In short, the article's claims are patently false. For the record, the FBI has not deputized InfraGard, its members, businesses, or anything else in the program. The title, however catchy, is a complete fabrication. Moreover, InfraGard members have no extraordinary powers and have no greater right to "shoot to kill" than other civilians. The FBI encourages InfraGard members -- and all Americans -- to report crime and suspected terrorist activity to the appropriate authorities.The FBI response also states that Rothschild has "refused even to identify when or where the claimed 'small meeting' occurred in which issues of martial law were discussed," and promises to follow up with further clarifying details if they get that information.
I've updated my own response to Rothschild to include the above information.
