WASHINGTON -- Waving anti-war signs, thousands of protesters yesterday loudly booed and shouted "Shame on you!" at President Bush as his limousine drove down Pennsylvania Avenue to open the 55th inaugural parade.

Bush's motorcade sped up as it drew close to John Marshall Park where demonstrators had been permitted to gather, surrounded by security forces.

Some of the protesters threw bits of garbage and tossed crumbled paper at the motorcade, which was protected by two rows of police officers. Other protesters turned their backs as Bush rode by; some used tape to spell words such as "liar" on the backs of their coats.

Earlier, protesters had attempted to disrupt Bush's inaugural address at the U.S. Capitol. Chanting anti-war slogans and carrying coffin-shaped cardboard boxes to symbolize the deaths of U.S. troops in Iraq, they could be heard as Bush wound up his inaugural speech.

Bush gave only a slight indication that he heard the protesters, finishing his speech without interruption. Michael Lauer, a spokesman for the U.S. Capitol Police, said five people were arrested during Bush's address.

There were scattered protests in other parts of the nation's capital, as well. Three blocks from the White House, demonstrators attempted to rush a security gate and burned a flag. Police responded quickly, locking down the area and using pepper spray, briefly trapping nearly 500 spectators in a security checkpoint.

In the morning, about 500 people rallied at Malcolm X Park several miles from the Capitol, then marched down 16th Street to McPherson Square, the closest they were allowed to get to the White House.

Demonstrations were loosely organized by an anti-war group, International ANSWER (Act Now to Stop War and End Racism), but covered a range of issues, including support for gay marriage, opposition to U.S. policies in the Middle East and support for the Green Party.

The main issue for most protesters at John Marshall Park was the war in Iraq. Many carried homemade signs with slogans such as "War Is Not a Moral Value, "Who Would Jesus Bomb?" and "Thousands Dead in Iraq, Yet Bush Says He Is Pro-Life."

Most who spoke to the protesters from a reviewing stand offered harsh criticisms of the war, leading chants such as "Save America, Save Iraq. Make Texas Take Bush Back."

Katie Johnson, a recent college graduate, and her father Michael traveled from Wilmington, Del., to unfurl a lengthy banner that read: "Who made torture an American value?" In one corner, the banner had a picture of a yellow ribbon emblazoned with the words, "Support Our Troops. End the War."

"I just think this is something we should all do -- protest the war," said Katie Johnson.

John Cochran took his 5-year-old daughter Martin Lane out of kindergarten to demonstrate at the park. Martin passed out tiny homemade buttons reading, "Who will speak for the common good?"

To get to the park, many demonstrators spent several hours mingling with Bush supporters in long lines at the glacially slow security checkpoints. Protesters with Mohawks jostled next to Bush supporters in fur coats, but the mood remained generally polite.

Abandoned backpacks piled up at the checkpoint because no one was allowed to take in a bag bigger than 6 inches by 8 inches. Security officers patted down each person, with separate lines for men and women.

Denise Ramsey and her son Trey, a second-grader sporting a "W For President" cap, were among the Bush supporters standing in the security line.

"Bush won, so this protest doesn't bother me," said Denise Ramsey, who lives in Vienna, Va.

Linda Nemia of Binghamton, N.Y. also was there with her son, Justin, 15. She traveled to Washington because her son wanted to be part of the inaugural demonstrations against the war in Iraq. Although she supported the cause, as well, Nemia's ankle-length fur coat drew some negative comment from other demonstrators, which she took good-naturedly.

"I just want to be warm," Nemia said, laughing.

After Bush's motorcade passed by, the protesters began to leave, uninterested in watching the military bands and floats in the parade. As they gathered their signs, however, Peyta Lindsay, a spokeswoman for the anti-war group ANSWER (Act Now to Stop War and End Racism), told the group that their task was just beginning, and she urged them to attend a March 19 anti-war rally in Washington.

"We have made our mark today. The whole world is watching," Lindsay said.
