Outside the Courtyard Marriott in Shadyside, police deployed smoke bombs in the absence of protest activity, forcing bystanders and hotel residents to flee the area.
Later, while some protests were ending, riot-clad officers surrounded an area at the University of Pittsburgh, creating an ominous spectacle that some described as akin to Kent State. Guild legal observers witnessed police chasing and arresting many uninvolved students.
