The constitution nor bill of rights apply anymore to anyone in FL. The feds do not need any probable cause, no warrant, nothing. They can take you out of your bed and make you disappear permanently. State and local different story. That being said the SCOTUS has already said the constitution and bill of rights apply to NOBODY in FL if the feds are involved ..you know "national security".
If they can get away with this illegal sniff search from your front doorstep, they'll be going door to door spraying front door knobs with a substance that turns red when it contacts resin residues. This stuff is already on the market and being used in public schools.
Curtilage in United States law
This distinction is important in United States law for cases dealing with burglary and with self-defense under the "Castle Doctrine." In some state law, such as Florida, burglary encompasses the English common law definition and adds (among other things) curtilage to the protected area of the dwelling into which intrusion is prohibited. Similarly, under Florida's Castle Doctrine a home-owner does not have to retreat within the curtilage.
The boundary between the home and the curtilage that surrounds it, on the one hand, and the open fields beyond the curtilage, on the other, is also important for the application of the prohibition against unreasonable searches and seizures under the Fourth Amendment to the United States Constitution. The warrant requirement of the Fourth Amendment applies only to the "home," which courts have construed to include the area immediately surrounding the house in which the intimate home activities occur, but not to the open fields beyond. The requirement that law enforcement officers obtain a warrant before searching a suspect's home extends, therefore, to the curtilage, but not to private property beyond the curtilage, even if their access to such "open fields" without the owner's permission would constitute a trespass.

In United States v. Dunn, the Supreme Court identified four factors as critical when assessing the limits of curtilage: "the proximity of the area claimed to be curtilage to the home, whether the area is included within an enclosure surrounding the home, the nature of the uses to which the area is put, and the steps taken by the resident to protect the area from observation by people passing by."
