Wearable police cams allow police officers to record audio and video of their interaction with others and capture the actions of those around them as well. The miniature cameras can be clipped on an officer’s sunglasses, collar, helmet or epaulette and promise to enable reliable documentary evidence of police encounters with the public. Some cameras, like Taser International’s Axon Flex allow video to be streamed real-time via Bluetooth to smartphones.
The key danger is the ability of law enforcement to edit the collected videos, or to use the technology for mass surveillance. Such possibilities have captured the attention of advocacy organizations like the American Civil Liberties Union (ACLU).
