Demonstrably false.
“The actual data show that some of these kind of heroic, Hollywood moments of armed citizens taking out active shooters are just extraordinarily rare,” Mr. Lankford said.
In fact, having more than one armed person at the scene who is not a member of law enforcement can create confusion and carry dire risks. An armed bystander who shot and killed an attacker in 2021 in Arvada, Colo., was himself shot and killed by the police, who mistook him for the gunman.
It was twice as common for bystanders to physically subdue the attackers, often by tackling or striking them. At Seattle Pacific University in 2014, a student security guard pepper sprayed and tackled a gunman who was reloading his weapon during an attack that killed one and injured three others. The guard took the attacker’s gun away and held the attacker until law enforcement arrived. When a gunman entered a classroom at the University of North Carolina at Charlotte in 2019, a student tackled him. The student was shot and killed, but the police chief said the attack would have had a far worse death toll had the student not intervened.
