For more than a century, forensic firearms analysts have been telling juries that they can match a specific bullet to a specific gun, to the exclusion of all other guns. This claimed ability has helped to put tens of thousands of people in prison, and in a nontrivial percentage of those cases, it’s safe to say that ballistics matching was the only evidence linking the accused to the crime.
But as with other forensic specialties collectively known as pattern matching fields, the claim is facing growing scrutiny. Scientists from outside of forensics point out that there’s no scientific basis for much of what firearms analysts say in court. These critics, backed by a growing body of research, make a pretty startling claim — one that could have profound effects on the criminal justice system: We don't actually know if it's possible to match a specific bullet to a specific gun. And even if it is, we don't know if forensic firearms analysts are any good at it.
