In this case defense against boredom led to an assalt on a teacher. An iPod confiscation led two kids to beat up a teacher right inside the school and break his neck:
Teacher Injured By Students Over Confiscated iPod
(CBS 3) PHILADELPHIA A popular Germantown High School teacher suffered a broken neck Friday during a scuffle with students over a prohibited electronic device.
The alleged incident happened just before noon after math teacher Frank Burd confiscated an iPod from a 11th grade member of his class.
Following class, authorities said the 17-year-old student and a 15-year-old freshman then assaulted the teacher in the hallway, knocking him to the ground.
"One student pushed the teacher, the teacher fell over, he suffered a gash on his face and broke two bones in his neck," said Paul Vallas, School District of Philadelphia CEO.
