But there is some obvious lack of common sense in the sutuation. A security guard said they were hired to watch the event but not the building. But the event is located in the building! If someone, God forbid, decides to blow up something in the building, or shoot outside the event hall but hit the outgoing participants, it does become the hired security's responsibility, immediately! If you are hired to "stay in the door and watch those walking in and out", then someone from the company has to check the part outside the hall and definitely have a connection with the campus police, just for such cases. Otherwise it looks (and seems to be the case) that the external security company provides talking mannequins. Sorry.
