Definitions of Mass Violence Crimes
There is no universal definition of mass violence crimes, mass murders or mass killings. Many different definitions are used by researchers, criminal justice experts, and public policy bodies. Some definitions focus solely on the number of deaths, but others count crimes in which there are few deaths but many injuries. Some definitions focus on the method used to kill and injure (e.g. firearms only) and others include crimes committed with any weapon. Some definitions focus on the perceived motive of the perpetrator (e.g. hate, terrorism, or a desire to kill strangers) or who was attacked (and do not count mass casualty crimes as mass violence if the perpetrator’s motive was to kill family members or rival gang members). Some definitions are designed to establish eligibility requirements to receive federal assistance after mass violence crimes.
There are three different definitions provided by the Federal government:
U.S. CONGRESS -- Federal Bureau of Investigation -- OFFICE FOR VICTIMS OF CRIMES
The U.S. Congress has defined mass violence in legislation.
“The term ‘mass killings’ means three or more killings in a single incident” that occur in a ‘public place’.”
(The term) “mass shooting” is defined as a multiple homicide incident in which four or more victims are murdered with firearms, within one event, and in one or more locations in close proximity. Similarly, a “mass public shooting” is defined to mean a multiple homicide incident in which four or more victims are murdered with firearms, within one event, in at least one or more public locations, such as, a workplace, school, restaurant, house of worship, neighborhood, or other public setting.
The lack of a consistent definition for mass violence can be confusing, and developing a more uniform definition would be helpful. However, the most important thing to remember irrespective of the definition used is that each mass violence incident leaves behind numerous victims and survivors who need assistance and support.
