Maybe they should install some metal detector in front of the school entrance. There should be a possibility of copycat thingy. Nowadays strawberries snowflakes, mentally very brittle one.

Parents today themselves are also full of problems how to bring up and discipline their kids.

if really want to bring in weapon, just throw it over the wall/fence, den enter school and go pick back can leow.

Some new school walls are quite tall, can't throw over. Also, install CCTV and motion detector.
