What If You Can't Walk Away?

I would have to assume the abuser was well aware of my presence and that his behavior would cause a fear reaction in bystanders confined with it -- and that he didn't care.

In close quarters like that, I doubt the contention that it was all a gag would cause me to let my guard down after it had been so menacingly forced up. I don't think I'd be inclined to look up just because the guy pointed and told me there was a camera, and with his "victim" joining in, I'd have to consider her an accomplice and wonder what kind of further deception I was being set up for.

In other words, this is a profoundly stupid and irresponsible "experiment." Try it around the wrong (right?) person, and someone is going to get hurt.
