After watching the video, Texas state Sen. Royce West (D) commented that "once you see what occurred, you will probably agree with me she did not deserve to be placed in custody." It is likely that the United States Supreme Court would also agree.

Newly released video of Texas State Trooper Brian Encinia arresting Sandra Bland, an African American woman who was found dead in her jail cell three days later, shows the officer rapidly escalating a minor argument over a cigarette into a forcible arrest. Shortly after Encinia brings Bland a warning citation for changing lanes without signaling, he asks her to extinguish her cigarette. When Bland declines to do so, the officer opens her door and tries to physically remove her from her car. He eventually draws what appears to be a stun gun and screams at Bland that he will “light you up” if she does not exit the vehicle.
