This was not “training” or a “fire drill”... this was an admitted “prank” from the start that went way over the line. Only after the damage has been done are some calling it a “learning experience”.
I suspect you are right about this being merely a prank. My argument assumes that it was drill and questions why some so readily dismiss the idea as being foolish and further the ranting that our kids can’t handle five minutes of fear in a controlled setting.
Even if it was a prank, we should teach children to laugh it off. Instead we are teaching children to have no humor because the weakest links might be traumatized by a five minute joke. The feminization of America is now giving way to the Wussification of America.
