As she continues her anti-war protest, Cindy Sheehan is labeling President Bush a "maniac" and a "lying bastard," and she's vowing not to pay her federal income tax. "My son was killed in 2004. I am not paying my taxes for 2004," Sheehan told an audience of Veterans for Peace. "You killed my son, George Bush, and I don't owe you a penny. ... You give my son back and I'll pay my taxes. Come after me [for back taxes] and we'll put this war on trial."
