In the recent decision in Florida v. Jardines, the United States Supreme Court considered whether police could lawfully use a drug sniffing dog to search a the curtilage of a person’s home.
In a unanimous decision, the United States Supreme Court held that law enforcement must apply for and obtain a search warrant before they can enter the private property of a person for the purposes of gathering evidence of a crime.
In this particular case, after receiving a tip, the police conducted surveillance of the defendant’s home. Officers eventually approached the house with a drug-sniffing canine dog, who sniffed the defendant’s porch area and front door. After the canine signaled positive for drugs, the police used that information and applied for a search warrant and eventually arrested the defendant for drug trafficking.
