Your "on demand" makes it read like they don't need to get a warrant whereas your link describes a missing-children investigation that had already made the national news, i.e., a situation in which getting a warrant would be very easy.
Well, sure, but more often than not, when someone on HN gives a URL to support some point, the URL ends up not actually supporting the point. I'm curious why people do that. Why did you do it?
