DALLAS -- A man is suing the Dallas Police Department because he says his civil rights were violated.
Dash camera video shows Albert Butler driving down the road after a trip to the grocery store. He abides traffic signals and drives safely, yet he is pulled over for an unsafe lane change.
“I didn't do anything," Butler said.
The video shows him waiting several minutes until Officer Brian Bradley orders him out of the car and then begins searching him immediately.
"He was not resisting," said Butler's attorney, Daryl Kevin Washington. "He was not being disrespectful."
The officer ordered Butler, who is 59 years old, hearing impaired, and has a leg brace, to the side of the vehicle. He seems confused.
Then you see the officer push Butler from the view of the camera. Butler says that's when the officer beat him.
"So he grabbed me by the neck, and threw me to the ground, choking me," he said. "He drug me where he wanted me, and he just took action on his own."
Butler, who later had to be taken to the hospital by ambulance, said he cried for help.
"I was doing all that hollering and screaming, and crying out to God, 'Please, make him stop,'" he said.
Officers searched his car and found nothing. His attorney is suing, claiming there was no probable cause to pull him over, search him, and use force.
"Mr. Butler did not resist and ended up on the ground, basically struggling for his life," Washington said.
The incident happened in December 2012. The Dallas Police Department conducted an internal affairs investigation and cleared the officer on the excessive force allegation.
Butler finds that hard to believe.
"Choking me," he said. "I mean, I couldn't breathe. I vomited and almost passed out."
Since 2012, the Dallas Police Department has paid nearly $6 million for civil rights violation cases.
News 8 asked the department for comment on this case, but they did not respond.
