We have him contained – and I know this is horrible and I know it’s [what] our training tells us to do but – we have him contained, there’s probably going to be some deceased in there, but we don’t need any more from out here,” Arredondo said.He described a hallway full of smoke from gunfire and saw Lt. Javier Martinez of the Uvalde Police Department retreat after he was shot at through a classroom door.Records supplied to CNN by DPS show Arredondo took required active shooter training at least three times, including in the December before the massacre.It reminds officers “First responders to the active shooter scene will usually be required to place themselves in harm’s way and display uncommon acts of courage to save the innocent.” Even as Arredondo was calling for assault rifles, it is now known that there were officers with long guns at Robb by 11:40 a.m., at the other end of the hallway.In his only extensive public comments since then, he told The Texas Tribune: “I didn’t issue any orders … I called for assistance and asked for an extraction tool to open the door.” Arredondo’s interview with investigators less than 24 hours after the tragedy and footage from surveillance and body cameras show he gave plenty of direction."
