Quite typical in street confrontations – while focused on fighting a single person, we are extremely vulnerable to attack from others.
4 police fail to control 1 man
A bystander initially approaches the man from behind while he is focused on the police, grabs him around the waist and effectively takes him to the ground. Police move in, then escort the bystander away and attempt to control the man with arm/wrist holds. When they fail at this and the man struggles free, they deploy their batons and strike him several times to little effect. The man eventually is able to walk away and the police follow behind by the end of the video.

Security guards beaten by soccer fans

The chief mistake by the guards was failing to appreciate how their actions may appear to bystanders.
Bystanders assist arrest with effective control
A police officer struggles to arrest a man by wrist control alone. Two bystanders intervene and clinch with the man around the upper body. One of the former bystanders transitions to control the legs, and together execute a very effective takedown and control of the man. Throughout the takedown, the police officer continues to attempt some kind of wrist/arm control.
Killed with hammer
A man is seriously injured, possibly killed with a hammer. This illustrates how deadly such an item can be, and why a person wielding something like a hammer must be treated as a deadly threat.
Slam while applying submission from ground
MMA fighter attempts triangle choke from bottom ground position. His opponent raises and slams him into the floor, resulting in a knockout. This is exceptionally dangerous and would most likely result in death on a hard surface.
This can be avoided by using techniques which break the posture of the person attempting the slam and bring them back to the ground, or by abandoning the technique as below. The slam is attempted by the same MMA fighter as the above video:
Knife wielding man stabs multiple police
