The Acid Test

The show begins with finding that guy from a big audience of people who are volunteering, and ends with him in a situation which he doesn't know is being filmed. And will he do it? Will e, in that situation, fire a gun which he believes is real, at somebody and seemingly shoot them? But there was this really interesting bit at the beginning - we had no idea for he was going to do it or not. The other thing that surprises me is, again, if it's just sort of a playing along, is behaviours that people wouldn't know to do, that get shared across, say, an audience. Very often.
