Named as defendants in the suit are the owners of several social media platforms and streaming services; RMA Armaments, an Iowa-based body armor maker; Vintage Firearms, a New York-based gun store; MEAN LLC, a Georgia-based firearms accessory manufacturer; and Gendron's parents.
"Social media companies must be held responsible for perpetuating hate and violence."
The social media and streaming services named in the filing include: Meta, Facebook's parent company; Alphabet, which owns Google; Snap, which operates Snapchat; Discord; Reddit; Amazon, operator of the Twitch live-streaming service; as well as the message board website 4chan.
"The Buffalo shooter was radicalized by social media. Rather than stop the spread of hate, those platforms made money off it," Giffords Law Center
tweeted. "We're helping bring this lawsuit because social media companies must be held responsible for perpetuating hate and violence."
"Payton Gendron has pled guilty to these murders, and is no longer a danger to society," Elmore said in a statement. "However, the social media platforms that radicalized him, and the companies that armed him, must still be held accountable for their actions. Our goal, on behalf of our clients, is to make this community and our nation safer and prevent other mass shootings."
As
ABC Newsreports:
The lawsuit alleges the social media platforms aided in rapidly spreading Gendron's hate via copies of his livestream of the shooting across multiple platforms where it became known as the "murder video" and viewed by more than 3 million people.
Gendron used Amazon's Twitch to livestream the first two minutes of the rampage before it was taken down by the operators of the popular gaming platform, the lawsuit states.
Despite it being taken down, the video was downloaded to 4chan, according to the suit.
In a
statement, Matthew Bergman, founding attorney of the Social Media Victims Law Center, said that Gendron "was motivated to commit his heinous crime by racist, antisemitic, and white supremacist propaganda fed to him by social media companies."
"These posts led him down a rabbit hole of increasingly radical sites, where he was indoctrinated in white supremacist replacement theory and violent accelerationism," Bergman added. "This horrible crime was neither an accident nor coincidence, but rather the foreseeable result of social media companies' intentional decision to maximize user engagement over public safety."
The lawsuits come as Buffalo prepares to commemorate the first anniversary of the massacre on May 14.
"I'm hoping that something will come out of it," plaintiff Barbara Massey Mapps, sister of victim Katherine "Kat" Massey,
said of the suit in an interview with ABC News.
"These big companies only know one thing, money. So, you've got to hurt them."
"Every day or every few days, all you hear about is a mass shooting," Mapps added. "You've got to start somewhere, in order for them to get the message. These big companies only know one thing, money. So, you've got to hurt them. How many people do you want to see dead?"
Responding to the lawsuit, a Snap spokesperson said: "We have a zero-tolerance policy for hate speech and discrimination of any kind. We deliberately designed Snapchat differently than traditional social media platforms and don't allow unvetted content to go viral or be algorithmically promoted. Instead, we vet all content before it can reach a large audience, which helps protect against the discovery of potentially harmful or dangerous content."
Last December, the city of Buffalo
sued several gun manufacturers and distributors for "endangering the safety and health of the public."
Friday's lawsuit follows
another filed on Thursday by New York Attorney General Leticia James, a Democrat, against MEAN, accusing the company of helping Gendron evade the state's ban on high-capacity assault-style rifles.
"The racist mass shooting at the Tops grocery store in Buffalo was one of the darkest days in the history of our state and our nation," James said in a
statement. "We lost 10 innocent lives because a hate-fueled individual was able to make an AR-15 even deadlier through a simple change at home."
