A Texas House committee released a 77-page Sunday on the Uvalde school shooting, concluding that allowed an 18-year-old gunman to enter Robb Elementary School May 24 and kill 19 children and two teachers. The report, described as the most exhaustive account of the tragedy, cited a disorganized, chaotic law enforcement response crippled by an across-the-board leadership failure, multiple missed warning signs about the shooter’s propensity for deadly violence and a lax atmosphere toward security at the school that had developed over time.

Shortly after Texas news outlets published raw footage of the recent mass school shooting in Uvalde 鈥� and of police officers鈥� gut-wrenching delay in taking out the gunman 鈥� shady corners of the internet became a haven for new conspiracy theories. 

On 4Chan, the fringe chat board that鈥檚 notorious for hosting extremist content, users insisted the 82 minutes of school surveillance camera footage of the May 24 shooting, which resulted in the deaths of 19 children and two teachers, was staged. Rather than depicting one of the deadliest mass school shootings in U.S. history, forum users claimed the heavily armed officers seen milling about were either 鈥渃risis actors鈥� or simply participants in a harmless training exercise.

鈥淚 didn鈥檛 see anyone get shot,鈥� one user commented.

鈥淪aw a lot of police standing around during a live shooter training exercise though,” another said.

The footage jointly released by the Austin American-Statesman newspaper and KVUE TV briefly features the 18-year-old suspect as he walks unimpeded into the school and the piercing sounds of gunfire, but is mostly focused on police standing back in the brightly painted hallway. The news outlets chose to edit out the children鈥檚 screams and nobody is shown getting shot on frame, details that quickly became fodder for conspiracy theorists, including one who dubbed it propaganda promoting 鈥淒EMOCRAP GUNGRABBING.鈥�

Ever since news outlets released the footage this week inside Robb Elementary School, the small community west of San Antonio has endured a new round of trauma and turbulence. Anger once again focused on the failed police response, as the footage showed how officers with rifles and protective shields idled for more than an hour before confronting the killer, one casually sanitizing his hands from a wall dispenser.

 Yet for many, the publication itself became the focus of fury. 

While some experts saw the images as critical to holding police accountable, some Texas officials criticized the news outlets for their decision. Uvalde residents, particularly the victims鈥� families, said releasing the video publicly, before they were scheduled to see it privately first, was re-traumatizing. 

鈥淲ho in the hell do these people think they are?鈥� Angel Garza, whose daughter Amerie was killed, said on CNN. 鈥淵ou want to go ahead and air their final moments to the entire world. What makes you think that鈥檚 OK? The least you can do is have some freaking decency for us.鈥� 

Meanwhile, researchers who study school shootings and online extremism warned the footage would likely have intense preoccupation in fringe online communities, including those that advocate real-world violence. The video鈥檚 release has opened a debate about whether it serves any utility for the general public and has left some experts concerned that the footage could become useful for someone planning the next fatal attack. 

The Uvalde shooting 鈥渨ill have tremendous fascination for a certain segment of the population,鈥� said psychologist Peter Langman, who has spent decades . Time and again, his research has shown, perpetrators study and emulate the behaviors and tactics of previous gunmen. 

In , the Department of Homeland Security warned that online forums dedicated to the glorification of domestic extremist violence have been flooded with posts urging copycat attacks in the wake of Uvalde. Six of the nine deadliest mass shootings in the U.S. since 2018 , and federal law enforcement officials have warned that fringe online forums are being leveraged to radicalize young, violent extremists. Some have seized on the attack 鈥渢o spread disinformation and incite grievances, including claims it was a government-staged event meant to advance gun control measures,鈥� the threat bulletin warned. 

Violent videos are often presented online as memes or jokes and aren鈥檛 inherently harmful, said Kurt Braddock, an assistant professor of public communication at American University and a faculty fellow with the Polarization and Extremism Research and Innovation Lab. But such jokes, he said, can serve to radicalize. 

鈥淜ids and young people, they have a technological capacity that people who are older never had,鈥� he told 社区黑料. 鈥淭he problem is that they don鈥檛 have the media literacy skills to distinguish what鈥檚 a joke and what鈥檚 a call to action.鈥�

A compulsive interest with mass shootings in fringe online communities traces back to the 1999 Columbine High School attack in suburban Denver, which has been repeatedly cited by the shooters in subsequent attacks. In online communities, so-called 鈥淐olumbiners鈥� mull over every detail of the infamous shooting, sharing a vast photo and video archive of the high school gunmen. That includes haunting surveillance video footage from inside the school cafeteria. 

鈥淭here鈥檚 a whole phenomenon of Columbiners, people who are obsessed with every aspect of Columbine and track down every photo they can find of the perpetrators and post them on websites,鈥� said Langman. Because so many people were killed in Uvalde, he said a similar warped pursuit could emerge with the Texas massacre. Intellectual curiosity has driven some people to become obsessed with Columbine and subsequent attacks, Langman said, and others have developed romantic infatuations with the perpetrators. Meanwhile, he said a segment of the community is motivated by the desire for violence. 

 鈥淢ost of the people fascinated with these attacks are not aspiring killers but some of them are likely to be eventual killers and that鈥檚 where the potential danger is.鈥� 

鈥楾oo graphic鈥�

Surveillance video footage depicting the mayhem inside a school during a shooting is rarely released publicly. Beyond footage of the Columbine cafeteria, a limited selection of videos were made public after the 2018 mass school shooting in Parkland, Florida. But none were as extensive as the footage released in Uvalde, experts said. 

The video was published Tuesday by the Texas news outlets nearly a week before state Rep. Dustin Burrows, a Republican leading a legislative investigation into the shooting, had planned to show the video to victims鈥� families in a private screening before releasing it publicly alongside the probe鈥檚 preliminary findings. In a series of tweets on Tuesday, Burrows said he is 鈥済lad that a small portion is now available for the public,鈥� which deserves to see police officers鈥� response to the shooting, but expressed disappointment that victims鈥� families were unable to see it first. Meanwhile, efforts to withhold certain images and audio of the violence, he said, 鈥渨ere not achieved.鈥�

Uvalde Mayor Don McLaughlin , calling the media outlets鈥� decision to publish the video 鈥渙ne of the most chicken things I鈥檝e ever seen.鈥� 

In , the Austin newspaper explained that its decision came after 鈥渓ong and thoughtful discussions,鈥� and was done to provide clarity about what happened inside the school after weeks of confusion and repeated misinformation. The newspaper blurred the face of a student who appears momentarily at the beginning of the video and omitted the sounds of children screaming as the gunman entered their fourth grade classroom, a detail they deemed 鈥渢oo graphic.鈥� Editors ultimately chose, however, to show the face of the gunman as he entered the school undeterred.

鈥淥ur news organization guidelines state that we should not glorify these individuals and give them the notoriety that they seek,鈥� the paper said in the op-ed. 鈥淲e chose, in this instance, to show his face to chisel away at any conspiracy that we are hiding something.鈥� 

Such conspiracy theories had already become widespread in online forums, including 4Chan. In one online forum dedicated to mass shootings, users compared the Uvalde suspect to the perpetrator who carried out the 2012 attack on Sandy Hook Elementary School in Newtown, Connecticut, commenting on their physical and strategic similarities. The forum, whose previous users have included multiple mass shooters, including the Newtown gunman, was flooded with screenshots of the Uvalde suspect鈥檚 social media posts. 

Since the Columbine shooting, standard law enforcement procedures have called on officers to respond to threats immediately even at risk of their own lives, said campus security consultant Kenneth Trump, president of the Cleveland-based National School Safety and Security services. The hallway video from Uvalde, he said, is critical to hold police accountable for their hour-long delay before confronting the gunman. There鈥檇 be reason to withhold footage that depicts the gunman killing children, he wrote in an email, but not of officers in the hallway. That footage, he said, made clear that police lacked a coordinated response during the mayhem. 

鈥淭hat is fair game for public scrutiny especially given the conflicting accounts and finger pointing by public officials,鈥� Trump said. 鈥淭here are questions about accountability and you cannot have accountability without transparency.鈥�

Sen. Chris Murphy, a Democrat from Connecticut and a leading proponent of tighter gun control measures, also sees utility in the video. In an appearance Wednesday on MSNBC, Murphy said it clearly dispels a common right-wing talking point that 鈥渢he only way to stop a bad guy with a gun is good guys with a gun.鈥� 

鈥淚f one teenager with a high-powered weapon is so scary as to prevent all of those highly trained adults from going in and saving lives, maybe we should try to stop those teenagers from having those kinds of guns in the first place,鈥� Murphy said. 鈥淏ecause clearly, we never have enough good guys with guns. We can never have enough high-powered weapons in the hands of law enforcement to stop an assailant if we couldn’t get that job done given what we have seen on the tapes in Uvalde.鈥�

Yet for all its persuasive power, Murphy noted the traumatizing nature of the footage, saying 鈥淚 don’t recommend that people watch it.鈥�

A right to know? 

For years to come, the hallway video will serve as a mass-shooting training tool for police, said Jaclyn Schildkraut, an associate criminal justice professor at the State University of New York at Oswego. And given the intense scrutiny of the officers鈥� response, she said 鈥渢he only way to set the record straight is to release this video.鈥�

鈥淭he footage is so damning,鈥� she said. 鈥淵ou had officers sitting there on their phones, you had an officer who was not only on his phone but then went and sanitized his hands. It鈥檚 incredibly problematic.鈥�

Several officers can be seen checking their phones during the long standoff in the hallway, although a clarified that one who had come under particular attack was Uvalde school police Officer Ruben Ruiz, whose wife, Eva Mireles, had called her husband to tell him she had been shot inside the classroom. Mireles and her co-teacher, Irma Garcia, were both killed protecting their students.

Schildkraut said the video has limited value in the public domain, and could actually be harmful for the families of the victims who will be forced to relive the tragedy for the rest of their lives. They should have been given a say about the video鈥檚 public release, she argued, while noting the footage could fall into the wrong hands.聽

鈥淭here鈥檚 going to be people who come up with conspiracy theories and then go harass the families because that鈥檚 what they did in Sandy Hook and they鈥檝e done elsewhere,鈥� she said. 鈥淭his could end up on the dark web and people could idolize this individual even more. What public value does it add?鈥�

After the Sandy Hook shooting, conspiracy theorists flooded the internet with claims the tragedy was a 鈥渇alse flag.鈥� Last year, conspiracy theorist and InfoWars host Alex Jones in a defamation lawsuit by victims鈥� families for his repeated claims that the shooting was a hoax. 

A similar debate over the public鈥檚 right to know key details also followed the Columbine shooting, Langman said. Extensive footage has become publicly available, including the cafeteria surveillance video and other homemade videos created by the perpetrators. But some were never publicized, most notably the 鈥渂asement tapes,鈥� which reportedly included some four hours of film that offer a window into the motives and plans of the perpetrators just weeks before they carried out the attack. The tapes were due to concerns they could inspire more violence. 

American University鈥檚 Braddock said the Uvalde hallway video presents a catch-22. Transparency around the police response is important, he said, but it also offers a wealth of material to online circles of people with morbid curiosities or worse

鈥淚t鈥檚 so easy to turn the images from that video into memes that can circulate within these circles online, and those can serve to build other little communities of would-be mass shooters,鈥� he said.

The tragedy in Uvalde, Texas, which resulted in the deaths of at least 19 children and two teachers, unfolded just 10 days after the nation was shocked by a mass shooting that left 10 people dead at a supermarket in Buffalo, New York. 

It could be more than a coincidence: A growing body of research suggests these assaults have a tendency to spread like a viral disease. A research theory called the contagion effect suggests that mass shootings often happen in clusters, with intense media coverage playing a significant role in subsequent attacks. About a dozen studies, dating to the 1970s, suggest this is the case.

The U.S. has experienced 16 mass shootings in just 10 days, including the carnage in Buffalo and Uvalde. That鈥檚 according to , which tracks shootings that result in at least four injuries or deaths. So far this year, the U.S. has endured 212 mass shootings in which four or more people were shot or killed, according to the archive. 

The tragedy in Texas has reignited the country鈥檚 divisive and cyclical debate over gun laws, with President Joe Biden asking in an emotional White House address Tuesday night, 鈥淲hen in God鈥檚 name are we going to stand up to the gun lobby?鈥�

Jaclyn Schildkraut, an associate professor of criminal justice at the State University of New York Oswego, said shooters are often motivated by a desire for fame. She鈥檚 a proponent of the “, which urges media outlets to limit the frequency with which they publish a shooting suspect鈥檚 name and photograph.

Attackers 鈥渨ant people to know who they are, they want their name recognition, and so when we remove that incentive and we don鈥檛 report their names, we aren鈥檛 rewarding people for killing other people by making them celebrities,鈥� Schildkraut said. 鈥淚t鈥檚 also removing the incentive for other like-minded individuals who may be seeing the amount of coverage that a case is getting and want similar attention.鈥�

A day after the May 14 Buffalo supermarket assault, four people were killed and 23 were injured in five mass shootings: two in Texas, two in North Carolina and one in California. In one incident, a at a Taiwanese church in Laguna Woods, California, resulting in one death and five injuries. In another, two people were killed and three injured after in Houston. More recently, on Monday, in a shooting at a club in North Charleston, South Carolina. 

While the Buffalo and Uvalde suspects are both 18-year-old men, a motive for the Texas school shooting remains unknown, as does the degree to which the perpetrator studied or was inspired by the incident in upstate New York or elsewhere. But Adam Lankford, a criminology professor at the University of Alabama, noted that the Texas suspect was active on social media and reportedly outlined plans on Facebook prior to the attack. The suspect and communicated with a stranger online before the shooting, offering a cryptic message about what would soon unfold. Lankford said the suspect appeared to portray himself 鈥渁s a mysterious, dangerous man who might do something like this.鈥� 

鈥淗e was dancing around the possibility that seemed likely that he would do something dramatic, perhaps dangerous, and perhaps a mass shooting,鈥� Lankford said. 鈥淵ou can only dance around or imply that in a culture in which people are aware that young men with firearms too often do that.鈥�

The Uvalde shooting was the deadliest attack on a school since the 2012 mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, that killed 20 children and six educators. 

In one 2015 study on the contagion effect, researchers at Arizona State University found a in the immediate aftermath of a similar attack with four or more victims. A second incident was statistically more likely to occur within 13 days, on average, researchers found.

Yet a similar contagion effect doesn鈥檛 appear to exist in the wake of attacks with just a few victims, 鈥減ossibly indicating that the much higher frequency of such events compared with mass killings and school shootings reduces their relative sensationalism, and thus reduces their contagiousness,鈥� according to the researchers.  

So far this year, 27 shootings at K-12 schools have resulted in 67 injuries or deaths, according to , which has tracked such attacks since 2018. Prior to the shooting in Uvalde, the most recent campus attack unfolded just last week in Kentwood, Michigan. In that May 19 tragedy, after a Crossroads Alternative High School graduation ceremony.

In recent years, mass shootings in the U.S. have become 鈥渟ubstantially more deadly over time,鈥� by Lankford. Shooters often take inspiration from previous attacks and apply the lessons learned to their own. In fact, the number of mass shootings where eight or more people were killed since 2010, compared with the previous four decades.

The number of shooters who were inspired by previous attackers has also doubled, Lankford found. Between 1966 and 2009, a quarter of the deadliest shootings were perpetrated by someone who directly cited, referenced or studied a previous mass killer. Such direct influence was observed in half of the deadliest shootings between 2010 and 2019. 

Older attacks seem to have a stronger direct influence than more recent events, Lankford said. The Buffalo suspect, for example, reportedly referenced the 2019 mass shootings at two mosques in Christchurch, New Zealand, in writing. Lankford noted that mass shooters often conduct extensive research and planning before carrying out their attacks and are unlikely to act impulsively after learning about the most recent shooting on the news. Rather, at-risk individuals who have already been considering violence could see the latest headline and decide that now is the time to act. 

The rise of social media, Lankford said, has helped researchers understand how transmission occurs. 

鈥淲e鈥檙e increasingly able to study the social media and internet searches of the perpetrators themselves, so what was in previous decades mere speculation about transmission can now be confirmed,鈥� he said. 鈥淪o, as just one example, we know what the Parkland shooter was googling and that he was looking up both things like the Virginia Tech shooting or the Columbine shooters, but then also a shooting that had just occurred several weeks earlier.鈥�

While many questions about the Texas shooter remain unanswered, Schildkraut said it鈥檚 important to focus attention on the victims and their needs. 

鈥淭here are so many people in years past who can tell you the names of shooters and not one of their victims, let alone all of their victims,鈥� she said. 鈥淲e just really need to refocus the attention on who matters in this, and it鈥檚 not the person who did the killing.鈥�
