Which of the following is the name of the database that holds digital ballistic information?
a. CODIS
b. AFIS
c. IBIS
d. POTUS
The correct answer and explanation is:
The correct answer is c. IBIS.
IBIS stands for Integrated Ballistic Identification System. It is a system used by law enforcement agencies to capture and store digital images of bullets and cartridge casings that are recovered from crime scenes. The images are stored in a database and can be compared against other digital images from previous investigations to identify ballistic links between different crimes.
IBIS works by scanning the unique markings on fired bullets and casings. When a gun is fired, the markings on the bullet and casing are unique to that weapon. These markings are a result of the firearm’s barrel, firing pin, extractor, and other components. IBIS captures these markings digitally, stores them, and then allows investigators to compare them against a vast database of previously collected ballistic evidence. If a match is found, it can help investigators link different crimes to the same weapon or prove that a weapon was used in a particular crime.
CODIS (a), or Combined DNA Index System, is a database used for storing and comparing DNA evidence, not ballistic information.
AFIS (b), or Automated Fingerprint Identification System, is used to store and compare fingerprints.
POTUS (d) refers to the President of the United States, not a database related to criminal investigations.
IBIS plays a critical role in modern forensic investigations by providing a way to link cases based on ballistic evidence, helping to solve shootings, robberies, and other violent crimes.
