18 Inches Changes the Conversation: Why Active Shooter Training Must Go Beyond Run, Hide, Fight

There is a number that should make anyone involved in violence prevention and emergency preparedness stop and think: 18 inches.

Former FBI Special Agent and Hostage Rescue Team member Greg Shaffer has stated that the average distance at which victims in mass shootings are shot is approximately 18 inches. That figure should be treated as Shaffer's estimate rather than a universally established statistic, but the underlying concept raises an important issue about active shooter preparedness: What happens when the threat is already within physical contact distance?

At 18 inches, you cannot simply outrun the threat. You may not be able to hide. There may be no locked door, barrier, or escape route between you and the attacker. You may be trapped against a wall, inside a confined space, between furniture, or among other people. When distance disappears, your available options can disappear with it.

Run, Hide, Fight Is a Framework, Not a Skill

Run, Hide, Fight has become one of the most recognized active shooter response models in the United States. Other systems, including ALICE and various lockdown, evacuation, sheltering, and emergency response models, use different terminology and priorities. These frameworks serve an important purpose. They give people a mental structure for making decisions during an extraordinarily chaotic event.

The problem occurs when the acronym becomes the training.

People are told to "run," "hide," or "fight," but knowing what to do is not the same as knowing how to do it. The physical component is particularly important because it may become necessary when other options are no longer available. Yet physical response is often the part of active threat preparedness that receives the least practical training.

Consider CPR. Imagine telling employees, "If someone's heart stops, perform CPR. Push hard and try to save their life," and then never teaching them how to perform CPR or allowing them to practice. We would not consider that adequate training. The instruction tells someone what to do. Training develops the ability to actually do it.

The same principle applies to physical resistance during an active threat.

When the Threat Is Already on Top of You

There is nothing wrong with telling people to escape whenever a safe opportunity exists. Distance, time, movement, shelter, communication, and evacuation remain critical components of an effective response. The issue is what happens when those options are no longer available.

A person who identifies an armed threat from across a parking lot may have multiple options. A person who suddenly finds an attacker within arm's reach has considerably fewer.

That difference matters.

"Fight as a last resort," "fight for your life," and "don't fight fair" may communicate urgency, but they are not physical skills. They do not teach someone how to function while experiencing a powerful survival response. They do not provide experience with resistance, movement, balance, decision-making, or physical contact under stress.

The goal is not to turn ordinary people into professional fighters. The goal is to provide functional options when an individual is facing an imminent threat and cannot safely escape.

Appropriately designed training can introduce people to basic physical responses, movement, environmental awareness, stress management, and decision-making under controlled pressure. It can also help people understand that the objective is not to "win" a fight. The objective is to survive, create an opportunity to escape, and get away from the threat.

Preparedness Should Be Layered

Physical skills should never replace situational awareness, prevention, evacuation planning, emergency notification, sheltering, barricading, communication, or coordination with law enforcement. They should be another layer in a comprehensive preparedness system.

A complete approach should address the entire progression of an incident: recognizing warning signs, identifying available options, creating distance when possible, moving toward safety, communicating information, sheltering when evacuation is not viable, and understanding what to do if physical contact becomes unavoidable.

This is where preparedness must move beyond memorizing acronyms.

The question should not simply be, "Do you know Run, Hide, Fight?"

The better question is:

"What can you actually do when the threat is already within physical contact distance?"

That question exposes the difference between awareness and capability.

You can tell someone to be aware, but that does not automatically create situational awareness. You can tell someone to remain calm, but that does not teach them how to manage a survival response. You can tell someone to run, hide, or fight, but those words alone do not create the physical or psychological capability to execute those actions under extreme stress.

Instructions Does Not Equal Training

The 18-inch concept is ultimately less about the precise number and more about what the number represents.

Distance matters. Time matters. Options matter.

When you have distance and time, use them. When you have an opportunity to escape, take it. When shelter is the safest option, use it. When communication can improve the response, communicate.

But when the threat has already closed the distance and escape is no longer immediately possible, people may have to act physically.

They should not be left with nothing more than a sentence on a PowerPoint slide telling them to "fight."

Preparedness should give people more than permission to resist. It should provide an understanding of the survival response, practical skills, controlled exposure to stress, and the confidence to act when action becomes necessary.

Because knowing WHAT to do is not the same as knowing HOW to do it.
