This happened at UCI????

My niece is a freshman at University of California, Irvine and is staying in the dorms there. This weekend there was an armed robbery at her dorm. 3 guys broke in and tied up two students and took all their stuff (cell phones, etc, probably left the test books). The police have not caught the guys. One of the victims had lost his key to the dorm and police think that is how they got in. Only stuff was taken and no one was hurt, so it is a recoverable incident. However, how will these kids be able to protect themselves? The police (city and campus) can't be everywhere at all times. My niece is a little frightened (as are her parents), but she will be going back today (Monday is a holiday).
