At some point, any freedom achieved may not be worth the freedom given up. This approach is sometimes called value-loaded futurology. It has to compete for scarce economic resources like any other agency. It's only a short step to closing down police departments for low crime rate months, much as cities layoff their lifeguards in non-summer months. The problem is one of what becomes the standard, as we are presently still in an experimental mode.
Law enforcement computerized systems also have the potential of trammeling all over our freedoms.
Educational and training uses for computers will probably become commonplace. Police services may become absorbed by this aged population. Also, whites will very shortly be a minority ethnic group, at least in size, and the death of white male privilege, when it comes, in our society, probably won't be pretty. The motives are endless. There might be such as thing as too much attention to policing.
