How the knife can win vs the gun at close range. The 21 foot rule, also known as the Tueller Drill.

This video demonstrates some of the lesser-known mechanics of close-range combat between knife and gun.

Wikipedia:

The Tueller Drill is a self-defense training exercise to prepare against a short-range knife attack when armed only with a holstered handgun.

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?”[1][2]

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.[3]

The Tueller Drill combines both parts of the original time trials by Tueller. There are several ways it can be conducted:[4]

  1. 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).
  2. 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.
  3. 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.[5]

Cop shoots through windshield to stop killers during pursuit

The officer fumbles a reload near the end of the video. This happens when he passes his gun from his right hand into his left, and uses his right hand to unbuckle the seat belt. He then keeps holding the gun in his left hand, pulls out a magazine with his right and attempts to insert it the wrong way around. He has likely never or very rarely trained to reload his gun in this manner as it’s a fairly uncommon situation – firing a gun while driving and then unbuckling a seatbelt to exit the vehicle during a reload. Whenever something is attempted for the first time under stress, errors will almost certainly occur.

Summary of the incident below:

About two hours after a man was shot and killed near Eastern and Owens, officers attempted to stop the suspect’s vehicle but they did not comply. Officers followed the suspects, exchanging gunfire until the suspects crashed into a wall at Hollingworth Elementary School.

Kelly said one suspect, identified as Rene Nunez, 30, got out of the vehicle and ran up the stairs to the school. The door to the school was locked. The suspect in the passenger seat, identified as Fidel Miranda, 23, moved to the driver’s seat and started to move the vehicle back towards the officer’s car.

“Regarding shooting at or from a moving vehicle, our policy reads in part, it is policy of this department that officers will not discharge a firearm at or from a moving vehicle unless it is absolutely necessary to preserve human life,” Kelly said.

Officer Paul Solomon fired one round from a shotgun at Miranda. He was placed in handcuffs, provided medical attention but was ultimately pronounced dead at the scene.

Nunez, who was also injured in the shooting with police, was arrested and taken to University Medical Center for treatment, Kelly said.

Kelly said the suspects fired 34 rounds at officers. Officer William Umana fired 31 rounds at the suspects and Solomon fired one round.

Both officers were placed on routine paid administrative leave pending the outcome of the investigation.

Cop stabbed in back, partner slow to respond

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.

Police officer shot twice on door entry and is trapped, colleagues free him

A police officer kicks down a door, enters and is immediately shot twice. His body cam falls to the ground and he is trapped inside, moving to the garage where he is later freed by his colleagues.

  • Forced entry without gun drawn
  • Immediate entry failed, preferably the room could be partially cleared by carefully pie-ing the door from outside
  • A single officer entered even though multiple officers were available

Moments after the first police officer was shot, a second officer standing outside behind a tree is hit in the hand.

  • Police standing in daylight outside are at a disadvantage to the suspect who shoots from the dark inside the house

HENRY COUNTY, Ga. – Henry County police have released chilling body camera footage of the moments officers entered a home on a “trouble unknown” call Thursday and the suspect began to fire at them. Officers Keegan Merritt and Taylor Webb were both shot and are now recovering at Grady Memorial Hospital. Police said Merritt and Webb went to the home after family members reported seeing a woman unresponsive in the garage. The shootings kicked-off a 17-hour-long standoff with the suspect. Police later found the gunman, a pregnant woman and her teenage son dead inside the home. Sandra White, 39, and her son Arkeyvion, 16, were identified as the victims. Police said the gunman, Anthony Bailey, died of a self-inflicted gunshot wound. Merritt was shot in the hand and Webb was shot in the torso and hip, police said.
