Bаrthоlоmew resides in а hоuse with а large yard surrounded by a fence. The yard is immediately adjacent to the house. Parts of the yard are not visible from the street. The police suspect that Bartholomew is growing marijuana in the yard. In order to inspect the yard, the police use an aircraft to fly over the house and yard. The police do not have a warrant. Is the visual inspection by aircraft a “search” under the Fourth Amendment?
