A bill that passed the Illinois Legislature requires school principals to report bullying to parents within 24 hours. Some opponents say that is not feasible. “I could come up with 20 different scenarios where that doesn’t happen in 24 hours,” said Mark Klaisner, president of the Illinois Association of Regional Superintendents of Schools.

Bullying, fighting, and medical emergencies are much more common than school shootings. But many leaders will focus on the most extreme incidents when developing a safety plan.
