College students run under nearly 3,000 American flags lining the lawn of Pepperdine University in memory of those killed in the Sept. 11, 2001, terrorist attacks 12 years ago, at the corner of Pacific Coast Highway and Malibu Canyon Road in Malibu, Calif., Wednesday. Those who died in the attacks who were not from the United States are memorialized with a flag from their home country. (AP Photo/Damian Dovarganes)
