Unless more video becomes available or the trooper changes his story, all the evidence we will ever have that an assault took place is the trooper's word. So, a judgement on this is really a judgement on the character of the trooper as to whether or not you think he might lie or exaggerate his account of events in order to attempt to cause a certain result. My opinion of the trooper's character is not favorable in this respect. Without regard to our conclusions about the trooper's character though, we ought to at least be able to agree that it was never necessary for the trooper to order her to exit her car, and thus it was not necessary for Bland to be jailed.
