Schools across the U.S. have been rocked by a spate of false threats of violence in recent weeks, forcing them to evacuate or temporarily close. Why it matters: Threats of bombs, shooters and other dangers disrupt learning and stir community-wide anxiety about school safety.

A 10-year-old student has been charged with felony terrorist threat for allegedly threatening to commit a school shooting at a Kerrville, Texas, middle school, police said Monday.

Family members of the 11-year-old boy who was arrested and perp walked after school-threat charge have had numerous brushes with the law.
