Last week's CFP was focused on the "freedom to think, move, and travel." Sadly, it tended to highlight a decline in most of these since last year, as the government has increased surveillance without proving any increased security to justify these privacy invasions. Bruce Schneier kicked things off with a reminder that new security measures usually introduce new risks of their own, usually overlooked in their planning. Follow-on speakers noted that the political incentives often diverge from the stated security goals. I suppose we should be encouraged that so many people are thinking about the problem, but it's hard to come away optimistic about civil liberties right now. Dan Gillmor's warning about a perpetual state of war on terrorism catches the mood.
