> Or it doesn't even have to go that far; some government spokesperson lets your name slip in an interview as a "suspect" and the media attention you'll get will forever ruin your life even if the government does nothing.

Unless the government gets out of the business of handling birth certificates, driver's licenses, etc. they're simply going to have your name.

Secure communications channels is certainly an important topic though, but given what happened to Sunil Tripathi in the aftermath of the Reddit swarm to find the Boston Marathom bomber(s), perhaps it's possible that your biggest "online threat" in the future won't be part of the government at all.

You get the wrong Google, Facebook, or random datacenter sysadmin upset and you could find yourself in hot water with even less of a legal recourse. It's just as easy to imagine roving bands of vigilantes in that dystopian future as it is to imagine Big Brother, is it not?

I get why this (COMSEC) is an important problem; what I don't get is why so many otherwise very intelligent persons focus on the government as the sole problem area. The government is mostly staffed by either those who are actually idealistic, or those who are too incompetent to hack it in the private sector. Certainly Google and Facebook have better IT infrastructure than 99% of the government.

P.S. The U.S. Constitution forbids "ex post facto" laws that make previously legal behavior illegal after-the-fact. If you believe that the Constitution actually means anything you shouldn't worry about currently legal things being held against you in 20 years. If you believe the Constitution won't hold up in 20 years then it's kind of pointless to worry about any of the other laws, they'd be just as shredded.
