Locked bathrooms are giving students at Mt Diablo High School a valid reason for fidgeting in...

CONCORD -- Instead of beating the bell between classes at Mt. Diablo High, senior Charles Campos often finds himself waiting frantically for a chance to use a rare unlocked restroom on the sprawling campus.

Relief has been hard to come by since embattled Principal Kate McClatchy closed all but one boys' and girls' bathroom to the 1,400 students last year. Although McClatchy unlocked a second set of restrooms this week, the dearth of commodes may violate the state's education code. She refused to say why she did it, but district trustee Gary Eberhart said he's been told it's because of graffiti.
