My libertarianism pretty much goes out the window when it comes to keeping innocent citizens safe from horrible ones... There isn't much that would offend me if it got murderers, rapists and pedophiles off the streets.
The use of DNA evidence may have just gone a step further --which is more than OK with me...
"Searching DNA records has become a common practice in criminal investigations. Researchers now suggest this could be taken a step further by looking for close DNA matches that might lead police to a criminal through a relative.
They note that 46 percent of jail inmates have at least one relative who also has been in prison. But the idea also raises questions of privacy and other ethical and legal concerns.
Researchers led by Frederick R. Bieber of Harvard Medical School estimate that in a case in which there is a 10 percent chance of finding a criminal through a DNA search, expanding the search to suspects' near relatives could raise the chances to 14 percent.
That could represent an increase of thousands of identifications in the United States, where there have been 30,000 identifications through DNA searches, the researchers said in a paper in Thursday's online edition of the journal Science.
They cite the case of a murder in Britain in which the search of that country's DNA database found a 14-year-old boy was a near match to DNA collected as evidence. That led police to the boy's uncle, who confessed to the crime.
In a similar North Carolina case, a search of the state's offender DNA database led to a near but not perfect match. When police followed up, the brother of the individual located through DNA confessed, the researchers reported." (source)
Of course, there are people speaking out against it. I can't understand why -really. The use of DNA in criminal investigations is one of the most important advances society has made as far as I'm concerned. It fingers the guilty beyond a shadow of a doubt --and has exonerated the innocent...
