From FBI's website: "The New York Joint Terrorism Task Force brings together representatives of 49 local, state, and federal agencies to run down any and all terrorism leads, develop and investigate cases, provide support for special events, and proactively identify threats that may impact the area and the nation. We also have satellite Joint Terrorism Task Forces working out of Long Island, Westchester County, and Orange County." Source: http://www.fbi.gov/newyork/about-us/our-partnerships/partner...

It makes full sense that the FBI would get a report and share with local law enforcement (members of JTTF) to follow up. I'm still very skeptical that this all originated with google searches, but the story of "JTTF agents" checks out.
