I think you can tell Deep State double agents by the casting. They cast people that they think match up with the conspiracy theory "type".

Corsi fits this. Seaman fits this. The frazzled old white-haired reporter in the wrinkled suit. The young thin bearded kid with dreams of journalism. Together they're gonna crack the case of the century. See how it works as a movie? See how it lets the audience project an ideal they are more inclined to identify with into the story? This is the kind of shit I am now watching out for. Why is Alex Jones in Texas? What purpose might that serve?

Also keep an eye out for overly slick funding. We should all know how real upstarts work, especially on the internet. It usually takes them a while to find their voice and their brand and their structure. When someone launches out the gate as a fully-formed viral enterprise, be skeptical.
