For the third time since the end of March, an emergency notice alerted members of the Washington University community Wednesday about the presence of a weapon on University property. But while the previous two alerts notified about developing situations on the North and Medical Campuses, Wednesday’s concerned the Danforth Campus, home to all undergraduates and the majority of graduate students.

Though Washington University administrators have experience in planning security measures for past presidential debates, securing the campus for tonight’s vice presidential debate tonight was no easy task.
