Each attempt to enter a restricted area was noted immediately through the access control system monitored by the Harvard University Police (HUP). HUP officers monitored the events and moved quickly on yet another failed entry attempt. The person responsible was apprehended and the card confiscated.
All students, faculty, staff and alumni are expected to carry university-issued photo identification badges. In addition to allowing access to appropriate buildings, the cards also are used for library, food services, recreational and various other purposes.
