Everyone is getting caught up in muzzle flashes, strobe lights, reflections, echos, blown out windows...etc. Watch the 18 minute taxi cab video here. The 45 second mark CLEARLY shows without a doubt that there was a second gunman. That is NOT an echo. Whether from Mandalay or somewhere else (I’m going to say 200 yards away) it shows there was a second gunman at a different location...period. Listen at the 45 second mark.
