Members of law enforcement work at the scene of a weekend shooting at a Tops supermarket in Buffalo, New York, U.S. May 19, 2022. Also sued were three retailers--Mean Arms, Vintage Firearms and RMA Armament--that allegedly sold firearm equipment and body armor that Gendron used. Alphabet (GOOGL.O) and Google, which own YouTube, are also defendants, as are Gendron's parents. Through the defendants' alleged negligence, Gendron "gained the racist motivation, tools and knowledge necessary for him to commit the mass shooting," the complaint said.
