That's a fair summary of what happened.
But it doesn't matter because LA chose not to contest ANYTHING. Not the findings. Not the peremptory judgement. Not the abuse of protest. Not the lousy evidence preparation. Not a thing. He just raised his hands in the sure and certain knowledge that this meant "OK I lose and you win."
Now why would an innocent man, with the resources and public profile of LA, and with everything that he stood, and still stands, to lose do that if he didn't dope?
Why he did it is irrelevant. It does nothing to excuse the process itself being unsound.
