The only reason this cop pulled Sandra Bland over was under the excuse that she pulled over to get out of his way without a signal. The he arrested her for resisting an arrest he had no cause to make in the first place. I believe that her death was a suicide, but it was still a murder too.
But this is America, so the cops all got away with it clean. All government employees are above the law. They could have chopped her up with a hatchet and still would have only gotten two weeks paid vacation.
