Step-by-step explanation:
The court's decision in the Kyllo v. United States case was that the use of thermal imaging technology by the police without a warrant to detect the heat patterns in a person's home constituted a violation of the Fourth Amendment's protection against unreasonable searches and seizures. The Court held that the use of the technology was an invasion of privacy and constituted an unlawful search. Therefore, any evidence obtained through the use of the thermal imaging technology was considered inadmissible in court.
