On May 14, 2022, ten Black people were killed at a Tops supermarket in Buffalo, New York. Three other people were injured. Their lives were taken in a racially motivated mass shooting. The attacker had absorbed and repeated an extremist conspiracy theory claiming that white people were being intentionally replaced. It was not a verified account of the world. It was a racist falsehood. Investigators later documented that he used online spaces both to strengthen those beliefs and to try to spread his message through the violence itself.

Five months later, on October 18, 2022, the New York Attorney General released an investigation into the part online platforms played. The report drew on thousands of pages of records, content and responses from platforms. It examined how harmful material was encountered before the shooting, how the attacker sought an audience, and why copies of the violent video could keep spreading after the original livestream was stopped. This is a source-led investigation of that chain, not a reprint of an attacker’s propaganda.

Why It Matters

A false story can have real victims when someone uses it to justify violence. The Buffalo case shows more than a single misleading post. It shows a network of ideas and online channels that made a racist conspiracy feel credible to the person who believed it. It also shows why correcting a particular rumor after a tragedy is only part of the work. Readers need to know how the harmful belief was built, how it was carried, what officials established and where proposed policy changes remain just proposals.

We will not reproduce the attack footage, link to the original extremist document, publish hateful slogans, or name online communities as a place to find them. The public record can explain the failure without sending more attention to the material the attacker wanted copied.

Go Deeper | From False Premise to Public Harm

The original false idea

The conspiracy theory that influenced the attacker portrays demographic and social change as a plot against white people. This claim has no valid basis as a planned replacement scheme. It turns neighbors and fellow citizens into imagined enemies. The Justice Department’s June 15, 2022 criminal complaint described the attacker’s stated goal as targeting Black people and encouraging others to commit similar acts. That official account is not a reason to repeat the conspiracy as though it were a legitimate disagreement about facts.

Investigators reported that the attacker prepared writings before the shooting. The details in those materials were relevant to a federal hate-crime investigation because they helped establish what he said he wanted to accomplish. Reading them as evidence of intent is different from distributing them as political messaging or treating their assertions as proven true.

How the online environment mattered

New York’s Attorney General examined fringe discussion sites, social networks, livestreaming services and messages shared on several major platforms. The office reported that the attacker described consuming racist and antisemitic material in online spaces where moderation was limited. Over time, those messages reinforced his hostility. The state investigation characterized this process as online radicalization.

That conclusion does not mean every user of a named platform committed a crime. It does not mean a single website mechanically made someone kill. It describes the evidence investigators gathered about this individual: the content he sought, the ideas he adopted, the records of his preparations and his effort to publicize violence.

The Attorney General’s office reviewed material and policies from the companies, including responses obtained during its investigation. That matters because the inquiry was broader than an opinion formed by looking at a few screenshots. Still, its findings are the office’s documented conclusions, not a substitute for all original private platform records being publicly available.

Planning was not the same as a spontaneous outburst

The Department of Justice alleged that the attacker selected the Tops store because it served a largely Black neighborhood. Federal investigators described research, visits to the area and a written plan. The planning record contradicts any attempt to present the shooting as an accidental encounter or a sudden argument at the store. The attack was directed at people because of race.

Those details also explain why online material matters as evidence. The false ideology was paired with deliberate choices. But a criminal complaint filed in June 2022 remains an allegation at that historical stage; later court developments must be reported with their own dates.

The livestream was part of the harm

The attacker broadcast the shooting through an online livestream. The New York investigation found that the platform cut off the broadcast within about two minutes after the violence began. That was a faster response than some past high-profile livestream cases. But it did not erase the content people had already seen or recorded.

One important distinction: a platform’s removal of its original feed is not the same as removal of every later copy. The Attorney General reported that material was captured and redistributed across other services. Some platforms reacted quickly; others struggled with links to copies hosted elsewhere. A reader hearing only that the original service acted within two minutes could wrongly conclude that the entire online spread had ended.

Why the replay problem cannot be treated as harmless

Reposted footage can force victims’ families and survivors to encounter the violence again. It can also reward an attacker’s wish to be seen and copied. This is why this article describes the circulation without displaying or linking the footage. Reposting shocking content is not required for a reporter to establish that the footage existed or that a platform struggled to stop its spread.

The Attorney General asked for stronger transparency, improved moderation practices and changes to how violent livestreams are handled. The report was an investigative and policy document. Its recommendations were not automatically laws, and they should not be presented as measures already adopted nationwide.

The second wave: claims that deny the victims’ reality

In the days after the massacre, false online posts claimed the attack was staged. Some tried to reinterpret routine news-production mistakes or interview details as proof. Those are individual claims for the separate Rumor vs. Reality hub, where the original clip or screenshot can be checked against an authenticated source. They are not evidence that the killing did not happen.

The bigger Smoke & Mirrors pattern is different. First, a fabricated racist narrative helped the attacker identify innocent people as enemies. Then his attempt to broadcast the shooting made its images part of the public trauma. Finally, other false narratives sought to cast doubt on the reality of the victims’ deaths. These events involved different sources and motives, and this article does not presume that every person who repeated a falsehood intended the same harm.

Where the legal record stands separately

The attacker, Payton Gendron, pleaded guilty to New York state crimes tied to the shooting and was sentenced in February 2023 to life in prison without parole. That is an adjudicated state outcome. The federal case is separate. The Justice Department filed federal hate-crime and firearm charges; a federal jury-selection process was underway beginning October 13, 2026, according to public court reporting. We have not verified a later final federal jury verdict for this retrospective, so we do not invent one.

Keep those legal paths apart. An investigation of platform behavior is not a verdict against every platform. A state guilty plea is not the same legal event as a pending federal death-penalty proceeding. And a public official’s recommendation about internet regulation is not a court order.

How to report the victims without repeating the attacker’s message

The people murdered at Tops were shopping, working and living ordinary lives in their own neighborhood. The supermarket was a place where people knew one another. The attacker’s effort to turn them into symbols of a hateful ideology does not define who they were. Reporting should keep their names, families and community in view without reproducing violent media or giving extremist material a new audience.

That approach is part of verification. It asks not only whether a piece of content existed but also why publishing it would help the public understand the truth. An accurate article may describe the existence of an extremist document, cite an official investigation and explain the documented connection without pasting the document’s propaganda into the story.

What Happens Next

Future coverage should check official federal court orders for the status and outcome of the separate federal prosecution. Any new policy or platform-transparency claim should be compared to the actual law or adopted policy, not just the October 2022 recommendations. If a new report claims another company did or did not remove content, the original timestamped company data matters.

The main findings here are established by the October 18, 2022 New York Attorney General report and the Justice Department’s public criminal account. Later state and federal case milestones are labeled with their real dates. The false premise at the heart of the attack should never be treated as an ordinary unverified theory. It was racist propaganda whose use in planning and publicizing violence has been extensively documented. The victims’ lives, not the attacker’s demands for attention, remain central.
