2004: Twenty years ago, the idea that DNA fingerprinting could be a useful for solving crimes was introduced. Since that time, DNA collection has become a standard tool for law enforcement, used to both catch criminals, and free the wrongly convicted. In this week's elections, Californians passed Proposition 69 -- a vote to widen the DNA criminal database used in that state. The measure, which passed 61.8% to 38.2%, directs the state to expand its collection of DNA samples to include all convicted felons, some convicted nonfelons, and individuals arrested for certain offenses. Meanwhile, in New York City last week, police made their first arrest under the John Doe Indictment Project, which ties unsolved crimes to DNA profiles. The project allows prosecutors to file charges without knowing a person's identity as long as a DNA profile from evidence is available -- a measure that stops the clock on the statute of limitations on some crimes. In this hour of Science Friday we'll look at how DNA evidence has changed crime fighting in the past 20 years. Plus, a birthday celebration, as the transistor radio turns 50. The first model, the Regency TR1, hit shelves on November 1, 1954. Call in with your questions and comments at 1-800-989-8255 (3-4 Eastern).
