Cindy Sheehan and other anti-war activists are rallying Saturday outside CIA headquarters in Langley, Virginia, to protest the American use of drone aircraft to attack al-Qaida and Taliban targets in Pakistan and Afghanistan. Former congresswoman Cynthia McKinney is also among the group that plans to march to former Vice President Dick Cheney's nearby home in McLean. Ms. Sheehan, now a celebrity, says plans call for staying on the sidewalks and public roads near Cheney's home. But she says some protesters may risk arrest by walking up to the house. Ms. Sheehan's 21-year-old son, Casey, was killed in the war in Iraq.
