Comparative bullet-lead analysis

Comparative bullet-lead analysis (CBLA), also known as compositional bullet-lead analysis, is a now discredited and abandoned forensic technique which used chemistry to link crime scene bullets to ones possessed by suspects on the theory that each batch of lead had a unique elemental makeup. CNN PRESENTS Encore Presentation: Reasonable Doubt examined the unreliability of this technique. It has been discontinued as of September 1, 2005.
