School Bomb Threats

So far this year my highschool has had 5 bomb threats. 2 in the beginning 2 last week and one today. Usually this would be real cool but this shit is getting so played now, they lock us down and dispatch dogs through the whole school and it blows because we just keep working in the same class for however long it takes to sweep the schol (about an hour) I don't think its a student because it's really hard to pull it off without getting caught. I think its someone trying to occupy the police while they are at my school to do something.
