What gets me is the stupidity of coordinating this by email. All it took was perfectly legal requests by citizens for the emails to uncover the whole rat's nest.
Doesn't surprise me a bit. People are generally ignorant about how very permanent an email trail can be.
If you have any experience with electronic forensics or discovery, you quickly learn that people will say anything in email, and be absolutely confident that they've covered their own tracks by deleting it. After it's been sent, forwarded, archived, etc. etc. etc.
