Video from the incident shows a McKinney police officer throwing a teenage girl to the ground and sitting on her and drawing his gun on other teens at a pool party disturbance.
The officer, Cpl. Eric Casebolt, is now on leave while police investigate.
Adrian Martin, 18, is seen on the video appearing to lunge at Cpl. Casebolt.
He was arrested and charged in the incident, but through his attorney, Martin says that he was just trying to assure a friend, the young woman being detained by Cpl. Casebolt, that someone would call her mother.
"She's yelling and screaming, 'Somebody call my mother. Somebody call my mother!'" said Martin's attorney, Heath Harris. "All he wanted to do was make sure she knew she wasn't out there by herself. 'We gonna call your mother.' And he's trying to make visual contact with her mother."
Harris says the video clearly shows that Martin was bumped twice from behind by a friend and stumbled forward toward the officer unintentionally.
"It's on a slope," said Harris. "So again, when Mr. Martin's friend comes from behind trying to make facial contact with this poor little girl, you'll see he contacts him twice. Once he gets down, he immediately starts backing up because now the officer's turning his aggression on him."
Harris calls the charge of evading arrest ridiculous because Martin obeyed the officer.
"Does exactly what that officer told him to do," said Harris. "'Get outa there!' The only command that officer gave him was to leave. First it was verbal, and then he used his gun to do it."
Martin, who did not speak to FOX 4 on camera under the advice of his attorney, said he was held for more than 24 hours.
"Initially he just thought he was being detained," said Harris.
Martin's father posted $3,000 bail on two charges: evading arrest and interfering with an officer.
Video from the scene shows Martin in cuffs with a bloody lip, but both he and his attorney wanted to make it clear that the officers who arrested him did not cause the injury.
Martin says he merely bit his lip while being forced to the ground. In fact, he says, the other officers there were calm and professional.
"Absolutely," said Harris. "It's just this one officer."
Harris thinks the charges, which are misdemeanors, should and will be dropped.
"Absolutely it should be dropped," he said. "It should be dropped immediately as a show of good faith if they want to do the right thing…the right route is get together and talk about how we can make sure this doesn't happen again. Make sure these kids understand that when an officer tells you to comply, just comply."
