The job of the intelligence officer is to identify those strands that are worth pursuing and then to pursue them until either they are resolved, or they start to look flaky and not worth pursuing, or there is nothing more that can usefully be done. It is a risk-management process. The number of potential leads that can be followed is virtually infinite. On the other hand, covert investigation is extremely resource-intensive and impinges¹ on the human rights of the subject. The threshold² for such investigations is therefore high and the number of investigations necessarily limited. Consequently many potential leads have to be discounted. Decisions on which leads to pursue are vital, but are also complex and rich in judgement.

¹ impinge - to have an effect on (something) often causing problems by limiting it in some way.

² threshold - a point or level at which something begins or starts to take effect.

A former head of German counter-intelligence recently confided: "The best piece of intelligence is the one that only I possess." That spymaster's emphasis on exclusivity and withholding information even from his friends is, alas, the watchword among intelligence chiefs worldwide. And it threatens to undermine efforts to globalize the hunt for terrorists and their bad works.

Timely and credible intelligence - often the merest scrap - can be as decisive in foiling¹ terrorist plotting as any police action, cruise missile, or bomb. That's why the American Congress and the White House are focused on improving information sharing between the CIA and FBI. But the debate has so far overlooked another chronic intelligence failure: the inadequacy of the CIA's liaison with other intelligence services.

One reason for urgent reform is that even though the United States far outstrips other countries in its technical intelligence gathering, many other nations often have better human intelligence, or humint - real live spies.

¹foil - to prevent (someone or something) from being successful.
