I think I need to slow this down a bit to watch the techniques. My roomate had several black belts in Aikido back in the day. I was dumb enough to fall for the "Hey Anson, try & punch me" trick a few times.

There was never any hard strikes, just a lot of shifting the enemy's balance and movement.
Watch the middle when the gun gets pulled on him.
