The Gun Violence Archive applied its mass shooting designation to six incidents in early September 2026 after each left at least four people wounded or dead by gunfire. None of those incidents involved a household dispute or an untargeted public attack. All six instead arose from gang activity or existing personal disputes that participants resolved with firearms.

The archive groups such events under a single gun violence heading regardless of motive. Separate classification by the nature of each confrontation would allow attention to focus on the underlying disputes.
