San Francisco is expected to set a groundbreaking precedent on Tuesday by voting to become the first city in the country to ban police from using facial recognition. Part of the reason: concerns about accuracy. “With Caucasian faces, facial recognition is pretty good. It has a 90 to 95 percent accuracy rate,” explains Darrell West, director of the Center for Technology Innovation with the Brookings Institution. “But with minorities, sometimes the accuracy rate drops to 70 percent.”West also says that once a person’s image is in the database, there’s uncertainty surrounding what it could be used for. A Georgetown law study found 1 in 2 American adults is in a law enforcement face recognition network. Law enforcement has argued the technology helps solve crimes or improve investigations. Agencies across the country can use driver’s license photos or mug shots to match someone's identity. “All it's doing is using something that's readily available,” says Sheriff Bob Gualtieri with the Pinellas County Sheriff’s Department in Florida. But it's not just law enforcement using the technology. Stores, airports and some concert venues are all starting to work it into their operations. It's become so mainstream, Congress is now considering a bill to stop businesses from collecting facial recognition data on customers without their permission. “I think people find it very intrusive that you're just walking down the street or going into the store and somebody's recording your face and then attaching your identity to that image,” West says.If the bill in Congress passes, it would be the first federal law on facial recognition. 1656

SCURRY, Texas -- The world of opioid addiction, the path it takes people on and the destruction it causes, is a world foreign to some but all too familiar to others. “When I was 19, is when I was first introduced to opioids,” said Andrew Rogers. Rogers is one of an estimated 1.7 million people in the U.S. addicted to opioids. “I went from pain pills which were easily available to heroin. The pain pills have actually gotten harder and more expensive to get so it’s just cheaper and easier to get heroin,” added Rogers, “from there on it was on.” Before he got hooked on heroin, Rogers had a bright future ahead of him with a full-ride scholarship to college on a pre-med track. But instead he has spent the last nine years in some pretty dark places. “It has made me do things I never thought I would do,” said Rogers. “I’ve overdosed twice. I’ve had friends who have died from it. I’ve actually had to hold one of my friends while he was passing away.” Like so many addicts, Rogers has tried quitting. In total he has been to rehab and detoxed 18 times. At the end of September, he checked himself into treatment again at The Treehouse, a recovery center. “We take the approach of treating the whole person,” said Dr. Ted Bender who is CEO of The Treehouse. “Teaching them how to think more rationally, teaching them how to handle the stress and emotion regulation. Teaching them how to have fun again and enjoy life again and become part of a community.” For nearly a decade, Bender has been trying to help so many people like Andrew Rogers. “We’re losing about a football stadium of people every single year to this epidemic. You know what would make an immediate impact – significant federal funding,” said Bender. “Recovery in itself isn’t the hard part. The hard part is getting the help you need,” said Rogers. When asked what is motivating him this time around, to stay clean and win in this fight against his addiction, Rogers says it is his 4-year-old daughter and his family. 2010

A dangerous and potentially deadly heatwave threatens much of the continental US, with dozens of record high temperatures both in the daytime and in the evening expected this weekend.More than 150 million people in nearly 30 states were under a heat watch, warning or advisory on Thursday morning, according to CNN meteorologist Dave Hennen.Over the next few days, more than 85 percent of the lower 48's population will see temperatures above 90 degrees Fahrenheit, Hennen said, and more than half will see temperatures in excess of 95 degrees.Much of the heat expected for Thursday was forecast to descend on the Midwest and Mississippi, before making its way to the Northeast on Friday and Saturday, Hennen said. 726
