DNA Database for Criminals

Although DNA detection might have advantages over fingerprint dusting, the test is nevertheless fallible. Environmental factors at the crome scene such as heat, sunlight, or bacteria can corrupt any genetic data. Any DNA evidence must be stored in sterile and temperature controlled conditions. Criminals have been suspected of cantaminating samples by swapping saliva. There is room for human error or fraud in comparing samples taken from supects with those removed from a crime scene. The accuracy of any genetic profile is dependent upon he number of genes examined. Even a complete DNA profile cannot indicate the length of time a suspect was present at a crime scene or the date in question. The mere creation of a database cannot be the panacea for crime detection.

The invasiveness of the database resides in the information being maintained on file, rather than in the procedure for obtaining genetic data. The decision to pass personal info to mortgage or insurance agencies is governed by individual consent. The provision of DNA would have to be mandatory, for otherwise those liable to commit crime would simply refuse to provide a sample. When the citizen releases information to outside agencies he receives a service in return. Finally, there is a subtle yet significant difference in the attitude of government towards the citizen that is conveyed by the creation of a database. Every citizen, some from the moment of their birth, would be treated as potential criminal.
