Going public with a desire to have the world's most wanted terrorist kill your math teacher will definitely add up to some serious trouble.

WMUR reports Rundlett Middle School, in Concord, New Hampshire, suspended a 13-year-old girl after she posted a message on her Facebook page saying she wished Osama bin Laden killed her math teacher.

The girl's mother, Kimberly Dell'Isola, said she agrees the message was in poor taste, but the school shouldn't have taken action, explaining, "You are denying her an education based on something she did at home. That's my business, not your business."

The girl has served her suspension, but she has yet to return to class because she's afraid of seeing the math teacher in question. Her mother has requested she be taken out of the class and receive instruction from a private tutor.
