That’s a good youtube vid capture. The guy dropped dead about 5 feet from the door. Wow. At 10 seconds in, you can see he fired his gun at the guard
Notice how quickly the staff takes cover - the perp isn’t even through the first set of doors and already the tellers are hitting the floor. I wonder if the moron was announcing his intentions as he charged in - it that’s the case, he probably signed his own death warrant, as it gave the old guy enough lead time to draw and take aim.
