CSI: THE EXPERIENCE — Web Adventures. Recording Legible Fingerprints. Introduction to Recording Legible Fingerprints The FBI's Integrated Automated Fingerprint Identification System (IAFIS) is the largest biometric database of criminals in the world.

Recording Legible Fingerprints

Clear, legible fingerprints form the foundation of the Fingerprint Master File, which continues to grow by approximately 13,000 records each day. Agencies submitting fingerprints to the FBI should be aware of the proper procedures for recording fingerprints. The following information will assist agencies in obtaining fingerprints that meet FBI standards. Fingerprint Impression Types Type 4 Rolled impressions are the ten individually-taken fingerprint images rolled from nail to nail. Type 14 Identification flat impressions are taken simultaneously without rolling.

Basic Fingerprint Equipment Fingerprints can be recorded utilizing the following methods: Standard Fingerprint Card (e.g., FD-249 and FD-258)—Use ink to record fingerprint images on standard fingerprint cards. Fingerprinting Process Special Circumstances. The History of Fingerprints. Fingerprints offer a reliable means of personal identification.

The History of Fingerprints

That is the essential explanation for fingerprints having replaced other methods of establishing the identities of persons reluctant to admit previous arrests. 1 The science of fingerprint identification 5 stands out among all other forensic sciences for many reasons, including the following: Other visible human characteristics, such as facial features, tend to change considerably with age, but fingerprints are relatively persistent.

FIREARMS TUTORIAL

The flight path of a bullet includes: travel down the barrel, path through the air, and path through a target. The wounding potential of projectiles is a complex matter. (Fackler, 1996) Internal, or initial ballistics (within the gun) Bullets fired from a rifle will have more energy than similar bullets fired from a handgun. Ballistics of Modern Firearms. In the past two decades Americans have experienced a turbulent relationship with guns. We are compelled as a society to love them through popular culture and are taught to hate them through the acts of newsworthy criminals.

Through all this, it is easy to view guns as a living force by which we can be either entertained or physically threatened. In reality, firearms are nothing more than engineered mechanical devices, capable of acting in ways both defined and directed by human beings.
