Augusta Water Cooler makes the case for police wearing cameras - and eyes some drawbacks.
The storage requirements for footage recorded during most if not all contact with citizens by every officer on the the force could be staggering and complicated. This storage would also have to be managed so that recovery was practical and convenient. Another concern is the time officers would need to spend in order to upload their camera's footage and how that could effect their patrol activities and possible overtime issues. Policy and procedures must be adopted by agencies who use this technology so that usage is uniform and not arbitrary, plus officer training on use.
Think before jumping on the bandwagon.
