At the end of lunch period, earlier this year, my school went on lockdown. Someone being chased by police had run into the school. We waited in whatever classroom we were closest to at the time of the lockdown for about 20 minutes while the police searched the school, then it was declared that the man was not inside the school. 20 minutes after that, we went back into lockdown, when it was discovered he was still in the school. He had been hiding behind a curtain (Yes, really) inside the dance studio. You know, one of those gigantic curtains. Well we had to stay on lockdown until they caught him, even though he was seen leaving school grounds a bit after that. It took them about 90 minutes to find him. They found him rolled up in insulation on someone's porch. He was evidently very original in his hiding spots.
