The legal system is subverted by the national security apparatus by necessity and by design. The information gathered by ISPs is necessary to prevent interference with ground-based radars around airports, and is necessary for fraud detection and internal security of the network. It would be feasible to make it so that this information would be gathered and retained only for a short period of time to establish and maintain network integrity, such as handshakes and other bits and bytes exchanged and retained inherent to the protocols used. The legal doctrines that establish the legality of full take surveillance have been argued before FISA courts, so an act of Congress or a test case would likely be necessary to prompt any legal reexamination of the relevant issues. However, national security issues are not really able to be resolved legislatively, because executive orders will always enable that which cannot be done on the books, which presupposes that which is done is done by the book to begin with.

What is done in the shadows must stay obscured due to means and methods, and this ideology isn’t amenable to change, political or otherwise. There is not much else to say on that point as it is observational and experiential based on my lived experience and history of interactions with law enforcement, national security professionals, and private security as a service provider and former licensed security guard, as well as being a victim of police overreach and charge stacking. I’ve worked with law enforcement and been work for law enforcement. I’ve fought the law to a draw, and I’ve fought the law and lost due to bad calls by refs. I’m working on becoming a better citizen and community member so that I can be a helper. More than that, I can’t say. The future is hopeful and yet the challenges are real, and changing. Old guards are giving way to young Turks. It’s an interesting time to be alive.

The beamforming and other technologies used with modern WiFi are what enable the motion detection “for free” because the WiFi signals act as radar signals, the contours of the perturbations of which are already baked into the WiFi protocol. It’s insecure by design against this side channel attack.

You would have to reimplement the standards to make everything that squawks rotate their identifiers regularly, ideally after every transmission. It’s possible I suppose. I don’t think the political will is there to mandate this, and there are not that many people who work on these kinds of problems. Look at who created TOR. You’d have to run that kind of system everywhere, and only use it for everything, and that system would have to be part of the protocol or otherwise unable to be disabled by end users. Otherwise, you’re at the status quo we have now, where the weak links are the first to break.

If this sounds like a stretch, the weak links are always people, not protocols or pipes. That’s why this is magical thinking. As principled as you and I are, bad guys don’t have principles. Those who fight bad guys have principles, and they also have more coffee and mathematicians and hashrate.

Congress will never rule against the national security apparatus because there is no political will to do so. I can count on one hand the folks in Congress who are on relevant committees to even consider legislation on these matters who is in any way critical at all, and they largely agree with you that something needs to be done. But they don’t have the votes to do anything because the issues aren’t relevant to voters. No one cares the way you or I do, or they would probably become lawyers or politicians, as well as soldiers and broadcasters.

If you think something constructive and positive needs to be done, I would likely agree that the impetus for change exists. I’m all ears.
