Is that what you're trying to argue about?
Maybe Kyle should have thought of what might happen before he named Ventura as "Scruff Face" on the Opie & Andy show.
Apart from the logical flaw in inferring that only Ventura’s witnesses would lie for him and not Kyle’s, consider the testimony of Bill and Charlene DeWitt, two witnesses who were at the bar the night of the “fight”:
Bill DeWitt has known Ventura since the two underwent Basic Underwater Demolition/SEAL training together in 1969. . . . The DeWitts, Ventura and other BUD/S classmates . . . convened at McP’s bar the night before the ceremony — the same night Kyle and his colleagues were at the bar for the wake of slain SEAL Michael Monsoor. . . . ”I was eavesdropping on Jesse,” [Charlene DeWitt] said. She heard him criticize the war in Iraq but didn’t hear him badmouth fallen soldiers or argue with younger servicemen. She said she didn’t see him get into a fistfight or sport a black eye or bruised face in the following days. . . . Bill DeWitt also testified that he hadn’t seen or heard any of the events described in the book.
