Uvalde police officers are being chastised once more after a newly released video shows them stopping for hand sanitizer and to check their phones while a school shooter was locked in a classroom.

A surveillance video from Uvalde’s Robb Elementary School, which was released on Tuesday, reignited outrage over the police department’s slow response to the May 24 massacre in the small Texas town. Families of those killed in the shooting, as well as others, have complained about a lack of transparency surrounding the multiple investigations into the massacre, which killed 19 children and two adults. Families, as well as state and local officials, have now condemned the video’s release.

According to CNN’s Shimon Prokupecz, Javier Cazares, whose daughter was killed in the shooting, reacted with outrage, as did other families.

“We were supposed to get some footage of the filming inside the hallway shown to us on Sunday, and then we got a call,” Cazares explained.

The previously unseen video, obtained by the Austin American-Statesman and KVUE, depicts the harrowing events as the 18-year-old gunman enters the school and walks toward a classroom with a long gun. Before the shots ring out, the video shows a student step around a corner and look at the gunman.

Police are still gathered and waiting in the hallway, according to school surveillance. One checks his phone for a moment. After more shots are fired, a group of officers moves toward the classroom but are denied entry. More officers arrive, and one in body armor pauses to dispense hand sanitizer from a dispenser. After more waiting, more heavily armed officers arrive and, in a burst of gunfire, confront the shooter.

Previously, Uvalde police were heavily chastised for their slow response to the shooting. According to previous reports, police did not have the keys to unlock the door where the shooter was hiding.

“The new surveillance footage of the Uvalde shooting breaks my fcking heart,” tweeted Twitter user @fuhknjo. “I couldn’t finish watching it. COPS STANDED THERE DOING NOTHING. My aunt and uncle did not deserve this… justice is required.”

“These cowards spent 77 minutes doing nothing while children were murdered,” writer Janice Dean tweeted.

“It’s crazy to watch this shooting footage in Uvalde and see responding officers doing literally nothing,” tweeted Twitter user @polishXcellence. “I was hoping for some nuance in the reports, but they are simply doing less than an average, untrained person would.”

Steven McCraw, the state’s Public Safety Director, issued a statement condemning the video’s release. He stated that it would have been preferable if the families had been given the opportunity to see it first, as planned by state Representative Dustin Burrows, who is leading a legislative investigation into the shooting.

Uvalde Mayor Don McLaughlin told Newsweek that “it is unbelievable that this video was posted as part of a news story with images and audio of the violence of this incident without consideration for the families involved.”

“I continue to stand by my statements that full transparency and consideration for the families is the priority in this incident,” he said.
