Could you cite a link to the case you're thinking of, where evidence from SIGINT surveillance was used directly as probable cause for a search?
Also, could you yourself update your mental model of what's happening on HN? You obviously think I'm a tenacious foe of civil liberties causes. The opposite is true. I've done as much in the real world to support civil liberties causes as most anyone else on HN has. I contribute to candidates who I believe support a strong fourth amendment. I've canvassed for candidates like them. I donate to civil liberties causes.
What I have a problem with are batshit conspiracy theories, which is something HN is rife with. People should stop pretending that conspiracy theories are helpful when they're of the right valence. They aren't.
If you've actually followed me around HN, you know that I'm not at all unwilling to acknowledge when I'm wrong, as a cursory look at HNSearch will show. So, instead of yelling at me, why not show where I'm wrong?
