"A sniff is up to snuff when it meets that test."

Defendants split today in the USSC: seizures away from the home not allowed as a means to hold people while their residences are searched (6-3, B/A/T dissenting), but (in a crisp unanimous opinion by Kagan) a search/seizure on the street via dog sniff upheld, the state court required too strict of a test for competency. Other sniff case not decided.
