Should suspects give their DNA? In my view, if there’s suspicion of involvement in a crime, DNA serves a role akin to fingerprints. For individuals wrongly accused, DNA evidence can exonerate them, while those guilty face the consequences. Despite concerns about privacy invasion, committing crimes arguably forfeits such rights.

UTILIZATION OF CODIS

Given my strong support for DNA utilization, I fully endorse its inclusion in CODIS, the Combined DNA Index System, managed by the Federal Bureau of Investigation:

Local DNA Index Systems (LDIS) where DNA profiles originate. State DNA Index Systems (SDIS) which allows for laboratories within states to share information.
National DNA Index System (NDIS) which allows states to compare DNA information with one another.

The CODIS software comprises various databases tailored to different types of information searches. These databases encompass categories such as missing persons, convicted offenders, and forensic samples gathered from crime scenes. Each state and the federal system have distinct laws governing the collection, uploading, and analysis of data within their respective databases. However, to safeguard privacy, the CODIS database does not include any personally identifying information linked to the DNA profiles. Upon detection of matches to their samples, the uploading agency is notified and responsible for handling personal information in accordance with applicable laws.

EMERGENCE OF PHENOTYPING

With the emergence of Phenotyping and familial DNA analysis, there’s newfound potential for identifying suspects. This can indicate innocence but point to a related individual’s involvement in the crime as well. This type of DNA analysis typically requires law enforcement to request samples and individuals to consent to aiding investigations. Alternatively, it can be employed to verify suspicions about individuals lacking DNA evidence against them.

For further insight the article “Supreme Court Rules DNA Can be Taken After Arrest.” sheds light on the expanding scope of DNA testing post-arrest. As of 2012, 28 states permitted DNA testing upon arrest, although this number may have increased since then.
