After conflicts between protestors and police in Ferguson, Mo. yesterday — particularly in the wake of militarized police officers arresting Washington Post and Huffington Post reporters working in a nearby McDonalds — some have suggested that on-body cameras should be more widely used among on-duty police. The Verge produced a story and documentary last year about Axon Flex, perhaps the most advanced of these on-body police cameras, and the advantages and disadvantages of the technology. In that story, civil rights attorney Scott Greenwood talked about his work to establish concrete rules regarding on-body police cameras. On-body recording systems [OBRS] would have been incredibly useful in Ferguson, he says.
