Leg lock used to control fight at basketball court

The black male leans forward, revealing his intention to attack as his posture has shifted to load up the punch. The white male immediately clinches and falls to the ground, pulling the other with him. He is obviously very confident on the ground and does not mind which position he initially ends up in, as long as it is on the ground.

The black male grabs the other in a head lock, which is a terrible idea against an experienced grappler as it allows them to take the back.

Others intervene for a second but the fight eventually ends with the white male threatening to destroy the leg of the black male, which is not a hollow threat as he is holding a heel hook.

Man threatens another with baton, gets knocked out

The man holding the baton made some errors:

  • Allowed his opponent to close the distance when he had a tool which needs more range.
  • Range can be managed by movement – he’s completely stationary.
  • Flat posture, straight back, very likely standing with knees locked straight, does not appear to be in any kind of stance which would prepare him to respond in the split second required to move, defend or attack. His opponent constantly adjusts.
  • Allowed opponent to grip his wrist. Difficult to swing baton effectively when grappling starts. The grip even from this position may allow opponent to stay off-centre when the baton swing comes.
  • Furtive glance made by opponent is a huge warning sign. He has already decided to attack at this point and is looking for witnesses, other enemies or allies which may factor in to his decision to go ahead.
  • Even if he decided to use the baton, it’s a poor weapon. Law enforcement use this as a method of pain compliance, and often need to move to other methods when it fails. Striking the legs is unlikely to instantly shatter kneecaps unless you’re very lucky/unlucky to hit that spot. You’re only starting the fight, not ending it. Swinging to the head would be a different matter.
  • Compare the above (pain compliance) to the punches thrown to the head (incapacitation).

Baton man seems to think intimidation is enough to keep him safe. The baton is like some kind of force field, everything else can be ignored.

From this position, when would he decide to use it? Once the fighting starts? Too late, too close. When the man fails to step back? This may be considered unjustified assault. Baton man then made a threat to seriously harm, which prompted an aggressive response. He put himself in a situation which is very difficult to win.

Knife disarm via punch to head and control on ground

Rather than reaching for the knife when it is drawn as many people tend to do, this security guard punches the man, and as they go to the ground he and controls the hand holding the knife. He extends the hand away from the body which prevents the man from reaching for it with the other hand. Bystanders step in and assist. Excellent instincts.

Belligerent man pushes woman, is stomped by 3 men

Belligerent man attempts to intimidate couple, pushing a female in the process. He seems to regret this a split second later as he reaches to hold and prevent her from falling.

Unfortunately he has already failed miserably to take stock of the situation he is in – alone, drunk, surrounded by bystanders who may not tolerate his behaviour.

Man overdoses and is revived by firefighter, kills the firefighter, uses female bystander as shield, is shot by police

A strong case for handcuffing and searching people who have overdosed before reviving them. Background info:

When the bus arrived at transit center, a bus passenger believed Houston was having a seizure and called 911 for help. Lundgaard arrived with other firefighters and began providing aid to Houston.

Houston regained consciousness after responders determined he likely had suffered a drug overdose and gave him two doses of Narcan.

Houston told responders he had taken some of his wife’s morphine. Houston got off the bus on his own, even as responders were encouraging him to seek additional medical care, but he refused.

“They wanted to make sure he got that help,” Tempelis said.

Houston drew a small handgun from a small case at his waist, Tempelis said. He stood back and fired twice, hitting Lundgaard in the upper back and Christensen in the upper leg.

Almost simultaneously, Christensen drew his handgun and fired once, striking Houston in the abdomen. Houston ran toward where bystander Brittany Schowalter was and used her as a shield, the district attorney said.

Christensen and Biese both fired multiple times at Houston, also likely striking Schowalter, although Tempelis said it’s impossible to know for sure who shot her. She suffered an injury to her leg and to her head, with a bullet grazing her skull, Tempelis said.

Houston eventually went to the ground, which allowed officers equipped with a ballistic shield to arrest him. The officers found Houston’s gun under him, Tempelis said.

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]
