There's some important stuff over at the Electronic Frontier Foundation in response the U.S. Department of Justice's proposed "Anti-Terrorism Act" (ATA) which I encourage you to check out.
We fully support legitimate government efforts to bring the perpetrators of these attacks to justice. Yet as a watchdog for civil liberties, we are skeptical of claims that the only way we can increase our security is by giving up our freedoms…none of the legislative changes that have been proposed so far is temporary — these are broad ranging, permanent reductions in civil liberties and privacy of all Americans. History has shown that such laws, passed in haste during a time of crisis, linger and cause difficulties long after the crisis has passed.
