"Peace Mom, Cindy Sheehan was one of those arrested. According to the press release of the sponsoring groups the action was carried out in order to focus attention on ending the U.S. war in Afghanistan and the U.S. occupation of Iraq; stopping the U.S. drone bombings in Pakistan; and to demand the closing, as a moral and legal issue, of the Gitmo and Bagram prisons. The activists also want the culpable members of the Bush-Cheney Gang brought to the Bar of Justice for their role in sanctioning and carrying out the illegal policy of torture.
