What is so ironic is that time and time again when spies are caught they specifically make sure that they don't have address books neither on them or stored somewhere. So this is essentially nothing more than all the innocent people in the world. The only way I can see this technical solution producing results is if all the people in the world were cataloged and then the remaining ones were spied upon using field operatives.
