A high school student caught and documented a teacher napping on the job.  So why is the student the one who's suspended?

FOX News Radio's Chris Hoenig reports:

The 9th-grader at Mustang Mid-High in Oklahoma snapped a picture of the substitute teacher snoozing during class.

(Student) "He fell asleep on the desk."

The student then posted the picture on Facebook, and a staff member saw the photo online.  The principal's decision for punishment?  Suspending the young photographer, angering fellow students.

(Student) "She got suspended just for putting a picture on Facebook.  And other people took pictures, but they didn't get in trouble."

District policy allows students to have cell phones on school grounds, but they can not use them during the school day.  In a statement, the District says they are investigating the teacher's behavior, and that student punishment is up to the principal's discretion.
