There were maps posted of the neighborhood, publically available info about the basements/tunnels, denials from the owners (why lie about their existence?), discovery of pedo symbols on sidewalks in front of these properties where unaccompanied children were often seen dropped off, etc. Although, it could just be the same conspiracy theorists propagating vaxx mandates, vaxx passports, travel restrictons, quarantine camps, and mass government surveillance of the population. Nothing to see here. Move along.
