Imagine that the police force had robots that took pictures through your windows and then employed sophisticated object recognition and semantic inference engines to determine what is happening inside, matching it agains a database of known crimes. Then explain to me how that's different from the police officer who looks through your window to establish probable cause for a "search warrant". If your society is principled enough to require warrants to execute "searches", then it should be principled enough to recognize that this principle, by default, excludes any activity which has no measurable impact on society from criminalization. The first piece of evidence in any investigation should come without a search.
