3 enhancement computer has made in law enforcement?

Answer 1

The most important enhancement that computers have provided to law enforcement are:

1. Data bases containing vast amounts of information pertaining to crimes and known criminals from their own jurisdiction or any jurisdiction, including international. Data bases containing helpful information from scientific and commercial sources such as scientists or scientific methods, tire pattern designs, shoe designs, firearm and ballistic information, etc. that may be needed in the investigation and/or prosecution of crimes that may not otherwise be available to investigators.
2. Access to scientific testing methods that can measure, analyze, identify, or otherwise quantify the properties of evidence that is faster and often more accurate, or even not possible using manual methods.
3. Speed of access to vast amounts of information for investigation of crimes that greatly reduce the speed and increase investigators ability to solve crimes, or solve crimes that may not be solvable without access to this information.

Good examples of information available to any jurisdiction, no matter how small or ill equipped are FBI data bases, NIH data bases, the Smithsonian forensic anthropology scientists, the University of Tennessee "body farm" scientists, Interpol, and the criminal and scientific information of other countries with which the US may have a relationship.
