WHITE HOUSE: Gibbs reiterated today that sufficient information was obtained from the fizzled panty bomber Abdumutallab in the 50 minutes he was interrogated before he was read his Miranda rights. This gratuitous assertion withers under the most cursory of examinations.
One of the key components of any successful interrogation is allowing enough time. 50 minutes is not even enough to get started:
Investigators must remember that successful interrogations require a certain amount of time to complete. Some confessions or admissions come quickly, but most do not. Those involving a polygraph examination usually occur between the second and third hours of the interrogations session. Generally, the chances of obtaining a confession increase 25 percent for every hour (up to 4 hours) of interrogation.12 Investigators spend up to the first hour of the session learning about the subjects, building rapport, obtaining background information, and discussing the crimes. Verbal and nonverbal responses form the basis of the investigators’ evaluations concerning the subjects’ degree of truthfulness and degree of criminal involvement. It takes time for investigators to observe these responses and relate them to the critical issues of the cases. Stopping after 30 minutes or an hour of interrogation dooms investigators to a 75 percent interrogation failure rate.13 The Art and Science of Criminal Investigation
