@SeddieLynnxxx Well,it's a North-American thing I guess, because I live in Canada. It's when someone or something dangerous such as a robber with a gun is in the area,and they lock down the school. The kids can not leave their classrooms, even if they need to use the bathroom or something. In my school,if a lock-down is real you need to shut off all the lights and hid in one area or under the desks! XP
