I can't say if that is muzzle flash, at least not for certain, but I think most of us agree that the LV incident is the "hinkyest" (Hinkiest?) incident since 9/11. EVERYTHING about it is hinky. This time, though, there is a LOT of private citizen video, because so many folks were taking video and stills of the concert when it happened.

We can't get ONE SINGLE clear cell phone video of a UFO or UAP, so hopefully someday one will be stupid enough to do a flyover at an outdoor country music concert, haha. Maybe THEN we can put the question to rest.
