It does seem rather odd that Oswald would not have been stating something at the midnight conference or at any other point afterwards, about his presence standing on the front entrance when the shots were fired.
Captain Fritz being Captain Fritz, he may have been telling Mr Oswald, 'Calm down, son, we know you were out front for the motorcade. That's not why you're here. You're looking at a double charge of killing an officer and conspiracy to murder the President. Your rifle was used by the shooter, and we know you brought it into work this morning.'
We must bear in mind also that Mr Oswald was not aware that he was about to be murdered and so would never get a chance to tell his side of the story.
Thankfully, 55 years later, we now have his side of the story. And guess what? It makes a whole lot more sense than the official story!
