William McNeil Jr. joined African American civil rights attorneys Ben Crump and Harry Daniels at the National Bar Association’s annual convention.

One hundred years ago, the association was created because African American attorneys couldn’t join other organizations. At that time, the issue was to prevent racial profiling, which led to lynchings.

The attorneys spoke about the body camera video released by the Jacksonville, Florida sheriff’s office.

The video shows McNeil arguing with officers before one breaks a window, punches him and pulls him out of the car.

Attorneys addressed a new angle of the video showing an officer pointing a gun at McNeil.

McNeil also recorded video during the traffic stop.

Jacksonville police determined that officers did not do anything criminal during the encounter after an internal investigation.

Police say McNeil was pulled over for not having his lights on in the rain.

The video then shows McNeil locking himself inside the car as the officer repeatedly orders him to exit the car.

McNeil is heard on the video asking for a supervisor.

He says he broke a tooth and got a concussion.

McNeil also described the emotion and psychological impact .

“Traumatized, still afraid of police, still frightened at night,” McNeil said.

In the police report, an officer claimed McNeil was reaching for a knife.

McNeil’s lawyers deny that, and the video does not appear to show that action.

“I was telling the truth. As evident in the picture, I was being held at gunpoint; I didn’t feel safe,” McNeil said.

Several attorneys prayed with McNeil Tuesday, vowing to clear his name.

“No way he should have been charged with a crime: Because, let me be very clear, the stop was unconstitutional,” Daniels said.

McNeil was charged with driving on a suspended license and resisting arrest.

“A hundred years later we are reminded that we have more fight to do,” Crump said. “He never escalated anything; he was never fighting. He’s a college student.”

John Burris, the former attorney for Rodney King, was also at the conference.

“You saw Rodney king. You saw this. What you are really seeing is a continuation of 35 years of brutality that’s occurred,” Burris said.

Attorneys plan to file a federal civil rights lawsuit on McNeil’s behalf, and want the officer involved fired and prosecuted.

But the state’s attorney for Jacksonville has said none of the officers would face criminal charges.

The Rev. Jesse Jackson Sr. was scheduled to attend the conference.

Crump said Jackson was not well enough to attend, but they hope he can attend later this week.
