The reason Lane didn’t argue AOM was because his only interest in the case was to get some of the prinicpals in the CIA and gov’t under oath in deposition and thereby dig out info on the assassination.
Lane really didn’t give a flip about Liberty Lobby.
He told Liberty Lobby, the only way I’ll represent you, is if you let me go at the merits.
And Lane wanted the trial which Oswald never got.
This was the closest he could get.
