Y’all (the audience, obviously not you in particular) must’ve done something to piss the band off. When I went to see them (and this is well attested to at other shows on their last two tours), they definitely stood around taking pictures of the audience (Tony Levin is also really into photography), with Fripp walking off last. Having said that, Fripp saw someone behind me trying to take a picture during Schizoid Man and stopped playing, shook his head, and wagged his finger until he put the camera away.
