FILE- This undated file image displayed on a search warrant provided by the U.S. District Court for the Central District of California shows a very small piece of moon rock, center, taken from Joann Davis during a sting operation. A federal agent unnecessarily degraded Davis when he interrogated her for nearly two hours in 2011 after seizing the moon rock she said her late husband had received from astronaut Neil Armstrong, a federal appeals court said Thursday, April 13, 2017.
