The Seattle Police Department has been working toward this moment for more than a year. Footage from the cameras can be used as evidence against suspects, and help monitor the behavior of officers. Research has found that departments using such cameras have experienced a decline in assaults on officers, as well as the need for officers to use force.
SPD has worked with a number of different groups, including the American Civil Liberties Union and Community Police Commission, to develop policies around the use of body worn cameras. In addition, the department sought advice from an International Association of Chiefs of Police (IACP) body-worn video expert, who worked has worked with departments across the country on this issue.
You noticed that the picture became oddly distorted around 25 seconds in, as soon as faces became visible. A Gaussian blur was rendered, making it impossible to identify individuals.
All this makes me think of several of my favorite sf authors and their work. In his 2007 novel Halting State, Charles Stross writes about lifelogs, which are body camera videos uploaded to the police cloud servers.
You shake your head and climb out of the car, tapping your ear-piece to tell your phone to listen up: "Arriving on SOC, time-stamp now. Start evidence log." It's logging anyway - everything you see on duty goes into the black box - but the voice marker is searchable. It saves the event from getting lost in your lifelog.
