How can the reliability of information obtained during an interrogation be assessed?

The reliability of information obtained during an interrogation is best assessed by corroborating the information with other evidence. This method involves verifying the details provided by the suspect through independent sources or factual evidence. When information is consistent with external facts, it increases its credibility and the likelihood that the suspect is providing accurate information. Corroboration acts as a safeguard against the inherent uncertainties of an interrogation setting, where suspects may incentivize to provide falsehoods or misrepresentations due to fear, pressure, or other psychological factors.

This approach aligns with the investigative practice of seeking a holistic view of the case, where corroborated information can lead to more informed conclusions regarding the validity of the suspect’s statements. Relying solely on the suspect's word or an interviewer's instincts does not provide an objective measure of reliability, and ignoring inconsistencies presents a serious risk of misunderstanding the true circumstances of an investigation. Thus, corroboration stands out as the most effective method for assessing reliability in interrogation settings.
