The UCPD released a statement yesterday afternoon, in which spokeswoman Nancy Greenstein explained: "This is a longstanding library policy to ensure the safety of students during the late-night hours. The CSO [community service officer] made an announcement that he would be checking for university identification. When a person, who was later identified as ... Tabatabainejad, refused to provide any identification, the CSO told him that if he refused to do so, he would have to leave the library.
I guess he didn't move fast enough...
After watching the video I don't think they are upholding there policy.. looks to me to be pretty dangerous to go to the library late night at UCLA..
