School Violence

Since the series of shootings at public schools a few weeks ago, the topic of safety at school has surged to the front of many politicians' talking points. But I wonder what goes through the mind of a person who would add to his platform the idea of having thick textbooks placed under desks to serve as shields.
I wish there was a permanent solution to this unfortunate problem. Unfortunately, I don't think one exists. There are certainly measures schools can take to protect their students, but unless schools run students through the screening process of T.S.A., it is unlikely we fully protect our students.
