The whole scene reeked of being staged. I wouldn't be surprised if it was filmed some time ago and was just shared online like a scene from a shaky-cam movie. Notice the guy with the camera looks at the gun pointed at the girl, looks at the girl, looks back at the gun. Not once did he yell to the girl "Hey, he's pointing a gun at you, stop! Don't go in!" The guy with the gun made no attempt to yell at the girl to stop coming in the window, just hid at the wall just out of sight and the second she starts to go into the window he steps out, shoots, and then ducks back into hiding. The guy with the gun also fired at the girl without warning or any commands to cease her actions while there were several law enforcement officers right on the other side behind the girl who immediately go to her aid. Regarding the officers responding, they make no attempt to perform any kind of aid to her. They play acted like they were checking her, didn't immediately cut off her neckerchief so they can access the wound, didn't apply pressure to the wound, one spends time fumbling around on his belt and takes out something and then immediately shoves it into a different pocket. All of this while yelling at people to get back and not giving the girl the aid she needs. Even some guy walks up with a selfie stick, takes his phone off of it and is like "Dude, was someone shot?" despite having been within mere feet of the gun going off and people yelling that she was shot and he then tries to take a picture of her. When a gun goes off within 10 feet of you, you know, coupled with people yelling she's been shot and all yelling to get back. Then in the rest of the video everyone down the corridor and around the corner all the way to the door at the end of the hall is perfectly clear down the center with everyone completely against the walls like a bridal reception line waiting for the bride and groom to come out of the church after being married. Everyone immediately got against the walls and cleared the aisle all the way around the corner despite mere seconds passing since they said make a path so they could get her out. A guy mere feet away from the gunshot didn't even seem to notice it go off or see her fall to the ground and even had to ask the dude with the camera if he said someone just got shot, but everyone down the corridor acknowledged the gun went off, that someone was shot, that they were bringing her down the corridor and to make a path all within seconds despite all of the noise, all of the shouting and all of the chaos. So much more about just this one event from the day that reeks.
