Obviously a passed out drug user breaking the law by sleeping on the bench in the metro. He resisted arrest and came after the cop, he got was he deserved.
Look at this video in minute 5:38. The police kick that man sleeping on the metro bench. Then the man stand up {only stand up, no gun, no fight}, then the police beat him. The man is very big on the bench, so police are afraid of him and so beat him for sleeping on the bench? Too sad to see that pussy police.
