Families of students killed in the Uvalde, Texas, school massacre are among those who could testify at the trial of a police officer who was part of the hesitant law enforcement response and is charged with failing to protect children from the teenage gunman.
Opening statements were set to begin Tuesday in what is a rare case of charges being brought against an officer who is accused of not doing more to save lives. Authorities waited more than an hour to confront the shooter.
