In video imaging, mug shots are taken by using a high- resolution video camera. The image is then sent to a computer that converts the image to a digital computer message. This message is stored on magnetic or optical disk. Images can then be printed out in either color or black and white. A line-up can be created by calling up a suspect's image and directing the computer to find matches to the suspect based on the suspect's attributes. The images that are chosen can then be printed out and presented to a potential witness almost immediately. Live scan fingerprinting involves a computer system used to replace the ink method of taking fingerprints. Fingers are rolled across a platen, scanned into a computer, and converted to a digital form of storage. The computer then prints out fingerprint cards on a laser printer. Booking sheet information from the booking computer can be moved directly to the live-scan printer. An automated fingerprint identification system involves work station terminals that allow for searching of the Western Identification Network data base for fingerprints. Investigators use the system to identify latent fingerprints. During the booking process, the jail uses this system to identify inmates who misrepresent or refuse to provide their identity. The article also briefly describes interagency computer systems and what the future holds for technologies. 3 photographic illustrations
