Watching dashcam from Sandra Bland and the previous traffic stop. The former is a white girl who was caught speeding and let off with a warning. Didn't even have insurance, and the cop tells her to have her dad fix that up. Sandra Bland is pulled over for failure to signal and, while irritated, does nothing to warrant the out of control reaction from the officer present. She clearly narrates the contradictions between her behavior and the officers overreaction. She also notes several times when the cop is behaving counter to the law.
While she wasn't demurring and friendly like the previous stop, Bland was NOT threatening in any way. The officer immediately asked her to step out of the car when he asked her to put out her cigarette and she voiced mild displeasure at having to put out her cigarette when she was smoking in her own car. The officer told her again to get out of the car and opened her door. Bland states that she is not required to get out and only needs to give her name, and that she's calling her attorney, at which point the officer reaches into the car to stop her.
Bland is upset, but does not yell or scream, but the officer continues to get louder and louder, and calls for backup. Bland continues to talk, and this clearly angers the officer.
"Get out of the car. I will light you up. Get out of the car," he screams.
Bland then steps out of the car and walks calmly to the curb. She obviously knows she is being recorded, or at least hopes so, because she continues to talk. She repeatedly indicates that the stop was for failure to signal a lane change and that she's more than willing to take this to court. The officer tells her repeatedly to get off her phone, but at this point we can no longer see them in the camera. Bland indicates her right to her property, but the officer continues to speak loudly to her, commanding her to put it down. The two are briefly seen again on camera as she puts her phone on the trunk of her car.
The officer yells at her to "come over here" and "turn around", at which point Bland likely knows that she is being arrested. She still talks through this entire scene, saying that it's bullshit and asking the officer if he's proud of what he'd doing.
As you hear the handcuffs being tightened on her wrists, she's talking about how the South Carolina cops have them scared of a woman and more about her deepening interest in going to court over this matter. The officer shouts at her to "stop moving". The officer then pulls her back into camera behind her car and tells her that he was going to give her a warning, but now she's being arrested.
He then pushes her over to the curb again, and she starts yelling that he's "breaking" her wrist. He tells her to stop moving around, and she counters that he's the one moving her around. At no point has she made any violent movements.
At 13:20, she starts screaming about her wrist off-camera as the officer instructs her to move again. This is likely where he has put her down on the ground. She is now crying and it sounds muffled. He continues to scream at her to "STOP IT", that her "jerking around" is resisting arrest. At this point another voice can be heard, which is likely the backup he requested.
All of this happens off-camera.
At 13:55, she states that her head was slammed into the ground that that she has epilepsy.
"Good... Good," the officer responds.
After some more noise and complaints of the officers knee in her back, the officer and the backup coordinate to move her to the other officers car. Around this time, the officer is telling someone "You need to leave" three times.
It seems that they then bring her back to the side of the officers car and where he again explains that she was going to get a warning and now she's being arrested. Bland is crying again, states she cannot feel her arms, and that she cannot hear. The female (unknown) officer assisting tells Bland that she can hear, though how she would know this is unclear.
At 15:18, Bland says, "All this for a traffic signal. Thank you for recording! Thank you for recording!!"
At this point, the original officer, a female officer, and an additional male officer can be seen in the camera, and start talking. The female officer starts searching Blands car, while the male officers can be heard talking about how Bland kicked him and chuckling.
In my estimation, Bland's body language indicated annoyance and righteous indignation, but was not enraged or violent in nature. No. I'm not a psychologist, but I play one sometimes. You can watch it yourself. If there was a kick, it was well past the initial non-incident that the officer inflamed unnecessarily.
If you continue watching the video log play out to around the 23:00 minute mark, you can hear the officer describing the events that just occurred to an unknown person. At no time does he indicate that he was belligerent, but calmly claims he was trying to calm HER down. He also claims that she was jerking and stomping around.
