The Supreme Court of the United States announced a decision in one case this morning:
Florida v. Jardines, No. 11-564: Police in Florida brought a drug-sniffing dog to Respondent Jardines’ front porch, where the dog gave a positive alert for narcotics. This led officers to obtain a search warrant, which revealed marijuana plants, and Jardines was charged with trafficking in cannabis. The trial court, however, suppressed the evidence, holding that the officers had engaged in a Fourth Amendment search without probable cause, and the Supreme Court of Florida agreed. Today, the Court affirmed, holding that the government’s use of trained police dogs to investigate the home and its immediate surroundings is a “search” within the meaning of the Fourth Amendment.
