Genetic evidence has become an essential tool in modern crime labs. With amazing precision, it can tie a suspect to the scene of a crime -- or exonerate a falsely accused person. Speaking earlier this month before Congress, Richard Townsend, director of Utah's Bureau of Forensic Services, said "the advantages of DNA technology cannot be overstated. It has to be considered the most significant breakthrough science has made to assist law enforcement in identifying perpetrators of crime." Millions of dollars have been spent to upgrade forensic laboratories to take advantage of the new technology. Several years ago, the FBI established its Combined DNA Information System (CODIS), aiming to pool genetic information collected by police departments around the country. State police departments collect samples, which are then analyzed either by state forensic labs or private companies. The data is then merged into one of two national databases -- one for samples taken from convicted felons, and one from samples collected at crime scenes. Police departments love DNA fingerprinting technology, saying it has allowed them to crack cases that may have been next to impossible to solve in the past. But not all people agree on the best way to create, manage, and use genetic information. For instance, rules vary from state to state on whose DNA gets collected. Should samples be taken from all suspects in a case? How long should samples be retained? Is there a danger that information about medical conditions, family relationships, or personal traits might be revealed through such genetic tests? Should investigators be allowed to conduct 'DNA dragnets' of large numbers of people? In this hour, we'll take a look at the technology and policy of forensic DNA testing and DNA databases. Plus, we'll check in with a company developing biodiesel technology. Biodiesel, a fuel based on materials such as used vegetable oil, has been suggested by some as a possible aid to a future oil shortage. We'll hear about a biodiesel station opening this week in San Francisco.
