 What has to be done here is that you're going to have to get experts, probably at Quantico, and I know the FBI is sketchy right now, but they're the best in the world. They're going to have to slow that tape down. They're going to have to examine it audio forensically. There's ballistics that need to be collected, the shells from that rooftop, and then the other shells that could be found on the grounds to rule out a second or third shooter.
