FILE - In this April 14, 2011 file photo, Supreme Court Justice Anthony Kennedy testifies on Capitol Hill in Washington. A sharply divided Supreme Court on Monday said police can routinely take DNA from people they arrest, comparing a DNA cheek swab to other common jailhouse procedures like fingerprinting. "Taking and analyzing a cheek swab of the arrestee DNA is, like fingerprinting and photographing, a legitimate police booking procedure that is reasonable under the Fourth Amendment," Kennedy wrote for the court's five-justice majority.

In his lab at the Harvard Medical School in Boston, George Church, Harvard Medical School Genetics professor, shows DNA sequence data for Dr. John Halamka, chief information officer, following a news conference on Monday, Oct. 20, 2008 where a group of mostly scientists and researchers said they will post their medical records and DNA sequence of some of their own genes online for the sake of research. Both George Church and Dr. Halamka are part of the group that plan to post their medical and DNA sequence of some of their own genes online.
