several different types including public shootings, bar/club incidents, family annihilations, drive-by, workplace and those which defy description but with the established foundation definition being that they have a minimum of four victims shot, either injured or killed, not including any shooter who may also have been killed or injured in the incident.
Why are GVA Mass Shooting numbers higher than some other sources?
GVA uses a purely statistical threshold to define mass shooting based ONLY on the numeric value of 4 or more shot or killed, not including the shooter. GVA does not parse the definition to remove any subcategory of shooting. To that end we don’t exclude, set apart, caveat, or differentiate victims based upon the circumstances in which they were shot.
GVA believes that equal importance is given to the counting of those injured as well as killed in a mass shooting incident.
The FBI does not define Mass Shooting in any form. They do define Mass Murder but that includes all forms of weapon, not just guns.
In that, the criteria are simple…if four or more people are shot or killed in a single incident, not including the shooter, that incident is categorized as a mass shooting based purely on that numerical threshold.
