From an Oct. 31 editorial in the Los Angeles Times:
The Supreme Court has said that at the very core of the 4th Amendment stands the right of a man to retreat into his own home and there be free from unreasonable governmental intrusion. The courts commitment to the sanctity of the home will be tested by a case featuring as familiar a symbol of domestic life as the family home itself a dog.
The justices will decide whether police committed an unreasonable search when, acting on an anonymous tip, they deployed a drug-sniffing Labrador retriever named Franky at the Miami-area home of Joelis Jardines. The dog sniffed around outside the front door and gave the police the signal they were looking for, on the basis of which they obtained a warrant, and a search discovered marijuana. Jardines was charged with trafficking in more than 25 pounds of marijuana.
However, the Florida Supreme Court ruled that even though neither the police nor the dog entered the house without a warrant, the search was illegal. While this case is not identical to (or, as lawyers say, on all fours with) its previous decisions safeguarding the privacy of the home, the U.S. Supreme Court should follow suit.
Since 1967, the court has recognized that an unconstitutional search need not involve physical trespass. In a 2001 decision that is likely to loom large in Wednesdays oral arguments, the court ruled that federal agents violated the 4th Amendment when they trained a thermal imaging device at a home to determine if the building was generating the sort of heat associated with marijuana production.
Writing for the court in 2001, Justice Antonin Scalia observed that the heat-sensing machine was an example of advancing technology of a kind that potentially could discern all human activity in the home. By contrast, drug-sniffing dogs are low tech and trained to detect only illegal activity.
But it shouldnt matter whether privacy is breached by a machine or canine, and the fact that illegal activity may be going on inside the home doesnt negate the need for probable cause.
Finally, Florida argues that no search occurred because even when Franky tracked odors to their strongest point at the base of Jardines front door, he was breathing only the air outside the house. The court rejected a similar distinction in the thermal imaging case.
What mattered was that the device in that case, like the dog in this one, was detecting what was going on inside the house. Without a warrant or probable cause, that amounts to an unreasonable search.
The court should say so.
