Texas state police will not discipline any more of its officers over the Uvalde school shooting that left 19 children and two teachers dead as heavily armed agents hesitated to confront the lone gunman, a spokesperson confirmed Friday.

The decision is a turning point nearly nine months after one of the worst school attacks in U.S. history, and the widespread outrage over the officers who allowed more than 70 minutes to go by before stopping the massacre.

It also raises new questions about how many of the nearly 400 law enforcement personnel who were at Robb Elementary School last May might face discipline. They came from a constellation of agencies in South Texas, including the Texas Department of Public Safety, U.S. Border Patrol and local police. Two DPS officers have been fired, and one of them is appealing his termination.
