I found the video for you that shows a bullet riddled exterior door.

Second video at the link.
The interesting variation is that they have her saying she was still in her nightclothes when the troops came in, that her parents made her wait and not go to school because of the bomb going off earlier, and they feared the troops reaction.
We see from the "third telling" with Wallid that in fact she was not going in to school...(which perhaps better explain why she never got out of her nightclothes...she had no plans to go) in anticipation of the bomb going off. Not that it had already gone off.
A clear contradiction. She was likely giving the real, uncoached version.
Another thing: Her third telling timeline makes a clear statement that it was pretty swift and immediate reaction by the troops...and they were at the houses investigating. This was not a second convoy, as intimated by the Brit reporter. This sounds like the same unit which was attacked. I don't know if we can credence this inference, or if it may make a difference, but we need to keep track of every discrepancy at this point.
