How dangerous air bags can find their way into used cars

A Nevada crash that nearly killed a young woman has exposed a hole in the government's efforts to get dangerous Takata air bag inflators off the road: There's nothing that prevents the devices from being taken from wrecked cars and reused.

Karina Dorado's trachea was punctured by shrapnel from an inflator in an otherwise minor crash in Las Vegas on March 3. She was rushed to a trauma center, where surgeons removed pieces that damaged her vocal cords. She is still being treated for neck injuries.
