At about 4:45 into this you can see the shots being fired from much lower than the 32nd floor.

Those windows dont open. How would one shoot from those locations without leaving clear evidence in the daylight?
A Freeper pointed out yesterday that those flashes could still be seen hours after the incident ended. That should have been a clue right there.
Interesting - in the first video, the shots are pretty muted and yet the taxi driver was apparently sitting right there at the Mandalay and then they got louder...No wonder there’s so much speculation going on...
I think in the 2nd one it was strobe lights as one comment said - too consistent for muzzle flashes...
Those flashing lights are the fire alarm system set off by the smoke.
