Having watched the video several times, it seems clear to me that she immediately provoked the officer. We do not know what she did while driving that prompting being pulled over, because improper signaling isn't typically a guarantee for being stopped. She may have been swerving in and out of lanes, or switching back and forth in a reckless manner. If you look at her FB page, she has post after post of hate language and pictures that declare she hates LE and police. She seems admired by her friends for her outspokenness and her aggressive nature. When the officer stopped her for the lane change issue, she was immediately belligerent and difficult to say the least. My guess is that her tone and attitude started the entire interchange off on a bad note, and when she refused to comply, the officer became very aggravated with her. When she argues and refused to cooperate and became mouthy, he knew that she was escalating out of control. He needed her to put out the cigarette because with her attitude and behavior, she could use the cigarette to burn him. When she refused to comply, the was out of line and being difficult, which was her undoing. Then she refused to step out of the car. He asked her several times, then ordered her, and she continued to refuse. Her behavior could very easily have been interpreted as resisting. He had to get control over the situation because she was so uncooperative. I think that he felt he had to be firm to try to get through to her, and then her behavior made him angry toward the end. She had to be arrested. He could not let her get back into her car and drive away. She assumed the worst and got the worst. But, her death was not at this officer's hands, and my guess is the same issues that caused her to be angry, aggressive, outspoken, etc., are the same issues that caused her to hit rock bottom when things did not go her way. It is very sad, because she could have done much good to improve relations had she just handled things differently. It is even sadder that people who feel strongly as she did, cannot see that their own behavior plays a role in this bad outcomes.
