The law trumps your opinion. https://www.npr.org/sections/alltechconsidered/2014/02/25/282523377/thermal-imaging-gets-more-common-but-the-courts-havent-caught-up https://www.npr.org/sections/alltechconsidered/2014/02/25/28... > In 2001, the Supreme Court held in Kyllo v. United States that police officers violated the Fourth Amendment when they used a thermal imaging device to detect marijuana plants growing inside a home. "Where ... the government uses a device that is not in general public use, to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a Fourth Amendment 'search' and is presumptively unreasonable without a warrant," wrote Justice Antonin Scalia. > To make his point, Scalia added that the device can tell you things that the average person would not be able to tell standing outside the house. "[F]or example, [the device can reveal] at what hour each night the lady of the house takes her daily sauna and bath," he wrote.
