The ABIN helps police across Australia electronically match crime scene ballistic evidence to the weapon used in the crime. It also links crimes if the same firearm is used at multiple scenes.
This national solution builds on existing ballistic libraries that operate in a number of states, and allows police to search for a ballistic signature of a firearm to see if it is linked to other crimes across Australia. Firearms leave unique microscopic markings on the surface of fired projectiles. Ballistic experts examine and compare these markings, linking ballistic evidence to crime scenes and recovered firearms. This information is used as an intelligence source to assist in linking firearms to suspects and crimes.
ABIN is only available to police agencies.
