Sandra Bland died from the injuries she sustained during the traffic stop beating. On the video, Sandra claimed she suffered from epilepsy,a neurological disorder, while being held down on the pavement. It was possible that Sandra received some brain damage after the assault, resulting in a seizure. This seizure, when left untreated, will result in death. In short, the Police department will and should be held responsible for Sandra 's death. No matter how she died that officer was directly responsible for her death. He exacerbated the situation in the video for reasons unknown, we don 't know what his mental state was at that
