Andy Ngo is knowingly re-posting 4chan troll false-flag propaganda claiming that long-time anarchist publishing house @CrimethInc is calling for demonstrations on November 5. CrimethInc. has a website and a variety of public platforms—if they were actually sponsoring a demonstration, they would have announced so themselves.
Doubt us? Go have a look yourself: http://crimethinc.com/
Andy works closely with people involved in the Trump campaign. Various law enforcement actors take cues directly from him. But as this example illustrates, he has no scruples about publishing false information. Spreading hate-driven lies in hopes of emboldening potential mass shooters is Andy's life's work.
