Vandals staged attacks early Wednesday on the buildings used by the Reserve Officers Training Corps at N.C. State University and UNC-Chapel Hill, echoing similar assaults on three Triangle recruiting stations last month. As before, vandals sprayed anti-war slogans and profanity, splashed red paint and claimed responsibility with a mass e-mail message to area media outlets. Lt. Col. Carol Ann Redfield of the Army ROTC program at N.C. State was caught off guard. This is the first time I know of that anything like this has happened here, she said. I certainly appreciate that people have different opinions, and they should be able to express them, but I have a problem when they damage property. The e-mail, from someone calling himself celest ialbeing said, Stop these recruitment centers that target poor people and people of color to fight to maintain the power structure that (literally and figuratively) imprisons us daily. The vandals sprayed slogans at the base of an entrance to Reynolds Coliseum, which holds the Department of Military Science, and tossed paint onto an ROTC sign above the entrance. Investigators had good leads, said Sgt. Jon Barnwell of the N.C. State Police Department. At UNC-Chapel Hill, campus police spokesman Randy Young said investigators were aware of the e-mail and the link with the attack at N.C. State. Were certainly looking into that, he said. Investigators think the UNC Naval Armory was attacked between 4 and 5:30 a.m.
