suraj.sun writes with this excerpt from CNET: "Millions of Americans arrested for but not convicted of crimes will likely have their DNA forcibly extracted and added to a national database, according to a bill approved by the US House of Representatives on Tuesday. By a 357 to 32 vote, the House approved legislation that will pay state governments to require DNA samples, which could mean drawing blood with a needle, from adults 'arrested for' certain serious crimes. Not one Democrat voted against the database measure, which would hand out about $75 million to states that agree to make such testing mandatory. ... But civil libertarians say DNA samples should be required only from people who have been convicted of crimes, and argue that if there is probable cause to believe that someone is involved in a crime, a judge can sign a warrant allowing a blood sample or cheek swab to be forcibly extracted."
