Facial recognition technology is all around us—it’s at concerts, airports, and apartment buildings. But its use by law enforcement agencies and courtrooms raises particular concerns about privacy, fairness, and bias, according to some researchers. Some studies have shown that some of the major facial recognition systems are inaccurate. Amazon’s software misidentified 28 members of Congress and matched them with criminal mugshots. These inaccuracies tend to be far worse for people of color and women. We'll talk about how AI is guiding the decisions of police departments and courtrooms across the country—and whether we should be concerned. Plus: Scientists were threatened with firings after the National Weather Service projections for Hurricane Dorian contradicted President Trump’s tweets, and more of the biggest science stories from the week.
