A Tennessee company could be heading for a legal battle with U.S. auto safety regulators after refusing a request to recall millions of potentially dangerous air bag inflators. The National Highway Traffic Safety Administration is demanding that ARC Automotive of Knoxville recall 67 million inflators because they could explode and hurl shrapnel.

The agency says at least two people have been killed in the U.S. and Canada, and six others have been hurt as a result of defective ARC inflators. The recall would cover about one-quarter of the vehicles now on U.S. roadways. In a letter posted late Friday, the agency told ARC that it has tentatively concluded a that the inflators have a safety defect. But ARC responded that no defect exists.

NEW YORK (AP) — For decades, a giant, inflatable rat with beady eyes, sharp teeth and a pustule-covered belly has been looming over union protests, drawing attention to construction sites or buildings with labor disputes.

Over the decades, Scabby the Rat has become an icon at the site of labor disputes and weathered multiple legal challenges. Now Scabby’s challenge is staying relevant in the age of new technology and social media. Scabby has a Facebook page, and QR codes that give people information about campaigns. But younger people often don’t always know what the rat symbolizes.

Although having a rat as a mascot seems quintessentially New York, Scabby the Rat was actually invented by a union in Chicago around the late 1980s (several claim credit).
