The process of how police do their job must change. Particularly the methods of arresting. It is typical these days that citizens are forced to lay on the ground while Officers place their knees on the backs, heads or any part is of the body while applying hand cuffs. This act alone is a form of punishment inflicted upon a citizen without due process. This method is applied whether the subject is complying or not. Avoiding the pain inflicted during these types of police actions are enough to escalate a situation into a major incident.
The act of Officers placing the knee in the back or on the head of a person laying upon the ground bearing all of the officer weight upon a subject should be BANNED immediately. The role of police is not to punish, obviously the training given to police utilize these methods and should be removed from their work instructions. Due process will determine if a citizen needs to be punished, not the police.
