Sixty-nine elementary students from Scales Elementary School got quite a scare during a recent field trip to Fall Creek Falls. Their teachers told them that a gunman was on the loose in the area: As the students lay cowering on the floor, a man in a hooded sweatshirt pulled on a locked door, trying to get into the room. But here's the punchline -- it turned out that the threat was just a prank. And the pranksters were none other than the teachers, who were trying to make the kids think about what it would be like to be in a real situation like that. Two of the school employees responsible for the prank have now been suspended.

I can understand why it might be useful to stage a fake drill for an emergency such as a fire, but the logic of staging fake terror attacks escapes me. After all, what if someone were to fight back? Nevertheless, this is not the first time we've seen a situation like this. Back in August 2004 I posted about a fake terrorism drill that took place in a government office in Carter County, Tennessee, in which the local Emergency Management Director secretly arranged for armed intruders to burst into the office, fire shots in the air, and take hostages... prompting the workers to panic and run for cover.
