From Ammoland:

The indictment alleges that, beginning in at least June 2018 through at least March 2021, the defendants conspired to acquire machineguns and/or other restricted firearms, such as short-barreled rifles, by falsely representing that the firearms would be used for demonstration to law enforcement agencies, including the Coats Police Department and the Ray Police Department. The indictment further alleges that Hall, Sawyer, and other conspirators signed law letters with no expectation that the weapons would ever be demonstrated to their respective law enforcement agencies.
