> It's also my firm belief that our legal system has been undermining these basic concepts for decades now. It benefits the federal government to make this all very vague, as if modern technology suddenly means you have no expectation of privacy anymore. They've also mixed in some of that wonderfully authoritarian "for purposes of national security".

Very well said. While the legal system's details are important for a few avenues of effecting change, they're often used to bog down conversions into "what is" territory rather than staying focused on "what ought". And "what ought", based on the ideals laid out in our country's founding documents, is very different from "what is" in the modern day.
