They could write about anything they wanted, said Dewey Christian. But when Marshall Williams turned in a report on attending a gun show in Fort Worth, Christian said he was giving him a zero because of the topic. A spokesman for the school district told local media that, after the boy's mother complained, the teacher accepted the paper and apologized to Williams.
