My kid has questions I can't answer. He wants to know how he's supposed to go to school and feel safe. I have no answers. I can't tell him that everything will be fine. I can't guarantee that. I can't lie. On the same day that a Florida teenager went into a high school and killed 17 people, my son's former PE teacher turned himself into the local police for child pornography and other related charges. Boom, crash, splat. He's 14. His sense of safety at school is shattered. How does he know that someone won't come onto the campus armed and determined to do damage? How does he know that he can trust the very adults he's been conditioned to rely on since pre-school? How do I answer those questions?
