It shouldn't be a federal case, but it is. Why? Because some of my colleagues in education appear unable to digest the basic lesson of Tinker v. DesMoines and subsequent decisions on the rights of students while at school.

Amber Mangum was a frequent reader during lunch breaks at her Prince George's County middle school, silently soaking up the adventures of Harry Potter and other tales in the spare minutes before afternoon classes. The habit was never viewed as a problem -- not, a lawsuit alleges, until the book she was reading was the Bible.

A vice principal at Dwight D. Eisenhower Middle School in Laurel last month ordered Amber, then 12, to stop reading the Bible or face punishment, according to a lawsuit filed Friday by Amber's mother. The lawsuit, filed in U.S. District Court in Greenbelt, alleges that the vice principal's actions violated the girl's civil rights.

"Amber's a new Christian, and she's trying to learn all she can," said Maryann Mangum, the girl's mother. "She reads her Bible and she goes to Sunday school. . . . It really upset me when she was not allowed to read it on her own time."

John White, a spokesman for the school system, said administrators learned of the lawsuit Friday and were not prepared to comment on its claims. "We're just beginning to look into it," he said.

Mangum said her daughter was reading her Bible on Sept. 14 when Vice Principal Jeanetta Rainey approached. According to Mangum and the lawsuit, Rainey told Amber that reading the Bible violated school policy and that she would face discipline if she continued to do so.

Later that day, Amber recounted the episode to Mangum, who is her adoptive mother and also her biological grandmother. James Baker, a family friend, sent a note to the school asking that the principal identify any policy barring students from reading the Bible during their free time.

The note quoted a section of the school system's administrative procedures, saying that students "may read their Bibles or other scriptures, say grace before meals, and pray before tests to the same extent they may engage in comparable, non-disruptive activities."

In other words, not only did the administrator ignore the constitutional rights of Amber Mangum, this administrator also ignored written district policy. And when the family challenged that misconduct, the school's principal decided to send teh complaint down the memory hole and ignore it.

No one is asking for special rights here. All that is being sought is equal rights. And if students may read the book of their choice during non-instructional time, the religious content of their choice cannot legitimately be used to thwart their choice of literature.
