The methods used by police in this example are typical of those used by people who have very little grappling experience – holding wrists and pressing down on the head without controlling the body. Two police hold the man who has been arrested for possession of a knife in a public place, while a crowd gathers which becomes a safety concern for the officers. Although the methods used are not causing harm (the suspect is lying on his side rather than face down, most of the officer’s weight is on his own feet and the knee is pressed into the head rather than neck), the knee on the head resembles the George Floyd incident which could quickly incite the crowd to intervene.
It is very likely the man was actively resisting and attempting to escape custody before this video clip starts, however it would not make sense to continue once he saw that a crowd had gathered and was filming. Playing the victim only makes sense, whether it is right or wrong. This video resulted in the police officer being suspended.
Matt Serra, shown in the second video restraining a man who had just threatened restaurant staff and attempted to punch him, sits in the mount position which has the man immobilised. Serra controls the wrists only to prevent him from grabbing and hitting, not as the primary method of control. It also allows the man to breathe and causes very little discomfort.
Aside from maintaining enough distance to not get hit, closing the distance against a blunt weapon is the best option. Moving into a clinch removes most of the advantages for the weapon.
Conversely, stepping away keeps you at the effective range which is very bad. The victim here was slow to respond and took a lot of damage, but ended up in a better position toward the end of the video where it ends without a satisfying conclusion. The aggressor even threw away the stick when he realised that it may now be used against him.
The victim is stabbed repeatedly. He used everything he had to defend himself: punches, kicks and throws, and attempted two eye gouges and two groin strikes.
None were effective -the assailant moved his head away when eye gouges attempted and blocked kicks to groin.
It should also be noted that although the victim was stabbed many times, he was still capable of fighting and managed to escape – neither person was incapacitated, and both were capable of continuing the fight.
Seeing police in retreat, the crowd mistakes this for a lack of will to fight. Once a police officer falls and has their gun taken, his colleagues return and now have a justification for use of deadly force.
