I was there on Saturday night heading east from the southernmost point of the food area, walking by the porta-potties, when a stampede of terrified people crossed our path--they were definitely running north, away from something scary; I assumed a gun. My friends and I continued east after the mob had passed [...] 20-30 police in riot gear appeared on our left, broke off into formation, and started charging north, as did a bunch of blue lighted vehicles of some kind, which were closer to the lake shore.
