According to newly released police video, a Texas trooper threatened Sandra Bland with a Taser when he ordered her out of her vehicle during a traffic stop on July 10, three days before she was found dead in a county jail. Bland - a 28-year old African American woman - was stopped for failing to signal while changing lanes, but the routine traffic stop turned confrontational after the officer, Brian Encinia, ordered Bland to put out her cigarette. Bland refused. Encinia opened the driver's door and attempted to physically remove Bland from the vehicle. I'm going to yank you out of here," Encinia said as the two struggled in the car. "Don't touch me, I'm not under arrest," Bland said. "I will light you up!" Encinia said, while pointing the Taser at Bland. State Sen. Royce West (D) said that after viewing the video, he could confirm that Bland was threatened with a Taser by the officer. Details of the confrontation were not included in the arrest warrant written by Encinia, which officials released ... eight days after Bland's death in the Waller County Jail. During the incident, Bland repeatedly asks why she is being arrested. The remainder of the confrontation occurs outside the view of the camera, but the audio captured what appeared to be a struggle. On Wednesday, authorities responded to allegations that the dashcam video had been edited from its original form. The video uploaded by state officials to YouTube contains visual sequences that appeared to repeat themselves.
