2nd video from Tayler Hansen
I downloaded a longer version of that vid; it starts with a close-up of the hand and gun, and shows the shooting, cops on stairs, and people in hall across from them. It’s at an angle, and closer to the door than Taylor’s vid.
I don’t recall the link; I had been downloading from twttr before anything got pulled.
