Justice Dept. To Review Law Enforcement Response To Uvalde Mass Shooting

The Justice Department announced Sunday that it will conduct a critical incident review of the response by law enforcement to the mass shooting in Uvalde, Texas.

The review, which is being undertaken at the rest of Uvalde Mayor Don McLaughlin, is tasked with providing "an independent account of law enforcement actions and responses that day, and to identify lessons learned and best practices to help first responders prepare for and respond to active shooter events," Justice Department spokesman Anthony Coley said in a statement.

Authorities in Texas spent three days providing often conflicting and incomplete information about the 90 minutes that elapsed between the time the gunman entered the school and when U.S. Border Patrol agents unlocked the classroom door and killed him. Law enforcement officers from local, state and federal entities responded to the Uvalde shooting.

Nearly 20 officers were standing in the hallway outside the classrooms during the attack on Robb Elementary School for over 45 minutes before agents used a master key to open a door and confront the gunman, Texas Department of Public Safety Director Steven McCraw said at a news conference Friday.

The on-site commander "was convinced at the time that there was no more threat to the children and that the subject was barricaded and that they had time to organize" to get into the classroom, McCraw said.

"Of course it was not the right decision. It was the wrong decision," McCraw told reporters.

Earlier Sunday, Rep. Val Demings, who was the Orlando police chief before she was elected to Congress, favored a federal investigation to determine what went wrong in the Uvalde response.

"Since there were so many agencies involved on the ground, it's important that we know what role every agency played," she told "Face the Nation" moderator Margaret Brennan. "It's important that we know, was there any discussion about going in, those 19 offices who we're told were in the hallway, were they any discussion between other commanders from other departments? We must know the answers to those questions. And I think a federal investigation is certainly in order."

Uvalde County Commissioner Ronald Garza welcomed the idea of a federal investigation when he was asked about it hours before it was announced. "I think we need to learn more. As tragic as this may seem, we need to learn from this, you know, and parents deserve answers," he told Brennan on "Face the Nation."

Once the Justice Department concludes the review, it will publish a report with its findings.
