Damn lucky super.
They just showed the video right up until the guy was shot. The superintendent is an incredibly brave man. Several times he asks the shooter to let the others go.
You are also right, the super is incredibly lucky. Also some woman showed incredible spunk tho maybe a bit of foolishness as she comes up behind him and hits him. The shooter knocks her down but doesn’t harm her. Another brave woman comes partly up and asks if he will let her help the woman who is down. He never lets her but the woman finally gets up and gets away and the other woman follows her.
A really bunch of brave people.
