I believe I saw this video about 2005-ish, so it could be much older than that. An old-fashioned challenge match where a pure Karate man has entered a BJJ (or possibly Vale Tudo) gym and challenged them to a fight, somewhere in Brazil.
Back before MMA was popular, many people completely underestimated the importance of grappling skills and believed they could prevent takedowns and never go to the ground, despite having zero experience in takedown defence and grappling.
A higher quality version of the video is available on my youtube channel.
After making this video, I found a 1-hour long interview with Viktor. I definitely recommend watching this interview. He offers insights into his thinking during the confrontation, talks about his past experiences with violence and how this lead to his training and MMA career, and they broadly discuss violence what motivates young men to engage in this kid of behaviour.
BJJ black belt Idriz Redzovic takes down and controls a man who assaulted staff in a shop. Idriz uses the “gift wrap” method to maintain control for an extended period without any harm to himself or the belligerent man. He hands the man over to police when they arrive without issue.

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.
A power lifter is knocked out by an amateur MMA fighter, falling on a hard surface which resulted in his death. What begins as nothing more than a contest of egos ends with severe consequences.
