‘More could have been done’: Texas police under scrutiny over response to school shooting

Gunman remained barricaded inside a classroom for up to an hour before his rampage was brought to an end

Texas law enforcement agencies are facing escalating criticism over their response to the mass shooting at Robb elementary school in Uvalde, after it emerged that the gunman remained locked inside a classroom for up to an hour while large numbers of police officers were amassed outside the room without taking any action.

At a press conference on Thursday afternoon, Texas authorities confirmed that the shooter had been locked inside a classroom for an hour before he was confronted and killed. He committed all his 21 murders inside that room - including 19 children and two teachers.
