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.

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.

Two bouncers knock out two people with punches, slaps

Excessive force on behalf of the bouncers, and idiocy on behalf of the drunks who initiated with aggressive posturing and continued to approach after it was obvious they were outmatched.

The first bouncer kicks his downed opponent in the groin after he falls. The second slaps him down again when he gets up and refuses to leave. A friend attempts to intervene and is punched.

Man attempts bite on ground and is beaten unconscious for it

Gaining top position on the ground creates a significant advantage. It is very difficult to escape or retaliate from there, even with “dirty” tactics. In this instance, the person on the bottom cannot escape so attempts to bite, which only escalates the aggression of the other man who then beats him terribly.

Bystanders choose not to intervene, deciding that the beating is justified. If the man had not announced that the other had bitten him, they may have felt and acted differently. The opinion of bystanders is paramount and they need to be communicated with for this reason.

Aggressor knocked out by bystander then returns to attack victim

Any fight in a public space can be seen and judged by other people. There is always the potential for bystanders to intervene in any capacity – they may stop the fight by using physical restraint or attack someone involved when they perceive their behaviour in a negative way. Quite often, bystanders will actually prevent others from intervening so they can see how the fight unfolds.

In this case, a person intervenes to prevent what he saw as an unfair attack, then left too soon as the aggressor returned.

Cops fail to control man who is passively resisting

These cops first attempt to control the man by grabbing the wrists, just as they have been trained to do. The suspect passively resists, denying control. The cop then moves to the schoolyard headlock which is similarly effective. OC spray is then used which also apparently does not work. A second man begins to intervene. Video ends with no resolution.

Bystander assists cop when knife search turns into struggle

Suspect attempts to flee when a police officer searches him. As the struggle begins, a large knife can be seen tucked in to the rear of his belt. The knife falls to the ground as he escapes the grip of the cop. As the cop again grabs the suspect and pulls him to the ground, a bystander who apparently has some training in grappling assists by controlling the legs of the suspect. The bystander then transitions to a rear naked choke which effectively restrains the suspect who stops resisting.
