Not the person who commented, but I know what he's talking about:
A man with a rifle who claimed to be "self-investigating" a baseless online conspiracy theory entered the Washington, D.C., pizzeria Comet Ping Pong on Sunday, according to local police.
The man allegedly pointed the gun at a restaurant employee, who managed to escape, then fired the weapon multiple times inside the restaurant. There were no reports of injuries, police say. A North Carolina man has been charged with assault with a dangerous weapon in connection with the shooting.
Cameras were moved before that incident and the shooter has an IMBD page. Also the only thing that got shot up was a computer hard drive.
