Texas shooting: Police waited 45 min in school before pursuing shooter

Nearly 20 officers stood for about 45 minutes in the hallway outside the adjoining Texas classrooms where the gunman killed students and teachers this week before US Border Patrol agents unlocked the door to confront and kill him, authorities said Friday. At least some of the 911 calls made during the Tuesday attack on Robb Elementary School in Uvalde came from inside the connected classrooms where 18-year-old Salvador Ramos was holed up.
