David Langwallner: DNA database is welcome but it will need safeguards
THE Irish Innocence Project welcomes the new DNA database bill, last heard of in 2010. In the US and UK, many people have been exonerated by so-called "cold-searching" of DNA databases.
In addition, actual perpetrators have also been eventually discovered when a DNA database search matched with the crime-scene DNA.
Furthermore, DNA of other individuals found at a crime scene can also assist in showing that someone has been wrongfully incarcerated – particularly if that other DNA is found in multiple crime scenes.
