FBI Abandon Bullet-Lead Analysis – Test Used to Link Oswald to JFK

Bullet lead analysis is based on the idea that bullets made with the same batch of lead could be identified. The FBI claimed that each batch of lead had a unique elemental makeup.

The FBI invented bullet lead analysis while investigating (covering up) the JFK assassination. The FBI used the test in the JFK murder to say that all of the bullet fragments found at the scene came from the same batch of bullets. It was of course the same batch that Oswald owned.

In 2005 the FBI quietly stopped using the test. They did this in response to a National Academy of Sciences review of the process that found the test to be unreliable and potentially misleading.


The FBI used the test in hundreds of cases. After all they couldn't just come up with a test, use it in the most controversial case of the century, and never use it again. All of those cases have been tainted by the lie.


Hundreds of defendants sitting in prisons nationwide have been convicted with the help of an FBI forensic tool that was discarded more than two years ago. But the FBI lab has yet to take steps to alert the affected defendants or courts, even as the window for appealing convictions is closing, a joint investigation by The Washington Post and "60 Minutes" has found.

The science, known as comparative bullet-lead analysis, was first used after President John F. Kennedy's assassination in 1963. The technique 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.

In 2004, however, the nation's most prestigious scientific body concluded that variations in the manufacturing process rendered the FBI's testimony about the science "unreliable and potentially misleading." Specifically, the National Academy of Sciences said that decades of FBI statements to jurors linking a particular bullet to those found in a suspect's gun or cartridge box were so overstated that such testimony should be considered "misleading under federal rules of evidence."
