Several hundred protesters, mostly college students, rallied against a potential war with Iraq and police tactics in the post-Sept. 11 era outside the Justice Department Sunday in a much smaller demonstration than the one staged the previous day.

Sunday's demonstrators again decried the possible war, waving a U.S. flag with a peace symbol instead of stars in the field of blue.

The group then went on a mile-long trek to the White House.

"Bush is asking for a weapons inspection everywhere else and it's only fair that his place is inspected too," said Jodi Hiland, 32, of Minneapolis.

Rally organizers told protesters to cluster at the front if they wanted to get arrested, setting a more confrontational tone than was seen at the Saturday demonstration -- when only a few people were taken into custody.

Police cleared the way for the march, with several vehicles at the front of the procession.

The demonstrators, stationed between the Justice and FBI buildings, expressed outrage over what they see as overreaching law enforcement tactics since Sept. 11, 2001.

"This is the center of all the racist attacks on people of color that have been happening for so long," said Peta Lindsay, an 18-year-old freshman at Howard University.

Shouting from a megaphone, Lindsay told the crowd that the FBI and Immigration and Naturalization Service are going to universities and demanding files on certain students.

"We will defend ourselves and our brothers from these racist witch hunts," Lindsay said.
