Remember that the police had a routine cop shooting on Saturday, and they did read the reports, and everything was normal, until Monday, when they received this video.
They then charged the cop with murder.
Under the circumstances, it is ironic that you use “Innocent until proven guilty”, for the representative of the law who was videotaped conducting the murder of someone that he judged, and murdered, and then appears to have planted a weapon on.
Something was dropped by the driver. If it was a tazer, it will be obvious how far the driver fled after dropping it by the amount of wire spooled out.
Give the investigators a chance to do their job, Holder is already on it, it is no linger local or regional investigators.
