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

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.

Police OC Spray and baton ineffective against drunk man

Pain compliance (OC spray and baton) are ineffective against this man, and the police involved lack the skills/ability to physically control him. Backup arrives to assist, but it appears that the man could have overpowered the two police officers in the meantime had he decided to.
