Her husband, in the same time frame, was Googling backpacks. Wednesday morning, six men from a joint terrorism task force showed up at their house to see if they were terrorists. Which prompts the question: How'd the government know what they were Googling? Catalano (who is a professional writer) describes the tension of that visit. [T]hey were peppering my husband with questions. Where is he from? Where are his parents from? They asked about me, where was I, where do I work, where do my parents live. Do you have any bombs, they asked. Do you own a pressure cooker? My husband said no, but we have a rice cooker. Can you make a bomb with that? My husband said no, my wife uses it to make quinoa. What the hell is quinoa, they asked. ... Have you ever looked up how to make a pressure cooker bomb? My husband, ever the oppositional kind, asked them if they themselves weren’t curious as to how a pressure cooker bomb works, if they ever looked it up. Two of them admitted they did. The men identified themselves as members of the "joint terrorism task force." The composition of such task forces depend on the region of the country, but, as we outlined after the Boston bombings, include a variety of federal agencies. Among them: the FBI and Homeland Security.
