The disclosure Friday that police in Texas stood by for more than 40 minutes while a gunman continued shooting in a Uvalde schoolroom came after two days of inaccurate and incomplete statements from the governor and the state’s top law officer.

Steve McCraw, director of the Texas Department of Public Safety, acknowledged during a news conference that commanders at Robb School chose not to storm the classroom even as the shooter continued firing, and as students were on the phone with 911 operators pleading for police protection.

The gut-wrenching revelation came three days after 19 students and two teachers were gunned down, and at least 17 others were wounded. 

During the days between, McCraw, Gov. Greg Abbott and other officials offered a very different narrative. 

Among them: McCraw and Abbott repeatedly claimed the teenage rifleman was confronted by a school police officer before entering the classroom, and violence began with an exchange of gunfire between the two. 

McCraw initially said after the gunman crashed a truck next to the Robb School campus, the officer went to investigate and saw the 18-year-old with a rifle. “So he followed him right in immediately when rounds were exchanged.” 

That depiction was Wednesday. Within 24 hours, another top lawman announced that the account was wrong: There was no initial shootout. No school police officer even engaged the gunman, who simply walked in. 

“It was first reported that a school district police officer confronted the suspect as he was making entry. Not accurate,” said Victor Escalon, regional director for the Department of Public Safety. “He (the shooter) walked in unobstructed initially.”

In the aftermath of any massive, deadly event, facts can be tricky. Perceptions get distorted and rumors fly in what’s euphemistically referred to as the fog of war. 

The complete reversal of a key narrative fact was far from the only one. 

As the gunman massacred students and teachers, with at least 19 officers outside the doors and dozens more bivouacked outside, parents were pleading with police to do something. According to published accounts, at least one of those parents was handcuffed and another was pepper-sprayed and taken to the ground. Some of the interactions were captured in videos posted online.

Yet Gov. Greg Abbott and DPS Director Steve McCraw made no mention of those events during their initial news conference. Instead, they stressed the “quick response” of brave police officers who saved many children’s lives.Abbott himself suggested the narrative might shift when he spoke Wednesday, flanked by a range of top Texas officials. “Let me tell you the best information we have at this time,” he said. “Ongoing investigations often reveal new information as those investigations progress.” 

The information released over the next three days would indeed be new. In many ways, they would also directly contradict the officials’ own account, compounding a tragedy.

FRIDAY: Department of Public Safety Director Steven McCraw arrives to give a press conference in front of Robb Elementary School.

Speaking again Friday afternoon, Abbott said he was “misled” and “livid,” and that he had repeated the details that had been told to him Wednesday. He did not identify the officials that provided the information. 

The following reflects what Texas officials had divulged before Friday’s revelation that officers did not storm the classroom because an incident commander believed the gunman had finished killing students and there was, as McCraw put it Friday, “no risk to other children.” 

The speed of the response

Abbott, on Wednesday:

“The reality is, as horrible as what happened was, it could have been worse. The reason it wasn’t worse is because law enforcement officials did what they do. They showed amazing courage by running toward gunfire for the singular purpose of trying to save lives. And it is a fact that because of their quick response … they were able to save lives. Unfortunately, not enough.”
