6. The Dissenting Opinion ▪ It was an “off-the-wall” observation. ▪ There was no desire for privacy, as he did not attempt to hide the heat signatures. ▪ The observations were outside of the home, and could have been obtained by watching the snow melt off the roof. The Court Opinion ▪ Qualitly or quanity of information is irrelevant. ▪ The home is private, and privacy is expected, even if the heat was not hidden. ▪ The method in which the information was gathered was unacceptable, and did not give the police the justification to use improper means.
