I never believed the cover story.
I heard automatic 5.56 at the same time as semi auto .308.
Two shooters, minimum.
I remember the discussions about two separate sets of muzzle flashes from the direction of the suite.
There was also discussion about reloading times and the pauses in fire on both video and recorded audio.
Two shooters makes a LOT more sense than one doofus.
Absolutely two shooters, at minimum. I watched the live video interviewing a taxi at the hotel entrance and I could hear what was obviously two different guns.
