Two vehicles collide at an intersection. For this example, exclude weather and time of day.
FOUR people are present; the driver of vehicle 1, driver of vehicle 2, a pedestrian across from the accident and a policeman in a stopped patrol car.
How many possible "stories" are there about what transpired?
1. the driver of vehicle 1
2. the driver of vehicle 2
3. the pedestrian's
4. the police officer's
5. what ACTUALLY happened
Agreed with Mr. Backer; an eyewitness is oft the worst source of evidence.
