The problem with torture (from a point of view of information) is that the information is NOT reliable AT ALL. Someone under torture will often not only imagine facts, it will actually believe that they are true, and will confess false crimes, especially if presented by the torturer. There is a famous case in Spain in 1910 (a movie was made about it http://en.wikipedia.org/wiki/The_Crime_of_Cuenca) that two men were charged for a murder and tortured until they confess. 12 years later, the "murdered man" reappeared, having spent the time on a nearby town. There are more real life examples showing that people under torture says mainly what the torturer wants, not real life facts. Even in the presented case (the tortured subject truly has some critical information, which is somehow a "tricky case", real life is not that simple), the resulting information can be fake or inaccurate.

Information is more easily obtained in more reliable ways. Aborted terrorist attacks typically aborted in real life because someone will alert the authorities, or someone is being watched, not catching a "bad guy" and torturing it.
