Why no one can afford to keep every suspected terrorist under continuous surveillance

David Wise writes: To keep a target under continuous surveillance, according to one experienced FBI source who asked to remain anonymous, could require three eight-hour shifts or perhaps two 12-hour shifts, with four special agents each shift. Several cars would be needed, sometimes even airplanes. If only one car was used, the person might quickly realize he was being followed.

“If you are just sitting around in the street, somebody’s going to notice you,” Parker explained. “If it’s a real sensitive case, you just cannot be made. You would run five or six cars, maybe seven or eight. If you don’t want any chance of the target making you, the average is three shifts, four guys to a shift, two cars — that’s a minimum. Three shifts, so 12 agents. If it’s a really important case, you could easily double that.” That minimum translates into 24 agents in three shifts of eight agents to keep watch on a single target.

Parker, who spent much of his career tracking Soviet and Russian spies, noted, “Most surveillance subjects are not moving more than a few hours a day. So you may also have to set up an OP [observation post],” often a house or apartment overlooking the target.

Just as the French services wiretapped the cellphones of the Paris terrorists, the FBI does not limit itself to physical surveillance of a subject. “You would also have technical means,” one surveillance specialist, who asked to remain anonymous, said. “If you run 24-hour surveillance, you have telephones, both cell and land lines, MISUR [microphone surveillance] and stationery lookouts.”

Agents might also lock onto the GPS of the suspect’s car, to see where he or she is going. In one high-profile espionage case, the FBI placed radio receivers at fixed points around the Washington area and was also able to plant an electronic device in the suspect’s car. When the target car passed by one of the receivers, the time and location were recorded. This setup was similar to the E-ZPass system, which is used by commuters to breeze through toll plazas without stopping.

With so much manpower required to monitor just one suspect, FBI supervisors often resist mounting a 24/7 surveillance. It takes away agents who might be working other cases. A smaller field office might not have enough agents. [Continue reading…]
