Probably arrested, held in jail optionally in solitary and eventually charged with large crimes of violating a national security letter. I'm not sure but considering other recent events probably leaking top secret government info. Followed by jail time and possibly financial ruin. Don't fuck with the US gov. They are publically making it very clear.

This guy didn't break the law, just "offended" the gov and his life "is over" in that he has a 7 year jail sentence and financial ruin to look forward to when he gets out.
Bradly Manning offended the gov and broke the law, and is facing over a lifetime in jail after some torture like jail conditions pretrial (and nearly faced execution).
Blogging a NSL would probably get you somewhere in between.
