What does IBIS do in the context of ballistics?

IBIS, or Integrated Ballistic Identification System, serves a critical role in ballistics by comparing digital images captured from fired bullets and cartridge casings. This system utilizes advanced imaging technology to create detailed representations of the unique markings that are left on bullets and casings when a firearm is discharged. These markings are often referred to as "striation patterns" and "firing pin impressions," and they serve as fingerprints for each firearm.

The strength of IBIS lies in its ability to quickly analyze and compare these images across a vast database to identify potential matches. This is crucial for law enforcement investigations where linking a recovered bullet or casing to a specific firearm can provide key evidence in solving shootings or violent crimes. The automated aspect of IBIS significantly enhances the efficiency of ballistics investigations, enabling forensic experts to sift through large amounts of data swiftly.

The other options present various aspects of firearm investigations but do not accurately represent the primary function of IBIS. While tracking firearm ownership and detecting ammunition type are important in firearms investigations, they do not pertain to the imaging and comparison capabilities that IBIS uniquely provides. Similarly, measuring kinetic energy of bullets is related more to the physics of firearms rather than ballistic identification itself. Thus, the correct answer underscores the core purpose of
