Knives do not immediately incapacitate – often, a person who has been stabbed is able to continue fighting for long enough to successfully retaliate, even if they die soon after. This makes knives both a poor choice for self defence, and a good choice for murder. A horrific way to fight since ancient times.
An important point to learn from this video: striking is an effective response to a knife attack, assuming that you are a capable striker. Many people tend to focus on the knife and fight to control it, not realising that this is as good a time as any to punch the face.
The Tueller Drill is a self-defense training exercise to prepare against a short-range knife attack when armed only with a holsteredhandgun.
Sergeant Dennis Tueller of the Salt Lake City Police Department wondered how quickly an attacker with a knife could cover 21 feet (6.4 m), so he timed volunteers as they raced to stab the target. He determined that it could be done in 1.5 seconds. These results were first published as an article in SWAT magazine in 1983 and in a police training video by the same title, “How Close Is Too Close?”
A defender with a gun has a dilemma. If he shoots too early, he risks being accused of murder. If he waits until the attacker is definitely within striking range so there is no question about motives, he risks injury and even death. The Tueller experiments quantified a “danger zone” where an attacker presented a clear threat.
The Tueller Drill combines both parts of the original time trials by Tueller. There are several ways it can be conducted:
The (simulated) attacker and shooter are positioned back-to-back. At the signal, the “attacker” sprints away from the shooter, and the shooter unholsters his gun and shoots at the target 21 feet (6.4 m) in front of him. The attacker stops as soon as the shot is fired. The shooter is successful only if his shot is good and if the runner did not cover 21 feet (6.4 m).
A more stressful arrangement is to have the attacker begin 21 feet (6.4 m) behind the shooter and run towards the shooter. The shooter is successful only if he was able take a good shot before he is tapped on the back by the attacker.
If the shooter is armed with only a training replica gun, a full-contact drill may be done with the attacker running towards the shooter. In this variation, the shooter should practice side-stepping the attacker while he is drawing the gun.
MythBusters covered the drill in the 2012 episode “Duel Dilemmas”. At 20 ft (6.1 m), the gun-wielder was able to shoot the charging knife attacker just as he reached the shooter. At shorter distances the knife wielder was always able to stab prior to being shot.
OC spray and Taser were used to take the man into custody following this. The police officer suffered a 6cm wound and survived.
An ambush gives the attacker initiative. They have had time to mentally and tactically prepare for the situation. The defender may not be psychologically prepared or have any kind of plan, and is at minimum a few seconds behind the attacker to even understand what is happening.
The cop who stood there for a few seconds either did not understand what was happening or was in a kind of denial for some time. This is not a conscious decision made while observing the situation. It is likely a result of inadequate training.
When one of these young men starts reaching into a bag, the other does not recognise the danger he is in, and does not react accordingly. Police pay special attention to this kind of behaviour because they may be reaching for a weapon.
Complacent police surround man and fail to maintain a safe distance or keep their weapons ready. The man is able to close the distance and stab multiple police, possibly killing one before he is finally shot.
