Multiple prison guards fail to control inmate with attempted wristlocks and OC spray. Inmate achieves what prison guards cannot and takes down a guard by grabbing their legs.
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.
Two knocked out as they approach man
Man punches two other males as they enter within striking distance. An example of how at this close range there is not enough time to react to a sucker punch. Most people are generally not able to predict the exact moment a strike will be delivered from the hands at waist position.
