Atlanta's indymedia site has background but does not yet have news of the protest:
AP has a story about the protest before Bush arrived:
Beating drums and chanting, "In 2004, Bush no more," about 300 people marched in circles near the tomb, saying the president's stop there was merely a "photo op." Some protesters held signs that displayed King's image and read, "War is not the answer."
The Atlanta Constitution has a good story about the protesters perspective:
About 3:45 p.m., the president will lay a wreath at the late civil rights leader's crypt at the Martin Luther King Jr. National Historic Site. The president announced his visit on Friday.
But the MLK March Committee, a group of area civil rights activists who worked with King, say they have worked for months on a program to honor the civil rights leader at Ebenezer Baptist Church, across the street.
"They told us that the Secret Service wanted us out of there by 2 p.m.," said the Rev. James Orange. "We are not leaving the church." The Ebenezer program from 9 a.m. until 4 p.m. focuses on human rights.
