Going forward, cops breaking the law will be an anachronism. Record keeping of human society will only perpetuate and render privacy obsolete.

You could grow the notion of comparmentalized information in such a society to create a kind of decentralized system of checks and balances. Eg you see footage with faces hidden and review the morals, vote etc

Could even crowd source such a thing. Surely, related AI efforts are in progress, for better or worse, e.g. FBIC (Facebook intelligence community) info gathering mechanisms

The law itself could eventually evolve to be more dynamic, decentralized
