The Threat is Real, very real.

I haven't heard anything in all the videos, and I've watched/listened to many of them now, that indicates a second shooter.

I've heard a lot of automatic fire from support-by-fire positions when maneuvering as an assault element, to include both 5.56 SAW and 7.62 NATO M60 and M240 fire, including in urban environments at distance. The first time you hear machine-gun fire in an urban environment, you hear the supersonic mach waves of the projectiles, then the muzzle report, and quickly work out in your head what one gun versus two guns sounds like. Echoes in the urban terrain can be very deceiving to someone who hasn't heard it before, but it only takes a little while to distinguish what is what.

When 2 or more guns are rocking, it's pretty easy to tell. I don't hear that in any of the videos that have been posted, and given the stacks of Surefire 100rd mags he had plus the Bumpfire stocks, I'm not seeing any inconsistencies in what he was able to do as a loner. Not saying there was a 2nd shooter, but everything appears to be consistent with a single shooter at this point.

One of the more overlooked physical tasks he had to pull off was breaching those windows, which are tempered very strong and have laminates applied to them. The vet in one of the floors below him said he heard explosions, then automatic fire, and could tell when he switched between 5.56 and 7.62 caliber weapons. I'm wondering if he used some of the Tannerite or improvised explosives to blow out the windows, then clear the glass with the small sledge hammer. Even after being cracked, those windows are not easy to displace for firing ports.

Another big question is where was the video he set up being streamed to? Sheriff Lombardo (who has previously stated that he supports magazine capacity restrictions) said the suspect used an unusually high bandwidth of internet data to stream to some other location overseas.
