Facing Down Taser, Sandra Bland Was Told By Officer: "I Will Light You Up!"

Ms. Bland, an African-American from the Chicago area who had come to Texas for a job at her alma mater, Prairie View University, was arrested after she was stopped July 10 for a failure to signal a turn.

The video also confirmed an account from the family's lawyer that the confrontation between Ms. Bland and the trooper, Brian T. Encinia, escalated after she refused the officer's order to put out a cigarette, said [State Senator Royce West, Democrat of Dallas].

Neither the Taser nor the confrontation over the cigarette were mentioned in Officer Encinia's incident report, which was released on Tuesday by the Waller County district attorney's office.

In a press conference late Tuesday, the director of the Texas Department of Public Safety said that Encinia failed to "maintain professionalism" throughout his interaction with Bland, and that he has been taken off the street and placed on administrative duty for duration of the investigation into Bland's death. In answer to a reporter's question, Texas state Sen. Royce West said that the dash cam footage showed that Bland should not have been taken into police custody.

The subsequent death of Bland has continued to raise troubling questions since she was found hanged on the morning of July 13. A medical examiner report and the county sheriff's office ruled her death a suicide, but during the three days Bland spent in jail, Bland's family members said they spoke to her on the about posting bail, and that a suicide seemed "unfathomable." An hour before she was found, Bland had asked to use the phone again, county officials said.

On Monday, officials in Waller County released additional details about the morning Bland died, including surveillance video footage showing the hall outside of cell 95, where Bland was held. Citing interviews with family members and with the bail bondsman who was among the last to speak with Bland, Waller County District Attorney Elton Mathis said it is "too early to make any kind of determination" and that "this investigation is still being treated just as it would be a murder investigation," signaling that he had not ruled out any motives and would explore all leads and evidence, including videos, fingerprints in her cell, and the plastic bag found around her neck.

The Bland case is the latest in a string of high-profile incidents around the country that have highlighted the strained relationship between the African-American community and local police.

Around two minutes into the 52-minute video, Bland changes lanes without signaling, and the police officer pulls her over. After several minutes while the officer sits in his cruiser, presumably going over paperwork, he returns to the vehicle to find Bland is upset.

"You seem very irritated," he says. She responds by saying that she only changed lanes because she felt the officer was speeding up behind her.

The officer then asks Bland to put out her cigarette, and when she refuses, he orders her to step out of her car. When she refuses, he opens her car door and orders her repeatedly to step out, while she argues that she did nothing wrong.

The encounter soon turns physical.

"Step out or I will remove you," he says repeatedly. "Get out of the car now, or I'm going to remove you. I'm going to yank you out of here."
