Bomb Threat at school

Never a dull moment at the Hashiramoto Elementary School. The kids were all walked home today in groups after the 4th period due to a call the police received that there was a bomb planted somewhere on the school or nearby grounds. I do remember hearing several sirens in the neighborhood around 2:30 or so and wondered what they were. It turned out to be itazura denwa (prank call).

That's the 3rd time in a year that we've had some sort of violent threat to the school, the past 2 involving a knife-carrying man. But with the recent increase in violent crimes towards kids and schools, the police and teachers are taking nothing lightly. I wonder what we'd all do if one of the threats turned out to be real?
