active shooter
Ongoing firearm threat
An active shooter is a person currently engaged in killing or attempting to kill people in a populated area, typically with firearms.
The term emerged from law enforcement and emergency response contexts: The school went into lockdown after reports of an active shooter.
It implies an ongoing threat requiring immediate action, distinguishing current attacks from past incidents or general gun violence.
