Shooting any large caliber weapon in a city will bring all sorts of false noise as various materials amplify, reflect and absorb sound waves. I’m no audio expert—damned near deaf in one ear—but I do know that audio testimony is far less accurate than eye-witness reports which vary widely from recorded events.
well, again, the audio has the police reporting victims with gunshot wounds that were away from the general area of the concert grounds, and the reports of gunshots were not gunshot sounds, but actual gunshots, as heard by a large amount of trained police, even after it was established on the audio, the shots were coming from the 32nd floor, the reports continued coming in from other areas of wounded that the gunman would have been hard pressed to get to from his vantage point.
