Two men argue with two security guards. Another guard grabs one of the men around the neck from behind. As the other man looks back and is distracted, a security guard standing in front of him punches.
The guards flanked and overwhelmed the two men. Human only have eyes in one side of their head, and a split second of distraction is all that is needed to land a punch undefended.
Reluctant to go hands-on, police use their baton, then Taser which fails multiple times. One police officer attempts to knock over the man by rushing at him from behind but ultimately loses control as he stands up. The Taser is used again, then OC spray before the Taser is used once more before the man is taken into custody.
All of the tools police used in this instance depend on pain compliance, apart from the Taser which incapacitates for mere seconds IF the two prongs make contact correctly and in the correct positions on the body. Physical control with grappling techniques may have resulted in a faster and safer arrest, however these officers either lack those skills or were not willing to go hands-on.
