Obviously he's afraid of the repercussions of using force. This could have been the end of him if this individual had had a knife in the hole and decided to stick him. Secondly his hand to hand skills looked terrible. He barely survived an obviously untrained teenager who looked to be an average sized young man. Not a 6-5" prison muscled recently released convict. Due to being out of shape or lack of good training, this officer was minimally effective with respect to his ability to physically apprehend the guy. If the persecution of cops continues by their own DA's then we will see the worse outcomes happen a lot as the bad guys figure out the police are fighting with one hand tied. Karma is a bitch and I hope the guy taking the video experiences it some day with respect to first responders.
