What is the current state of the law in the context of the Fourth Amendment?

"The Fourth Amendment provides in relevant part that the 'right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.' The Amendment establishes a simple baseline, one that for much of our history formed the exclusive basis for its protections: When 'the Government obtains information by physically intruding' on persons, houses, papers, or effects, 'a "search" within the original meaning of the Fourth Amendment' has 'undoubtedly occurred.' " (Florida v. Jardines (2013) 569 U.S. 1, 5.) "[W]hen it comes to the Fourth Amendment, the home is first among equals. At the Amendment's 'very core' stands 'the right of a man to retreat into his own home and there be free from unreasonable governmental intrusion.' " (Id. at p. 6.)
