Around 6:20 pm tonight, a Public Safety officer shut down Zonker Harris Day before Twin Sister even got to play. The band had already set up all of their equipment, and had even started sound check, when the officer declared the event over, as it had gone past the reported ending time of 6:00 pm. When the officer, the students, and Twin Sister failed to reach any sort of compromise, the officer called his supervisor, who asserted again that the event was over. The students in charge of the event proposed moving it inside, to either the WestCo Cafe or the WestCo Lounge, but the officer was adamant that the event was terminated, and that it could not simply be moved to another location. He declared that if the band were to begin playing in the WestCo Cafe, Public Safety would shut it down immediately.
There will be more details added to this post as news arises.
