=== Faulty bullet analysis ===
For over 40 years, the FBI crime lab in Quantico had believed that lead alloys used in bullets had unique chemical signatures. It was analyzing the bullets with the goal of matching them chemically, not only to a single batch of ammunition coming out of a factory, but also to a single box of bullets. The [[National Academy of Sciences]] conducted an 18-month independent review of [[comparative bullet-lead analysis]]. In 2003, its National Research Council published a report whose conclusions called into question 30 years of FBI testimony. It found the analytic model used by the FBI for interpreting results was deeply flawed, and the conclusion, that bullet fragments could be matched to a box of ammunition, was so overstated that it was misleading under the rules of evidence. One year later, the FBI decided to stop conducting bullet lead analyses.<ref>{{cite web |title=FBI Laboratory Announces Discontinuation of Bullet Lead Examinations |work=FBI |url=https://www.fbi.gov/news/pressrel/press-releases/fbi-laboratory-announces-discontinuation-of-bullet-lead-examinations |date= September 1, 2005 |publisher=FBI National Press Office |access-date=December 6, 2014 |url-status=live |archive-url=https://web.archive.org/web/20141208182140/http://www.fbi.gov/news/pressrel/press-releases/fbi-laboratory-announces-discontinuation-of-bullet-lead-examinations |archive-date=December 8, 2014}}</ref>

After a ''[[60 Minutes]]''/''[[The Washington Post]]'' investigation in November 2007, two years later, the Bureau agreed to identify, review, and release all pertinent cases, and notify prosecutors about cases in which faulty testimony was given.<ref>{{cite news |url=https://www.cbsnews.com/news/evidence-of-injustice/ |title=Evidence Of Injustice |work=CBS News |date=November 18, 2007 |access-date=November 22, 2007 |url-status=live |archive-url=https://web.archive.org/web/20071120202358/http://www.cbsnews.com/stories/2007/11/16/60minutes/main3512453.shtml |archive-date=November 20, 2007}}</ref>
