Problem: A known drug dealer has a mansion surrounded by a 6-foot 8-inch fence for privacy. Detective McFadden is 6 feet 9 inches tall. On a hunch, he goes up to the fence and places a 100X power telescope and an infrared thermal imaging device and surveys and looks into the home for possible drug activity. He also has a finely tuned sense of smell and believes he can see and smell a light cloud of Ankara gold, a high grade, sweet smelling Turkish cannabis mixture. Detective McFadden has a 6-year background on the undercover narcotics squad. He arranges for search warrants of the house. Discuss the police conduct and its constitutionality.
