Texas authorities on Friday outlined a series of stunning new developments in the investigation into the school shooting in Uvalde, Texas that left 19 children and two teachers dead earlier this week, including acknowledgments from authorities that police were too slow to confront the gunman. 

The intense news conference Friday addressed many of the contradictory remarks made by police over the days since the shooting at Robb Elementary School on Tuesday. It also spurred new questions about law enforcement’s response to the attack and why officers stood in a hallway outside a classroom where the shooter was holed up for more than 45 minutes as gunfire sporadically rang out and children called 911 for help. 

“From the benefit of hindsight, where I’m sitting now, of course it was not the right decision. It was the wrong decision. Period. There’s no excuse for that,” said Steven McCraw, director of the Texas Department of Public Safety.
