Oh, sorry - maybe I wasn’t clear. That’s not what the video implied was going to happen, the audience always knew nobody was going to be hurt, and that the train was going to be stopped before it hit the workers. The episode shows how the “live” video feeds were actually recordings.

What was upsetting was that they made it seem like there was someone not in the know who thought they were actually having to make that choice, who didn’t know it was staged, which of course would be unethical.
