All interactions between law enforcement personnel (police officers, prison guards, soldiers, etc.) and the public should be mechanically recorded in some way such as through video and/or audio. These records should be kept for at least one year, but preferably indefinitely, and should be referred to when needed to help settle a dispute. One way law enforcement personnel could meet these requirements would be to wear small, unobtrusive audio and possibly video recording equipment as part of their uniforms. Such devices should not enable the wearer to turn them off. These devices should also be designed to record as many variables as practical, like direction from which sounds come, movements and orientation of the officer or person wearing the device, etc.
