US Copyright law is a federal law about how copyrights are protected, but the posted regulation is about what federal work is copyrighted and NOT applicable to how state work is copyrighted. It even says it right there in the title: “Copyright_status_of_works_by_the_federal_government_of_the_United_States.” The jail photographer is not an employee of the federal government, nor is the trial an activity of the federal government. This photo was not a work by the federal government.
