Surviving an Active Shooter Without Weapons: Zigzag, Door Wedges, and an Ohio Study

Surviving an Active Shooter Without Weapons: Zigzag, Door Wedges, and the Ohio Study

Run in a zigzag, fall to the ground, roll, block the door with a wedge you carry in your pocket. This advice has been circulating since January 2015, when the attacks on the Charlie Hebdo newsroom raised an uncomfortable question: what does an unarmed civilian do when someone starts shooting inside an office? Eleven years later, there is still no definitive manual.

The most cited routines come from self-defense instructor Jim Wagner's videos, with two basic commands: hide near the doorframe to hit whoever enters and run away in a zigzag to make aiming difficult. The latter has generated the most controversy.

Why is zigzag running debated as an escape technique?

The counterargument is intuitive and repeated: someone running in zigzags passes through the midpoint of their trajectory, and a shooter who knows how to wait only needs to aim there. In open terrain and against someone accustomed to shooting moving prey, regular swaying would be a death sentence rather than an advantage.

The defense is more technical. A zigzag doesn't have to be regular: two meters to one side, three to the other, changing pace. With adrenaline soaring and a shooter who may or may not be trained, hitting a target that changes direction is not the same as hitting darts on a stationary board. No one agrees on this.

The Ohio Study: Same Hits, Less Lethal

The most cited test is an experiment by the Ohio police. A shooter armed with a paintball gun, simulating a Glock, fired at a thirty-yard escape route—just over 27 meters—and each round was limited to two shots.

The result was nuanced: the number of hits was practically the same running in a zigzag as in a straight line, but their lethality decreased, with fewer hits to the head and center mass. The limitations are obvious: two shots per attempt, open terrain, and no tests with automatic weapons or a nervous shooter. In a hallway or an office, the scenario changes completely.

What almost all voices agree on is the same: the technique can increase the odds, but never guarantee them.

The Wedge, Doors, and the Drywall Myth

One of the most celebrated—and most ridiculed—tricks is carrying a wedge to block doors. The objection is standard architectural knowledge: due to fire safety regulations, room doors open inward to avoid obstructing passageways, while doors in churches and some venues open outward. A wedge that works in one place won't work in another.

And even if the door closes, its protection is doubtful. Military ammunition passes through three or four drywall partitions without issue. Only brick walls, pillars, or load-bearing walls offer some protection. With a solid door, the added problem is splinters flying inward.

The Noise That Paralyzes and Prior Decision-Making

Those who have fired indoors repeat the same thing: the roar. A 308 caliber round in an enclosed space without hearing protection is deafening, and in automatic mode, it turns the scenario into something else entirely. Someone who has only handled an airsoft pistol has no real frame of reference.

The effect is not just physical. Antiestéticar paralyzes, and those who freeze lose the seconds that separate escape from a trap. Hence the less visible part of the advice: deciding beforehand that if a shot is heard, you run in the opposite direction without thinking, knowing the exits, and not leaving obstacles in the pathways.

In the only documented test, running in a zigzag, the shooter continued to hit the target the same number of times. The only thing that changed was where the hits landed.
