Tram Lady Emma West has reached the end of her ordeal. In a negotiated settlement she pleaded guilty and was given a minimal sentence "bound over to keep the peace", and a mental health treatment order.
There is a good write-up here.
Of course she was outrageously persecuted by the authorities who never dared actually try her - she was persuaded to plead guilty eventually.
Will we see any of the blacks who have mouthed off on public transport in the same way in court? Probably not.
