Wow, I stay away for a couple of days and come back to find dksuddeth advocating the overthrow of the government. It's almost an answer to the tree falling in the woods question.
And highthief, the chances of any violent rebellion happening in my lifetime in the US are diminishingly small. There's currently no rallying point for any of the dissenters or any mass organization towards deposing anyone. The vast majority of Americans would never support the destruction of the Constitution (although they'd probably change their minds quickly at the end of a gun), and the armed forces are simply too strong for anyone to make a direct attack. Trying to overthrow the US government would not only be pointless suicide, it would leave a negative legacy for the cause.
I actually thought about posting on this topic on my way to work on this morning. After reading the USA Today article, I'm starting to come to the conclusion that the Bush administration is making a direct attack on the 4th Amendment with this and warrantless wiretaps that the New York Times first reported on. Senator Lehey thinks that there are other programs that have yet to come to light with similar affronts to the 4th. There's also the issue that the Justice Department shut down their investigation into the wiretaps because they couldn't get security clearance to access the information - for the record, that's one part of the Executive Branch denying access to another. The White House certainly has some difficult duties in keeping us free from foreign terrorism, but to me it almost feels like there are police/NSA spies around every lamppost and listening to every phone call. I keep waiting for the court cases to start flying, but I haven't seen anything major yet, although the latest report is certainly too new for anyone to have done anything about.
