Atlantic City police brutality caught on video, K9 officer purposely uses dog on knocked out man

Atlantic City police brutality

Video can be very good proof when things happen, in this case it looks like the officer has a man on the ground and the man appears to be knocked out, as the man is lying on the ground and not resisting, the officer commands his K-9 to attack, but for what reason? You have the man on the ground, obviously not resisting and not even conscious or he would have screamed when he was attacked by the dog, at least three other officers on scene that could have went hands on to aid in cuffing the man.

I see obvious excessive force here with the dog and a cop that has poor judgement, does he deserve to be punished? One problem that I have is that the video tape doesn't start from the beginning so we don't know the events that lead up to the man being put on the ground and we don't really know the reason for the officer using the dog. In all actuality the officer could have been justified in that use of force, but from what I see in the video, the man is not resisting but he is simply not conscious so he can't comply.
