...Another friend, Aaron Vire, 23, said Mr. Poplawski strongly opposed Democratic presidential nominee Barack Obama's candidacy. He'd had "very spirited debates" with Mr. Vire, who is black and an Obama supporter. "He wasn't a racist. He was a cool person. He thought he was losing some of his rights," said Mr. Vire. He said he knew Mr. Poplawski owned an AK-47 assault-type rifle, a .357 Magnum revolver, a .380-caliber handgun and a .45-caliber handgun.
