Freedom, how long will it last?

We recently saw an effort like this in Iran when the Iranian citizens used Twitter to broadcast the real story of the post-election protests despite a media blackout enforced by the government of Iran. If Americans are stripped of the ability to use technology to communicate, our government might very well have the ability to stifle speech just as the Iranian government did. While we are all concerned about national security, we must not stand by while our elected officials use scare tactics to trample our rights and take away our fundamental freedoms.
