Well, it is and has always been an open campus. Anyone can stroll around, and non-students sometimes do research at one of the campus libraries. Nonetheless, the fact that the perp was a wearing a student-style backpack would suggest that he likely is taking classes there.
well, that’s why I’m asking. The school says neither are students.
So, if you’re not a student, why walk around with a backpack, number one. And if you’re not a student, why cause a scene (that will potentially affect admissions or access), number two. Just strikes me as a bit odd.
