The Supreme Court has issued an opinion in Florida v. Harris.
JUSTICE KAGAN delivered the opinion of the Court.
In this case, we consider how a court should determine if the “alert” of a drug-detection dog during a traffic stop provides probable cause to search a vehicle. The Florida Supreme Court held that the State must in every casepresent an exhaustive set of records, including a log of the dog’s performance in the field, to establish the dog’s reliability. See 71 So. 3d 756, 775 (2011). We think that demand inconsistent with the “flexible, common-sense standard” of probable cause. Illinois v. Gates, 462 U. S. 213, 239 (1983).
The court sneezed when it came application of inflexible evidence standards for when a dog alert provides probable cause for a search, “A sniff is up to snuff when it meets that test.” Slip op. at 9.
