The court said that police in Florence, Ore., searched illegally when, without a search warrant, they trained a thermal sensing device on a man's home to see if heat was radiating. Police found hot spots in the roof and one wall, used that to get a warrant, searched the house, found 100 marijuana plants growing under high-intensity lights and arrested the resident. Writing for a 5 to 4 majority that scrambled the court's usual ideological blocs, Justice Antonin Scalia said technology could not be allowed to erode "that degree of privacy against government that existed when the Fourth Amendment was adopted." That's powerful reasoning. Unchecked, technological developments in remote sensing could nibble away at the zone of privacy Americans enjoy until no place is safe from official snooping. The court was right to impose the same probable cause requirements on police conducting electronic searches as it requires of those who kick down doors. In dissent, Justice John Paul Stevens argued there is "a distinction of constitutional magnitude" between "through-the-wall surveillance" which would be an unacceptable search inside a home and "off-the-wall surveillance," as in this case, where police merely gathered information exposed to the public outside a house. Florence police had argued that in detecting heat loss, their thermal imagers did not reveal any private information. But as Scalia said, "all details are intimate details," inside a private home. He left for another day the question of how much technological intrusion is acceptable when the target is not a residence. But in its ongoing struggle to apply the Constitution's prohibition against unreasonable search and seizure at a time when technology is extending the eyes and ears of law enforcement to a degree unimagined by the Constitution's framers, the court Monday laid down an important marker. - --- MAP posted-by: Terry Liittschwager
