The 4th amendment says the people shall be secure in their persons, papers, home, and effects from unreasonable searches and seizures. If you are seen dumping your wife's body out of a boat out on a lake, there is not an unreasonable search and seizure. The Russians using x-rays and microwave radiation to spy on what goes on INSIDE and embassy is unreasonable. A dog being walked down the street that smells meth cooking is not unreasonable. Viva la revolucion.
