Mass Shooting

A mass shooting is a violent crime in which one or more attackers use a firearm to kill or injure multiple individuals in rapid succession. There is no widely accepted specific definition, and different organizations tracking such incidents use different criteria. Mass shootings are generally characterized by the targeting (often indiscriminate) of victims in a non-combat setting, and thus the term generally excludes gang violence, shootouts and warfare. Mass shootings may be done for personal or psychological reasons, such as by individuals who are deeply disgruntled, seeking notoriety, or are intensely angry at a perceived grievance; though they have also been used as a terrorist tactic, such as when members of an ethnic or religious minority are targeted. The perpetrator of an ongoing mass shooting may be referred to as an active shooter. In the United States, the country with the most mass shootings, the Investigative Assistance for Violent Crimes Act of 2012 defines "mass killings" as three or more killings in a single incident. https://en.wikipedia.org/wiki/Mass_shooting

The United States has had the most mass shootings of any country in the world.[35][36][37] There were 103 deaths in mass shootings in 2021 (excluding the perpetrators) using the FBI's definition, and 706 deaths using the Gun Violence Archive's definition.[7] The FBI's definition refers to "active shooter incidents" defined as "one or more individuals actively engaged in killing or attempting to kill people in a populated area", while the Gun Violence Archive's definition counts incidents where at least four people (excluding the perpetrator) were shot, but not necessarily killed.
