I just got an email from our friend Mike Daisey. Turns out, by coincidence, that they were taping the show the night of the walk-out. Above, you can see what happened -- apparently they were objecting to the word "fuck" being said in front of high-school students? Hard to tell, because none of them will talk to Mike as they file out of the theater.
In the video above, you can see not only the walk-out, but Mike's perplexity, then anger, then regrouping. As a special bonus, you can see a bit of Mike's great show.
Note to protesters: this was a shitty protest.
