It begs the question

We were dispatched to a car wreck last night, which, en route, turned into a pedestrian hit by a vehicle. (This is common; you can't blame the dispatchers, as they are only relaying the information they receive.) We were then told to stage for the police, as a disturbance had supposedly developed. So, we sit at the corner for a moment until we see the ambulance barrel on through and go to the scene, which happens to be right outside a bar. We figure we'll follow them in. Once on scene, we are told by a really drunk and loud guy that his friend was supposedly hit by the big-ass tour bus idling in the middle of the street. "I saw everything," the drunk guy says, which is an immediate indicator that he is the last person from whom I'd want to get the story. Anyway, I'm looking at the three guys standing by the bus, one of whom was supposedly hit by said bus, and I can't tell who that would be, because they all look fine and drunk to me.

So, it begs the question--if someone was hit by a bus, but you can't immediately determine who that person is, was anyone really hit by a bus?
