This is from a tourist video. The guy will point out where the possible shooters are at. But it looks like their shooting simultaneously and possibly in different directions. Theirs also a helicopter flying in front of Mandalay Bay. It does have a strobe on the back of it so some people say its the strobe reflections on the glass but idk... but if you look while the strobes going it looks like muzzle flash coming from the middle of the helicopter too around the same time as the other shooters shoot. Just wanted your thoughts on this one.
