I think there might be different definitions of "enforcement in good faith" here. Your perspective, if I understand it correctly, is "The purpose of this law was presented as fighting terrorism and now it's being used for other purposes, which constitutes bad faith enforcement".

Another perspective is, "Law enforcement isn't doing anything that it shouldn't be doing, therefore they aren't acting in bad faith". Whether they're going after terrorists or drug dealers or money launderers, it's all the same to many (if not most) people. As long as there's no evidence that government officials are abusing the provisions of the PATRIOT Act to settle personal scores or persecute those with unpopular beleifs, most people will see them as acting in good faith. This assumes that actions taken are within a reasonable interpretation of the letter of the law, of course.

I get where you're coming from, or at least I think I do. I just don't think that the issue is so black and white. This may be a case of "The current government isn't doing what I want it to do" as opposed to "We should change the way that the laws are written". And the solution to that is pretty simple: Vote.
