If the victim/complainant/whatever was the one with the camera, you'd still get most if not more of the benefits of accountability. So how can we make that happen instead? Simple - have the police there in two distinct roles: 1) a cop; and 2) your own personal film crew. They'd film it and perhaps even hold it "in trust", but you'd own it. Such a system would empower citizens a lot and contribute almost nil to the scary mega-state. We're currently experiencing a shift to authoritarianism by the backdoor with NSA and friends, and in such times cheap and effective solutions such as this, which achieve the stated goal and no more, should be championed I think.
