[…]. In the report the committee offers their findings, conclusions and recommendations, "the Committee found there were systemic failures across the Intelligence Community (IC), which contributed to the failure to identify the threat posed by Abdulmutallab. Specifically, the NCTC was not organized adequately to fulfill its missions. Following 9/11, Congress created the NCTC and charged it with serving as 'the primary organization in the United States Government for analyzing and integrating all intelligence possessed or acquired by the United States Government pertaining to terrorism and counterterrorism . ... ' In practice, however, the Committee found that no one agency saw itself as being responsible for tracking and identifying all terrorism threats. In addition, technology across the IC is not adequate to provide search enhancing tools for analysts, which contributed to the failure of the IC to identify Abdulmutallab as a potential threat."
