I wonder how much of our concept of "privacy" is the residue of doctrine and precedent regarding the procurement of search warrants. Whatever is off-limits to the search gets tagged as representing some personal quality, sanctified as intrinsic to the person, and placed in a
basket called "privacy." It can then serve to regulate, more or less haphazardly subsequent discussions of rights as they appear against the encroachments of new telemetrics. A lot of "psychology" and discussion of the "human" has no doubt been formed similarly.
@truepeers We'd need a history of search warrants but I assume they itemize what the constable is searching for, or as the 4th amendment to the US Constitution has it, "particularly describing the place to be searched, and the persons or things to be seized."
@truepeers I think it will depend on whether you find the child porn where you were already permitted to search for the drugs. There is also the "plain sight" rule, though.
