If the feds want to spy on your home using whizzy tech gadgets, they'd better get a warrant first, the Supreme Court said on Monday. In an important 5-4 ruling that extends privacy's shield to radiation not visible to the human eye, the court said federal agents should have obtained a warrant before using an infrared imaging device to snoop on Danny Lee Kyllo, an Oregon man they later arrested for growing marijuana.

The decision, written by conservative Justice Antonin Scalia, said even though the law has long allowed police to peer at homes through their naked eyes, enhanced cameras and similar devices in law enforcement hands "would leave the homeowner at the mercy of advancing technology -- including imaging technology that could discern all human activity in the home."
