There had to be more than one shooter, from all the victims videos alone. By day 2 Id heard the video of the one guy and his friends who stayed under the bleachers in the concert area the entire time. It really was dark so there wasnt much to see, but you hear all the shots. And they are coming from two different sounds at two different rates of shooting, something that cannot be an echo.
Ya, I heard right away two belt fed guns, different calibers.
Just that info alone is enough to not believe the official story.
