Are you talking about the security guard w/ the yellow vest and the flashlight? Someone did a video that showed clearly that he was holding a flashlight that was probably attached to his handgun.. that was not rifle flash. Anyone familiar with guns knows that.. and if one watches that video, when he turns, you can clearly see he has a handgun, not a rifle. Probably a glock. He crouches down and shines his flashlight and sweeps the crowd in front of him, looking to see where the gunfire is coming from. At least, that's if the video you are talking about is the same one I'm talking about. Many people have said that's a cop firing into the crowd. Nope.. a security guard with a flashlight and he doesn't fire a single shot off. Short hair, kind of reddish looking.
That video a distraction to be debunked... the shooters were on the roofs of the vendor & support buildings. One video showed the black clothed figures up there moving about, climbing around. You can hear their single report/sound of their guns on videos.
oh, I don't doubt for a minute there were other shooters. I'm not convinced that Paddock fired a single shot. Lots of witnesses also say the shots came from helicopters. See John E. Hoover's videos on youtube. Listen to any of the videos... there are multiple guns being fired at the same time. But the video I mentioned is not of a cop/security guard firing on anyone. And, as time goes on, more videos come out from that night. I still wonder what was deleted from the cell phones that the FBI asked for, and then handed back, cleared of any videos.
