Nike's long-awaited release of a retro Air Jordan sneaker prompted mayhem at malls across the country just two days before Christmas. People lined up for hours Friday morning for the $180 Air Jordan XI Retro "Conord," based on a design that first went on sale in 1995. But some stores were given as few as 12 shoes, which means many customers were left empty-handed -- and angry. In Seattle, police used pepper spray on about 20 customers at the Westfield Southcenter mall, where more than 1,000 people lined up to buy the shoe at four stores. In Lithonia, Georgia, four people were arrested after breaking down a door trying to get into a store early.
