"The U.S. Supreme Court has said that having a drug-detecting dog sniff luggage at an airport or a car during a traffic stop does not amount to a "search" under the Fourth Amendment and therefore does not require a warrant. A case that Florida's attorney general has asked the Court to consider raises the question of whether the same conclusion applies to the use of a drug-sniffing dog outside a home. Miami-Dade police brought the dog to Joelis Jardines' house on December 5, ".........
I believe the appropriate question would be, "is the home located on private property?" Did LEO have authority to be on the property for due cause?
This of course, is a blanket question, and not necessarily applied to the above case. My point is that, absent "good faith" can LEO arbitrarily bring a "drug sniffing" certified dog on any personal property to "sniff" for drugs?
Considering nearly all paper currency in the world has residual evidence of drugs, particularly the snorting types, I think a good attorney could shove most drug sniffing dog cases up the LEOs and prosecutors wazoo, if just cause isn't present.
