I completely agree with you and how Billy is wrong with his claim. Since the FTC has obtained proof by aerial photography, there is no violation of the constitution because no warrant is required for observation by the public. All the proof they obtained by aerial photography is valid and can be used against Billy. A subpoena to testify or to produce records cannot be opposed because it is a search and seizure. A significant difference between an agency hearing and a court hearing is that there is no right of trial by jury before an agency. Therefore, Billy has no right to a jury trial.
