Newly released surveillance camera footage from inside the Robb Elementary School in Uvalde, Texas, has shed new light on the police response to last month’s mass shooting at the school that killed 19 fourth graders and two of their teachers. New video shows heavily armed officers were inside the school and had at least one ballistic shield just minutes after the gunman entered the school. But officers didn’t enter the classroom for another 58 minutes. It has also emerged that a Uvalde police officer had a chance to shoot the gunman before he entered the school, but the officer declined to take the shot, fearing he could accidentally hit someone else.
