I repeat Woodcock said the bottoms were around the knee area. If he Ralph had been dragged it is more than likely the bottoms would have come off completely.
It has yet to be explained how there was no signs of burning, or bullet holes in the said pyjama's.
Just to go a little further in this case. Hammersly collected, and took possession of 22 empty cases from the scene along with at least 4 full bullets making at least 26. We know that further ammo was found later. What's all this about?
