This scenario is about helping a friend being mauled by a violent attacker
Photo 1 shows a violent attacker kicking a person on the ground. Photo 2 shows a third party grabbing the attacker from the rear to secure an arm lock and immobilize him. Photo 2 and 3 show the helper instructing the victim to grab the attacker’s leg to keep him off balance (especially useful if you’re dealing with a big, strong opponent). Photo 4 and 5 show the attacker on the ground being restrained with painful joint manipulation techniques. Caution: Be sure to check if the attacker is concealing any weapons.
