Interesting. What limitations on search warrants are you thinking of when you say that? What are some examples of things investigators wanted to search, or perhaps could search pursuant to a warrant, that were later found to be so beyond the pale that no warrant could authorize them?
Interesting. Why do you think the question is what is beyond the pale. Interesting. Or maybe "condescending" is the word. Math, physics, and realty have always limited search. Try executing a search warrant on a satellite. We don't require satellites to come down out of orbit for a search warrant. Similarly, turning math into contraband would be equally stupid.
Unlike this comment, mine was written in good faith. I thought you might have had an example of a set of circumstances in which a judicial search warrant was deemed, perhaps by some higher court, to have been unconstitutional owing to what it tried to search.
That's not the issue. The issue is whether the majesty of government trumps reality. In reality, math obscures secrets perfectly. The choice is whether to make that math illegal.
This isn't a unique case. Sovereign power is potent, but it isn't unlimited in theory or practice, and it isn't unchanging. Genetic modification, cheap aviation, robots, 3d printing, cryptocurrencies, etc. challenge sovereign power and related stakeholders. For good and ill.
It is doubtful that genetic engineering can be meaningfully regulated. That's probably got consequences greater that perfect secret-keeping. Governments will have to get over it.
The reason you don't hear about that as much is that authoritarians and control freaks don't obsess on it. Or don't know that maybe they should, because you can encode a lot of information in dna and smuggle it inside a tiny insect.
