Cameron Watkins v. United States

Calling it a night, Petitioner Cameron Watkins closed the curtains of his motel room, partially undressed, and took to his bed. A police officer, looking for a different person who had committed a crime nearby, pressed himself against the window to peer through a one-inch gap in the curtains. He saw a handgun on the bed. As a result, Mr. Watkins was arrested, convicted of being a felon in possession of a firearm, and imprisoned. The question presented is: Whether the Fourth Amendment allows a police officer to unnaturally position himself to peer into an intentionally obscured private dwelling, simply because he is not trespassing when doing so.
