Investigators question delayed police response in Texas school shooting

Investigators in Texas were seeking to determine on Saturday how critical mistakes were made in the response to the deadly Uvalde shooting, including why nearly 20 police officers remained outside a grade school classroom as children placed panicked 911 calls for help.

Why the officers waited in the hallway nearly an hour before entering and fatally shooting the gunman is at the heart of an ongoing probe by the Texas Department of Public Safety into the massacre of 19 children and two teachers in the deadliest US school shooting in nearly a decade.

Investigators are also still searching for a motive for the attack. Salvador Ramos, a high school dropout, had no criminal record and no history of mental illness.

At least two children placed 911 calls from a pair of adjoining fourth-grade classrooms after 18-year-old Ramos entered on Tuesday with an AR-15 semi-automatic rifle, Colonel Steven McCraw, director of the Texas Department of Public Safety, said earlier this week.

"He's in room 112," a girl whispered on the phone at 12:03 p.m., more than 45 minutes before a US Border Patrol-led tactical team stormed in at 12:51 p.m. and ended the siege at the Robb Elementary School in Uvalde, a town of 16,000 people west of San Antonio.

The same girl had implored the 911 operator to "please send the police now" at 12:43 p.m. and again four minutes later.

The on-site commander, the chief of the school district's police department, believed at the time that Ramos was barricaded inside and that children were no longer at immediate risk, giving officers time to prepare, McCraw said.

"From the benefit of hindsight where I'm sitting now, of course, it was not the right decision," McCraw said. "It was the wrong decision, period."

Standard law enforcement protocols call for police to confront an active school shooter without delay, rather than wait for backup or more firepower, a point McCraw acknowledged.

McCraw described other moments when Ramos might have been thwarted. A school officer, responding to calls about an armed man who crashed a car at the funeral home across the street, drove past Ramos as he crouched beside a vehicle on school property. Police have said Ramos fired at two people standing outside before scaling a fence onto school grounds.

The door that gave Ramos access to the building had been left propped open by a teacher, McCraw said, in violation of school district security policies.

As criticism of the response by law enforcement grew, police officers from cities as far away as Houston and Dallas began arriving in Uvalde to help support local authorities, in some cases providing protection to Uvalde's own police, the mayor and the gun shop where Ramos purchased his arsenal.

Police cruisers were parked outside the home of Pedro Arredondo, the school district's police chief. The police response to the shooting has been sharply criticized by McCraw and Texas Governor Gregg Abbott, among others.

Questions about police efforts to stop Ramos came as the United States' leading gun-rights advocacy group, the National Rifle Association, held its annual convention 275 miles (443 km) away in Houston.

Abbott, a Republican and staunch gun rights proponent who addressed the meeting in a pre-recorded video, seized on apparent police lapses in Uvalde, telling a news conference later he was misled and "livid about what happened."

Abbott denied newly enacted Texas gun laws, including a controversial measure removing licensing requirements for carrying a concealed weapon, had "any relevancy" to Tuesday's bloodshed. He suggested state lawmakers focus renewed attention on addressing mental illness.

President Joe Biden, a Democrat who has urged Congress to approve new gun restrictions, will visit Uvalde on Sunday to comfort families and pay respects to the young victims.
