Given the factual events, it would certainly appear that the Captain is guilty of negligence and showboating at the least. There is also a suggestion of lying about the true state of damage that the ship suffered, possibly contributing to the delay in abandoning ship, and given the perception that the Captain of the ship should remain until the bitter end, the fact that he was in a lifeboat and again was somewhat evasive about that doesn't say much for his character. When this is all proven in court, they should throw the book at him, assuming all these facts are borne out.
I am surprised at the release of the audio tape and transcripts of the conversation between the coastguard and the captain though - the Captain is now being tried, scapegoated, in the court of public opinion. This is something the ship owners would probably like, since there are questions to be asked over their corporate policies.
The last time there was such public condemnation of an individual that I remember was the furore over joanna yates' landlord, chris jefferies, and in the end he was found innocent, but not before the media had performed a thorough character assassination on him.
This media frenzy over apportioning all the blame on captain schettino feels a bit like that...........
