A federal appeals court today unanimously upheld California's practice of collecting DNA from people arrested on suspicion of a felony.

The ruling by an 11-judge panel of the U.S. 9th Circuit Court of Appeals cited a decision by the Supreme Court that upheld a similar but narrower program in Maryland.

Since 2009, California has been collecting DNA from anyone arrested in a felony case and storing the genetic profile in a database.

People who are not later convicted may apply to have the DNA sample destroyed and the genetic profile expunged, but critics say the process is challenging and cumbersome.
