In an interview with John Walsh of “America’s Most Wanted,” President Obama voiced his support for the mandatory collection of DNA samples from U.S. residents who have not been convicted of any crime.
“It’s the right thing to do [to] tighten the grip,” he said.
Obama told Walsh that he supports the position of the federal government and the 18 states that have passed laws requiring the collection of DNA samples from all people arrested for anything from a felony to a misdemeanor. These DNA samples then become part of law enforcement databases that can then be used in future investigations.
In California, police are also allowed to use DNA databases to conduct “familial searches” for people who are close relatives of the person who presumably left behind genetic material at a crime scene. Police can then question the unknown person’s relatives in the hopes of gaining more information about them.
