The DNA for detecting patterns

Changing the Game: The DNA for Detecting Criminal Activity Patterns.

Over the last two decades, one of the most significant developments in solving specific violent and sexual crimes has been the wide-ranging collection and testing of DNA evidence. Where once investigators were hamstrung by more primitive forms of physical evidence and less-than-reliable eyewitness accounts, today DNA evidence provides a more scientific and verifiable means of linking specific perpetrators to the victims they have committed their crimes against.

Of course, there have always been concerns about whether the use of DNA evidence by law enforcement violates suspects’ rights. But in practice, it has actually proven invaluable in confirming the innocence of the wrongly accused. The newspapers regularly run accounts of inmates being released from prison years after their convictions, which may have been based on faulty eyewitness accounts, the inability to establish a credible alibi and even the subjective points of view of law enforcement officials.

In short, DNA testing is a benefit to protecting the liberty of the innocent while sealing the fate of the guilty.
