If schedule attendance is to be mandatory, then hardening them with manned walkthrough metal detectors will h armed guards is also mandatory. After all, it’s for the he children.
Unfortunately no matter how many metal detectors etc...these kids today want the limelight and a story. ..and they’ll create it for whatever reason their lamebrain minds can devise. We see it all the time with ridiculous selfies and videos they put out there.
Lets stop giving these kids the freedom and undeserved attention they demand would be a good start. The world does not march to their drummer and they haven’t figured that out.
