Maybe yer thinkin' of this artical in tha ucmj:
Article 88—Contempt toward officials
“Any commissioned officer who uses contemptuous words against the President, the Vice President, Congress, the Secretary of Defense, the Secretary of a military department, the Secretary of Transportation, or the Governor or legislature of any State, Territory, Commonwealth, or possession in which he is on duty or present shall be punished as a court-martial may direct.”

There was not a single contemptuous or disrespectful word on that banner. Not one!
