As war protestors marched toward Arlington Memorial Bridge en route to the Pentagon yesterday, they were flanked by long lines of soldiers and others who stood in harmony with U.S. troops. Many booed loudly as the protesters passed. Some turned their backs to them or yelled, "If you don't like America, get out!" ----. Some of these protestors even spraypainted the pavement on a Capitol terrace. Others crowned the Lone Sailor statue with a pink headband.
