But
@Harmony, I might have missed it. Do we see the collision on camera? Because if not, the statement that it was a low-speed one might be also a hearsay.
KR states it was a low-speed one. If they still can't answer if JO entered the house or not, it means that her hitting him was not on the camera. If we don't have the collision on the camera, it is KR's word only that it was low-speed.
Unless we see on camera it was low-speed, and John fell, we don't know either way. And what would be the biomechanics' opinion re. a high-speed impact?
