Comparative bullet-lead analysis

From Wikipedia, the free encyclopedia

Comparative bullet-lead analysis (CBLA) is a forensic technique which uses chemistry to link crime scene bullets to ones possessed by suspects on the theory that each batch of lead had a unique elemental makeup.[1]

The technique was first used after U.S. President John F. Kennedy's assassination in 1963.[1] In 2004, however, the National Academy of Sciences concluded that variations in the manufacturing process rendered the FBI's testimony about the science "unreliable and potentially misleading."[1] The FBI has since abandoned the technique.[1]

However, the U.S. government has fought releasing the list of the estimated 2,500 cases over three decades in which it performed the analysis, which may have led to false convictions.[1]
