The Global Gen World

A system of national, state and local DNA databases used for the storage and exchange of DNA profiles is serving an important role in expediting resolution of criminal cases. The use of DNA databases can facilitate linkage of one crime scene evidence to another. It allows the comparison of crime scene evidence to a database of DNA profiles obtained from convicted offenders. The ability to link DNA evidence obtained from different crime scenes can identify serial killers.

However, this system’s potential can only be maximized when supported by relevant laws such as requiring offenders of particular offenses to provide DNA samples. The existence of a comprehensive DNA database not only helps solves crimes but most importantly prevent it to be committed by the very same offenders.
