Once convicted criminals have their DNA fingerprints in CrimTracs database police are able to identify them faster as suspects if they re-offend which saves investigation time When confronted with DNA evidence guilty suspects may be more likely to confess and plead guilty also saving police time and reducing court costs The DNA database gives Australian police a tool to increase the closure rate of not only serious offences but also high volume crimes such as burglaries As many crimes are solved more rapidly the police will be free to investigate other crimes that are outstanding As more crimes are investigated and solved Australia will become a safer place to live This is a major argument for all people convicted of a crime to have their DNA fingerprints stored on the DNA database However despite the present success of DNA databases such as CrimTrac concerns are raised about the ethics presently involved and also the future repercussions of such a database being in existence One present concern is that with so many samples being collated there is a remote chance that two DNA fingerprints would look the same but not be from the same person besides the case of identical twins If a convicted criminal has their DNA on file and is later found to be a similar match to DNA found at another crime scene it would be very difficult for the person to argue that he or she had nothing to do with the crime not to mention impossible for an identical twin to argue on DNA evidence alone It can also be argued that convicted criminals may be implicated in any other crime simply based on where they happened to leave a DNA trail Concerns are raised that convicted criminals will be treated as second-class citizens Despite people regarding DNA as being very strong in criminal trials forensic experts talk only about the probability that DNA came from a defendant and not yes
