Nashville's School Safety Debate and Response.

Law enforcement tactics and training have evolved to confront the reality of repeated mass shootings at American schools. The swift response to the shooting at the Nashville school on Monday, in which three adults and three 9-year-old children were killed, highlighted a renewed focus on confronting the assailant as soon as possible, a longstanding priority underscored by the botched response to the elementary school shooting in Uvalde, Texas, last May. The shooting in Uvalde, one of the deadliest mass shootings at a primary or secondary school in the United States, had weighed on senior law enforcement officials in Nashville and other departments before the attack at the Covenant School as a reminder of what could go wrong.
