No, it couldn't have been. It's a mistake to believe that any prevention strategy will work on a large scale, and the reason is you'll always get too many false positives like that [1].
It's not just an issue with schools being too eager to report. It will happen in any scenario, including inside intelligence agencies if you force them to go after any "remotely potential terrorist". There will be thousands and thousands of false positives.
