Over and over, every time the subject of pulling American troops out of Afghanistan has come up, U.S. Rep. C.W. Bill Young has voted to stay the course. He opposed resolutions to withdraw, and even a resolution to set a timetable for a full withdrawal. No longer. What changed his mind? A letter from 26-year-old Staff Sgt. Matthew S. Sitton. Young said Sitton predicted his own death, "and what he said would happen happened." He stepped on an improvised explosive device and was killed, leaving behind his wife, Sarah, and their 9-month-old son, Brodey.
