On March 27, officers from the Metropolitan Nashville Police Department (MNPD) responded to calls of an active shooter at The Covenant School in Nashville, Tennessee, and neutralized the threat within 14 minutes.

MNPD’s response was a stark contrast to another elementary school shooting in May 2022 at Robb Elementary School in Uvalde, Texas.
