A screenshot of activist, Sandra Bland, who was found dead in a jail cell in Texas after being arrested during a traffic stop July 10, 2015.
The video shows Texas State Trooper Brian Encinia approaching Bland's vehicle July 10, after having stopped her for failing to signal.
The encounter appears to go smoothly, until Encinia returns to Bland's vehicle with her documents. Encinia asks Bland if she's okay. That leads to an apparently terse verbal exchange that quickly escalates after the officer asks Bland to put out her cigarette.
Shortly after Bland refuses, Encinia orders her out of the car.
The two begin to physically struggle with each other, at which point, Encinia says "I will light you up," threatening to tase her, according to Texas lawmakers who commented on the police video released Tuesday.
Over the course of the video, Bland asks the officer why she is being arrested 14 times. The officer never gives a clear answer.
The release of the video comes after days of protests - both on social media and offline - questioning the legitimacy of Bland's arrest. She was found hanged in a jail cell days later, from an apparent suicide, according to officials.
Bland's death is being treated as a murder investigation after Waller County District Attorney Elton Mathis said there were "too many questions " to determine how she died.
Texas state Senator Royce West said in a news conference Tuesday, "Once you see what occurred, you would probably agree with me that [Bland] shouldn't have been taken into custody."
According to Bland's family, preparations were being made to post her $5,000 bond before she died.

Some anomalies can be seen in the video, beginning at 25:08, that appear to show the same two vehicles - a light-colored SUV and a blue Volkswagen Beetle - passing the scene at least 4 times. The audio of Trooper Encinia, who is apparently discussing details of the ordeal to a colleague, is unchanged.
Many more anomalies can be seen through 33:17, as noted by journalist, Ben Norton.
DPS Director, Steven McCraw said in a statement, "DPS has been working closely with the family of Ms. Bland during this investigation, and the department extends our sincere condolences for their tragic loss."
Encinia is on administrative leave, while the DPS and FBI investigate.
