Things always happen a particular way, regardless of peoples memory of that event. Case in point, a video camera can sometimes give an accurate retelling of the events at a particular place at a particular time.
A video is closer to the event than a textual retelling, but is still only a proxy. The choice of camera positioning can significantly change the viewer's perception of the event, and the narrative formed.
Ok then let the accurate retelling be defined as the view from all angles. One need not interpret events that transpired before to interpret the action because thats where bias in news comes from. It comes from trying to infer meaning and deduce reasoning with no factual proof. Actions speak louder than words so its more important to describe the action than the intent
