an incident involving multiple victims of gun violence is "mass shooting." This term is commonly used to refer to events where a shooter actively engages in gunfire that results in several injuries or fatalities, typically occurring in public spaces such as schools, malls, or concerts. The defining feature of a mass shooting is the number of people affected, emphasizing the scale of the violence rather than the context in which it occurs.

The other options refer to different circumstances or types of violence. An active shooter situation describes a scenario where an individual is actively engaged in killing or attempting to kill people in a confined and populated area, but it does not necessarily specify the number of victims. A hostage crisis involves holding individuals against their will, which may or may not involve firearm violence but is distinct from a mass shooting. Domestic terrorism is defined as violent, criminal acts committed by individuals or groups to intimidate or coerce a population, typically related to political or ideological goals, and can encompass mass shootings but is broader in scope. Thus, "mass shooting" specifically aligns with the scenario of multiple gun violence victims.
