United States v. Romm
United States Court of Appeals for the Ninth Circuit
455 F.3d 990 (2006)
Stuart Romm (defendant), while in sole possession of his laptop, located child pornography online, kept liked images on his screen for several minutes before deleting them, and manipulated some smaller images to view them more easily; the images were automatically stored in his internet cache, giving him the ability to print or send them, and he admitted knowing this and described his own conduct as "saving" and "downloading" the images. Romm was convicted of receiving and possessing child pornography and appealed, arguing merely viewing the images didn't rise to the level of receipt or possession.
Whether the mere ability to manipulate an electronic image on a personal laptop is sufficient to establish possession of the image.
