Food Fighting Students Arrested??

Found this article via LRC (as I find most of my "news"), and could hardly belive what I was reading. Why on earth would anyone even think that arresting kids for participating in a food fight would be a good idea?? I mean, sure, there are a battery of "school punishments" available, the old detention, no recess (or whatever the trend is in middle school... I was a homeschooler from 6th grade on), lines, notes to parents, parent-teacher conferences, have them clean the mess (not really a punishment per se, but if I had thrown food on the walls at home as a kid that would surely have been included), whatever... but ARREST THEM?? For Pete's sake, they're kids, and they were throwing food. I'll quit ranting now...
