, the school district's police chief, at the centre of the police response: giving orders, conveying and receiving information, and officers deferring to his position when confused over their roles or response to the shooting.
Arredondo has not spoken substantively to the public about his actions that day and he has declined CNN requests for comment. His lawyer, who has not responded to CNN requests for comment, told theArredondo told the House investigative committee that he did not "consider himself to have assumed incident command," according to the legislative report -- which quoted the chief as saying, "My approach and thought was responding as a police officer. And so I didn't title myself.
Arredondo remained in the hallway and provided updates to dispatchers, requested resources throughout the morning and early afternoon, directed the position of a sniper, gave an assignment to keep clearing rooms, made assignments when attempting to key into a neighbouring classroom and told a team of officers to "have at it" if they were ready to go.
Arredondo, who has nearly three decades of experience in law enforcement, has since been placed on unpaid leave, while the school board considers firing him. In addition, the city of Uvalde placed a police lieutenant, who was the city department's acting chief that day, on administrative leave while it determines whether he should have assumed command. It's not clear whether anyone else is on leave; city officials didn't respond to requests for comment.
Along the way, someone shouts at them from a building, Coronado shouts a warning to someone to be careful and pauses to share information with a dispatcher. While he's talking, they hear gunfire and begin running toward the building where the shooter is already inside a classroom. Coronado approaches the school on the same side as Arredondo and two other police officers.
Coronado -- the sergeant from a different agency who Arredondo said was "fully uniformed" in offering his testimony for leaving his radios behind -- retreats out the south door of the school and begins co-ordinating incoming resources. The information typically shared over radios isn't just useful to people speaking to each other. Any responding officer listening to their radio can use the information -- the facts, but also the cadence of their delivery, the tone of voice, the background noise -- to evaluate the situation and mentally prepare for what they're encountering. Dispatchers can also use that to co-ordinate resources from other agencies, even those outside law enforcement.
