The Tueller Experiment was published in 1983, and it has held an honored spot in inaccurate training dogma for decades. A new peer-reviewed study recently looked at the 21 foot rule, and their findings show what we should have already known. 21 feet does not equal safety from an assailant armed with an edged weapon. The new study suggested a revised distance of 32 feet, but it still leaves a glaring error.
We are asking the wrong questions here. Both studies looked to determine the distance at which an officer can draw and fire 1 shot on an assailant with an edged weapon. What's wrong with this question you might ask? For starters, we know that 1-shot incapacitation with a handgun is unlikely. While the study did examine accuracy, the measure of accuracy was hit or miss, and it didn't look at location of hits and how they correlate to potential incapacitation of a threat.
In spite of the errors, the study did solidify 1 imporant training point. When faced with an assailant armed with an edged weapon, getting your feet moving may do more to save your life that firing your weapon. Rapid lateral motion had the most effect, followed by a backpedal, with a 45 degree advance being the least effective. Even still, movement in any of the tested directions increased survival odds.
If you're teaching firearms or serving at the academy level, please stop using the Tueller Experiment as gospel. Armed self defence is a far more complicated subject that can't be examined with the shot timer alone.
The 21-foot rule has been a topic of conversation in law enforcement since the 1980s when Salt Lake City Police Department Lieutenant Dennis Tueller developed a training drill for his fellow officers. In this drill, an officer played the role of a suspect with an edged weapon who would charge another officer who was standing about 21 feet away with a holstered weapon.
An average person could cover 21 feet in about 1.5 seconds, which was also about the amount of time it took an officer to draw and fire their sidearm. This led to a belief that 21 feet was adequate time to recognize and engage a charging armed attacker.
ALERRT Executive Director Dr. Pete Blair reviews the results of a study conducted by ALERRT and Missouri State University to determine if 21 feet is indeed a safe distance when confronted by a charging suspect armed with an edged weapon.
