Superintendent Jorden Schiff says it started out as a prank. But as the eighth-graders began to get in trouble for taking up so much time, it turned into a protest about Thursday's shortened lunch period.
Schiff says the students were punished for holding up their peers and disrespecting lunch aides.
Schiff says some parents think a two-day detention went too far and others think it wasn't enough.
The school says it wants students to know they can express themselves without disrupting other people.
