Fair enough, but the point about them not shooting at stationary targets with both feet firmly planted is perhaps not quite so valid considering all the people were tied up at the time. From what I read, apparently the police got the little girl to re-enact the events with dolls and what she saw was the killers shooting the people at point blank range to the head, so I doubt they emptied their magazines :P
But anyhow, since I've never held a gun nevermind fired one I can't really comment much.
