An anonymous reader writes: Cyrus Farivar writes about what's being called a new era in policing: the era of body-worn cameras. They're gaining a foothold in departments around the U.S. after a year of increasing tensions between police and citizens, caused by a series of high-profile shootings. Several research groups are busily evaluating how the cameras affect the way police do their jobs. Many officers welcome the technology — in addition to providing evidence backing up the use of force, it often helps with investigations, capturing details they may miss at the time of an incident. Farivar even goes through a couple of simulated encounters, while pretending to be a cop. The camera easily shows him everything he did wrong. In this way, police officers can also review encounters for training purposes. As more departments adopt them, it's looking like a win-win — police benefit, and the public gets access to some much-desired accountability.
