lol.... Guy walks in with a ball cap and red backpack on around 2:56. Watches for a second, jumps in, sinks the choke, holds it till the guy passes out, lets go, sticks around for a second then exits stage left. I like that guy....
He was an unsung hero that day. That was pretty badass the way he choked that guy out and then he casually walks away because he's got other things to do.
It's a big place. Odds are someone else needed choked.
