SETAUKET - Anti-war protesters marked the eighth anniversary of the war in Iraq with what they call the "march of the dead" in Setauket today.As part of the march, dozens of people walked down Route 25A with white face masks signifying the thousands who have died in Iraq and Afghanistan. Many were holding signs with pictures of soldiers from Long Island who were killed."No one wants to lose people in service for our country for a war that need not be fought," says Chuck Perretti, of Setauket.The anti-war marchers were confronted by counter-protesters rallying across the street in support of the war. "I didn't march off to war in 1941 to give my country away in 2011," says World War II veteran Dominick Ercolano.President Barack Obama says at least 50,000 troops will remain in Iraq in support roles until the end of 2011.
