I want to be clear, I'm not convinced that there are multiple shooters. However, what I will say is that the audio evidence from ONE PARKING PLACE, doesn't really add up in my opinion.
I've spoken with a gun expert who says the distance of the second window "could" account for the "Distant Sound" or that possibly the shooter pulled his barrel back into the room a bit. But all things considered it does seem wierd.
At the risk of being "that guy" I just wanted to share what I had noticed from one of the more viewed recordings from the horrible Las Vegas shooting. I listen to audio all day every day and it just didn't sound right. The video I was listening to is being called "The Zapruder Film" from Las Vegas.
