Replying to Bomb at my school today

Well lets start off, i live in pigeon forge tennessee and i go to pigeon forge high school, and at about 1:00 today there was a bomb threat at the middle school which is about 250 yards from my school, and a thing of smoke went off in a trash can and freaked everyone out, but it turns out that was just a distraction. So then they evacuated all the middle school kids to the high school, and then after they all went back we went into lock down, they atrted evacuating us at about 3:30 after 45 minutes of lockdown, and no one was allowed in to the building, and i finally got out a like 3:45 because of the traffic. And about 20 cop cars showed up and special op teams, and then a hazardous device bus with one of the robot bomb things, and i guess it went in and detonated the bomb, a friend told me the bomb was in a trash can . So i could have died at school, and whoever did this is screwed, and thank god for keeping me safe.
