Again, corrupt officials, selective enforcement, etc are the problems, not lack privacy. There are a number of ways to make the nature of law better (free markets for law, direct democracy, actual representative democracy, etc), which would all render the need for as much privacy as people are advocating moot.

The minute you declare privacy enforcement a greater problem than fair law-making and fair law enforcement, you've started a losing game for which the oppressors (the ones you're using privacy as a defense against) have already won.
