The only thing implausible here is that the FBI or other Federales would reveal intelligence sources and methods so carelessly. The fact remains that the gov't maintains systems that monitor and log online activity with automatic flagging/storage based on keywords. I do find it unlikely that peon-agents and JTTF types have routine access to that data, but I wouldn't have been surprised to learn that some info regarding a potential threat might have been passed down to peon-agents with a suggestion or task for them to follow up on.
