One problem with infringements on civil liberties is that they tend to build on each other over time through precedents. Once liberties are restricted in one context, it's not that hard to justify restricting them in another. So we have to be careful. I agree that the PATRIOT Act has not produced the effects many of its more outspoken opponents said it would, but I think it is, in many ways, our duty to resist such infringements, and always force politicians to justify them. So while I understand the necessity of restricting civil liberties, I also think that our existence as a democratic society means that we should subject all attempts to restrict them to very harsh scrutiny. What I am saying is that, in a very abstract way, our civil liberties should always be as expansive as is possible and practical at any given time.
