Agent Jack Pierson: The device we're recovering is highly sophisticated with a built-in backup system, so we now know that this guy has expert knowledge of both electronics and explosives.
Agent Smith: This "guy"?
Agent Jack Pierson: We now believe an individual set off the detonation witnessing the aftermath last night from a nearby vantage point and we fully expect him to obsessively follow this investigation.
Agent Wallace: You mean in the press?
Frank Black: Closer. From his home. The bomb is complex, intricate. Perhaps overly so. I believe this trait extends to his obsessions. Expect to find an array of eavesdropping devices - scanners, cell phone cloners, RF receivers. he's listening to every transmission we make. It's his way of inserting himself into the chaos, the chaos he creates.
