I do not understand how citizens can benefit by the government installing cameras and face recognition software? Can you explain in more detail what do you mean? I hope you do not suggest citizens install also cameras and put the videos on the web, then we have private companies and citizens tracking us not only the government. And I assume when a minister receives a bribe he will not be meeting with the person in a public place.
