The Supreme Court Must Draw a Firm Line on Police Searches - NYTimes.com
Jared Sperli stashed this in life
If the police can’t thermal-scan your home from the street, why let them dog-scan it from your front porch? The government argues that a dog is alerted only by illegal contraband, while a thermal imager is set off more generally by “innocent” and “guilty” heat of all kinds coming from a home — whether from grow lights or from, as Justice Scalia noted in the thermal imager case, “the lady of the house” as she “takes her daily sauna and bath.”
But, arguably, this distinction is misplaced. If the court rules for the government in the home-sniff case, it is hard to see why the police could not station drug-sniffing dogs outside the entrances to every school, supermarket and movie theater as a routine form of drug interdiction. Dog sniffs would never involve a privacy intrusion and therefore would not trigger the requirement that the police obtain a warrant or have individual suspicion.
Moreover, today’s dogs will give way to tomorrow’s high-tech contraband-scanning devices that, under the reasoning pressed in the dog cases, would free the government to conduct routine scans of people’s homes or their bodies for all manner of contraband (or possibly for noncontraband, like marijuana grow lights, that are most commonly associated with illegality).
