Road to Boston: Counterterrorism Challenges and Lessons from the Marathon Bombings [open pdf - 40MB]
"This report examines much of Tamerlan Tsarnaev's personal history and his interaction with Federal agencies, including his radicalization, the 2011 threat assessment carried out by the FBI, and his travel to Russia in early 2012. Additionally, the Committee explores missed opportunities that potentially could have prevented this attack. The Committee has developed seven preliminary recommendations to strengthen our Federal counterterrorism efforts. These recommendations are intended to combat systemic weaknesses the Committee has identified during the course of its investigation, including:  insufficient cooperation and information sharing between Federal agencies and local law enforcement;  Limited communication between Federal agencies;  Inadequate resources for necessary screening of outbound travelers of interest; and  Failure to amend inaccurate or incomplete records held by various agencies. Many of the Committee's recommendations, along with a recommendation to strengthen Congressional oversight of homeland security, echo recommendations included in the 9/11 Commission Report released on July 26, 2004, and are also found in other examinations of terrorist attacks, such as the Senate Homeland Security and Governmental Affairs Committee's review of the Fort Hood shooting. This once again demonstrates that nearly ten years after the release of the findings of the 9/11 Commission, we have yet to fully address these challenges."
