When a train carrying toxic chemicals derailed in a small town in eastern Ohio on February 3, reports soon appeared in national news outlets. They showed how a fire followed the wreck, with ominous dark smoke clouds billowing over the town of East Palestine. Officials evacuated the region and began what they called a controlled release of chemicals from the train cars. But the disaster, in a town of fewer than 5,000 people, didn’t dominate mainstream news coverage.
