U.S. Sup. Ct.
11-564
Police took a drug-sniffing dog to Jardines front porch, where the dog gave a positive alert for narcotics. Based on the alert, the officers obtained a warrant for a search, which revealed marijuana plants; Jardines was charged with trafficking in cannabis. The Supreme Court of Florida approved the trial courts decision to suppress the evidence, holding that the officers had engaged in a Fourth Amendment search unsupported by probable cause.
