A witness with a camera caught a homeless man being punched by a Sanford police lieutenant's son, who was never arrested or charged for the incident.In the amateur video, the homeless man is seen trying to break up a fight when the police officer's son, Justin Collison, sneaks up from behind and punches the man in the back of the head.However, Collison was not finished. He took a few steps and slammed another bar patron to the ground."Justin! Justin! What the f*** are you doing? Justin, get off him!" Collison's friend said in the video."I was like, 'God, this guy, he's gotta go to jail.' You can't walk around doing that kind of stuff," the witness said.But to this day, more than three weeks after the fight, Collison has not been been arrested or charged by the State Attorney's Office or the Sanford Police Department, where his father is a lieutenant."It seems like they just thought some guy got punched. They didn't know he got sucker punched in the back of the head," the witness said.According to the police report, Collison's punch was "without provocation, with full force."In the video, his friends were scolding him for hitting people, "randomly.""Don't hit people just randomly! Stop! Don't move!" Collison's friend shouts in the video.Several minutes after the fight, the victim, Sherman Ware, was still out cold.Witnesses say they are astonished that justice still hasn't been served."I mean, there's a million witnesses and a video. What more could you want to seal a case?" said the unnamed witness.Despite the video, the police report says accounts on scene were conflicting and the victim was uncooperative. Officers said that is why Sanford police didn't make an arrest.Police requested "capias" from the State Attorney's Office, which is essentially the prosecutors' assessment of whether charges should be filed.
