Drone technology is improving and becoming more affordable. The commercial market could be huge. This week's Consumer Electronics Show in Las Vegas is featuring new models that are very attractive to photographers and journalists, not to mention law enforcement. But there is already push-back from privacy advocates. Guest host Judy Muller considers the up- and downsides of drones. Also, President Obama is set to announce "Promise Zones" in five US cities, and a new memoir from former Secretary of Defense Robert Gates delivers some scathing criticism of the Obama Administration.
