Another development on the Texas shooting in Uvalde was publicized on Wednesday, claiming that the gunman could have been stopped if a Uvalde officer and a supervisor had better communication.

According to The Texas Tribune, the report from Advanced Law Enforcement and Rapid Response Training Center at Texas State University in San Marcos revealed that a Uvalde police officer asked for a supervisor's permission to shoot the Texas gunman.

However, the supervisor did not hear the request or responded too late. ABC News noted that the said officer spotted the Texas gunman before he entered the school, but the shooter had the chance to enter Robb Elementary in Uvalde while waiting for the supervisor's response.

"[The] officer did not hear a response [on his radio] and turned to get confirmation from his supervisor. When he turned back to address the suspect, the suspect had already entered the west hall exterior door at 11:33:00," The assessment from the Texas State University said.

The assessment from the Texas State University also emphasized that a "reasonable officer" would conclude the use of deadly force is warranted based on the circumstances in the Texas shooting sites.

The report then referred to the Texas Penal Code which justifies an individual to use deadly force if necessary to prevent the commission of murder.

Texas Shooting Gunman Should Have Been Spotted at The Parking Lot - Report

The report from Texas State University also revealed that the first Uvalde officer who responded at the Texas school shooting site should have been able to see the suspect in the parking lot of Robb Elementary school if he has "driven more slowly."

The report noted that the police officer who first responded to the scene was driving at a "high rate of speed."

The report added that the officer approached by foot, then the Texas shooting gunman might have been spotted before entering the premises of the school.

The report also found flaws in how Robb Elementary School maintains the security of its building. The report underscored that propping the door open is a common practice in the school, but it can "create a situation that results in danger to students."

In addition, the report publicized on Wednesday emphasized that the teacher in the classroom did not check if the door was locked and does not have the appropriate equipment to lock the door even if it was checked.

Uvalde Police Under Fire After Death of Texas Shooting Victims

The report from Texas State University was publicized amid the scrutiny faced by the Uvalde police over their response to the Texas school shooting that killed several children and teachers.

Last month, a surveillance video showed that the police officers were already at the school, but they waited for at least 58 minutes before they entered the classroom where the gunman is located.

The Texas school shooting at Robb Elementary in Uvalde occurred when the gunman, Salvador Ramos, entered the site carrying an AR-15 rifle. Tactical officers killed Ramos during a shootout in the classroom after he went on a rampage in the school.

At least 19 children and two teachers were killed in the Texas school shooting tragedy in Uvalde.
