Security guards beaten by soccer fans

Security guards take down a man who has invaded the field at a soccer match. The guards hit him with their batons while restrained, and the crowd intervenes and attacks them in return.

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.
