When students arrived, they were taken to the school gym, which had been sterilized, before being sent home.
Which had been sterilized?! How do you sterilize a gym, exactly? And do it in less then 2 hours, since the first teacher to report the birds came in a 6am, and I'm guessing some enterprising students showed up around 7:15. That's an impressive feat.
I remember senior pranks getting pretty crazy when I was in high school, but never did I hear of the school even considering closing over one of them. The last bit of overreaction? A court date is still being considered.
