They say when all you have is a hammer, everything looks like a nail. Likewise, when you call the cops to a middle school cafeteria food fight, they will take 25 kids to jail. It's what they do!
Who's to say that flying milk carton is not full of kerosene? Go, NYT:
Diana Shulla-Cose, president and co-founder of Perspectives Charter Schools, said that an on-campus police officer had called for backup as the food fight escalated and that the resulting heavy police presence had led in turn to the large number of arrests.
Any time you're in need of assistance, call the police, and they will arrest somebody, for something, or, failing that, arrest you.
UPDATE: The PR person from Perspectives Charter School sent us a lengthy statement on this, which can be summarized as "The event is not reflective of the culture of our school." Duly noted.
