Now I guess there's the potential they weren't actually shouting that and it was dubbed, but it seemed credible based on many of the sources discussing it on twitter, some of whom were 1 degree separated from the source of the video.
Aside: there are so many landmines in me writing this that I don't know how to qualify my comments well enough to not be accused of something. Guess no one has to say to me "may you live in interesting times."
