DNA Collection From All Those Arrested

Suspects arrested or detained by federal authorities could be forced to provide samples of their DNA that would be recorded in a central database under a provision of a Senate bill to expand government collection of personal data.

The controversial measure was approved by the Senate Judiciary Committee last week and is supported by the White House, but has not gone to the floor for a vote. It goes beyond current law, which allows federal authorities to collect and record samples of DNA only from those convicted of crimes.

"When police retrace the history of a serial predator after he is finally caught, they often find that he never had a prior criminal conviction, but did have a prior arrest," Sen. Jon Kyl (R-Ariz.) said in a statement. "That means the only way they are likely to catch such a perpetrator after his first crime -- rather than his 10th -- is if authorities can maintain a comprehensive database of all those who are arrested, just as we do with fingerprints."

The provision, co-sponsored by Kyl and Sen. John Cornyn (R-Tex.), does not require the government to automatically remove the DNA data of people who are never convicted. Instead, those arrested or detained would have to petition to have their information removed from the database after their cases were resolved.

Privacy advocates are especially concerned about possible abuses such as profiling based on genetic characteristics.
