  • Mandatory Dna Fingerprinting

     DNA as a Key Witness Criminals, often unknowingly, leave parts of themselves behind. These pieces are not always visible to the untrained eye. Hair, skin, blood, and fingerprints all contain elements that are unique to each person. It is with DNA testing and fingerprinting, that criminals can be identified and crimes can be linked. This system of testing and matching has become the “most essential and reliable method of catching criminals” in the United States (Lynch 67). Advancing technology...

    DNA fingerprinting is a way of identifying a specific individual, rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology, it has been around since at least 1985, when it was announced by its inventor, Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal...
