In this episode, Tao is able to identify the gun dealer Moran by running the fingerprint through AFIS, the Automated Fingerprint Identification Service. This system allows law enforcement to identify a fingerprint and check the history of the individual against a fingerprint database. Fingerprints are scanned directly into the database via a Livescan system.
This episode gave us an opportunity to see the use of weapons by the PHD detectives. Each LAPD officer carries an Austrian-made Glock pistol, adopted by the LAPD in 2003. The Glock is a semi-automatic pistol, known for its safety, light weight, large (15 round) magazine, and ease of use. Calibre varies to suit the taste and needs of individual officers; many favor the .40 calibre Glock 22.
In the US, the FBI holds the Integrated AFIS database, which has a variety of fingerprint identification and analysis capabilities. IAFIS is used not only by law enforcement, but other civil agencies, such as by universities preparing teacher credential candidates, where background checks are important.
The LAPD's internal investigation process was radically overhauled as a result of the Christopher Commission findings that followed the Rampart Division scandal about 10 years ago.
