An anonymous reader writes: Stanford's Ryan Calo has previously told us that 'that there is very little in American privacy law that would prohibit drone surveillance within our borders.' But will UAVs not only be legally permitted to monitor us in public, but also be used to 'peer' into homes with high-tech thermal and chemical sensors and alert police to the presence of illicit substances or other suspicious activity? Calo writes in Wired about a pending Supreme Court case, Florida v. Jardines, which will determine 'whether the police need a warrant before a dog can sniff your house' like they already do to luggage at airports. According to Calo, if the Court approves of these searches, it's a small leap to extend that same logic to the use of drones, allowing them 'to roam a neighborhood in search of invisible infractions such as indoor marijuana.' He concludes: 'The wrong decision in Jardines makes this and similar surveillance scenarios uncomfortably plausible.'
