Donning orange jumpsuits and black hoods, Occupy DC and Amnesty International protesters marched on the Supreme Court Wednesday and on the 10th anniversary of the opening of the Guantanamo Bay prison called on federal authorities to shut the facility down. About 500 people participated in the march, which kicked off with a rally outside the White House and concluded at the Supreme Court with rows of jumpsuited protesters standing in line, heads bowed, evoking images of suspected terrorists detained at the U.S. base in Cuba.

Speakers called on President Obama to close Guantanamo, charge the terrorism suspects detained there and release those who have been cleared to return home to their native countries.
