The Globe and Mail reports in its Saturday edition that a group of new and dangerous Grinches are threatening to steal Christmas this year. Globe columnist Gus Carlson writes that robbers have attacked delivery trucks, threatened drivers and stolen merchandise in several U.S. cities in the past few weeks, adding a new woe to retailers' growing lists of concerns as the holiday shopping season officially kicked off with Black Friday. Big store chains are already battered by losses from rising thefts by organized crime rings that have prompted store closings in many cities, and nervous about the spending power of inflation-scarred, recession-wary consumers. These delivery-truck attacks have exposed new vulnerability to all-important on-line sales, which depend on reliable delivery services. The industry can ill afford this lump of coal. Truck-jackers are bold, brazen and often armed. In a recent daylight robbery in Atlanta, a group of bandits ransacked an Amazon truck while the driver was making a delivery and fled with armloads of packages. In Sanford, Fla., a man jumped on an Amazon truck and threatened the driver. The financial impact will be real and customers will pay for it, regardless of where they live and shop.
