Police suspect that Sam Samella is growing marijuana in a remote field on his farm. Samella has a barbed-wire fence posted around the entire 50-acre farm, pit bulls patrolling the fence perimeter, and “No Trespassing—And I Mean It” signs every five feet.

Police suspect that Noah has been conducting illegal genetic engineering experiments in his basement in an effort to develop a horse with a horn growing out of its forehead. They don’t have enough evidence to obtain a search warrant. They go to Noah’s place, which consists of two acres of land. On the land is a house enclosed by a fence at a distance of 50 feet from the house. A barn sits outside the fence. The police trespass on Noah’s property and look in the windows of the barn. They see two of the one-horned horses. At Noah’s trial, he objects to the evidence observed by the police through the barn window as an illegal search. Is he correct?
