I think there's another issue here as well. Privacy and copyright are both largely fucked for the same reason. The grander the scale we communicate and understand things on, the more information will coalesce. The more a person will want to know something, the higher chance they will be able to find it without having to obtain the property rights. Its a fair assumption, that if a law enforcement agency at a high scale needs to know something, the information will be easily available. It's inevitable. In addition to requiring fair laws (as far as what the law enforcement agents are watching for) there should be a difference between what can be prosecuted based on this information, and what is an invasion. If you're seeking a terrorist, but you find a drug dealer, you should not be able to prosecute because the suspicion which led you to investigate was void and therefore an invasion. Should you still be able to confiscate the drugs? sure... But legally, there should be a conceptual barrier here.
