A report of a high school administrator shooting blanks in a school so students learn the sound of gunfire caught my attention last week.

My initial thought when hearing that Cary-Grove High School in Cary was planning to include that in a “Code Red” drill was: Why do students really need to recognize that sound? My second thought was: I’m glad enough of these high school students don’t have experience with gunfire that officials think this could be useful.

It’s an interesting concept, perhaps an overreaction to public shootings, but it’s not likely to harm anyone. The way Cary-Grove school officials structured the drill, no students actually saw a “shooter” or a gun.
