You might think differently if you were responsible for those children. Do you want to take the risk that it might be a real threat? How do you tell the difference between a real threat and one that isn&#x27;t real? I&#x27;m guessing the people at the school district thought the small risk wasn&#x27;t worth it, and decided to close the schools. Who would want to be labelled as the person who didn&#x27;t close the schools if someone ended up getting killed? Even if the threat seems implausible, it must be a very difficult decision to make. There have been many bomb threats recently, probably mostly implausible, but for every one of them the airline acts as if it might be a real threat.
