I. Does a police officer violate the Fourth Amendment by opening a
digital file and viewing an image in it without a warrant to confirm a
private company's statement that the image is child pornography
based solely on the company's comparison of the hash value of the
image and the hash value in a digital database said to contain known
child pornography when there is no evidence that the database
actually contains images of child pornography, how the images in it
were selected, or who selected them?

II. Does a police officer go beyond a private company's search, which
merely compared the hash value of a digital file to hash values in a
digital database said to contain known child pornography, by opening
the file and viewing an image in it without a warrant to confirm that
the image is child pornography?

III. Has this Court's holding in United States v. Jacobsen, 466 U.S. 109,
123-25 (1984) — that it was not a search for the government to field
test white powder revealed to private employees when a package was
damaged — been abrogated by the property rights analysis of the
Fourth Amendment in United States v. Jones, 565 U.S. 400 (2012)?
See United States v. Ackerman, 831 F.3d 1292, 1307 (10th Cir. 2016)
(per Gorsuch, J.).
