What I would do...

is compile a complete record of all emails and phone calls via hardwired access to all communications. Then I'd create a dossier for each person on the planet. Then I'd collect "metadata" from the communication service providers that link each person's identity to their respective communication content. Then I'd sit back and wait for anyone to step out of line. When anyone does, I'd access his or her dossier and have my team of analysts pore though it to find the kind of dirt that helps me convince him or her to step back in line.
