What happens if the CIC (where the radar operators would sit), lookouts, and bridge team were all properly posted with trained watchstanders, who collectively dropped the ball?

Don't get me wrong, the CO is still "accountable" here, but while the buck may stop with him, there is going to be plenty of room for blame by the time this is all settled out. I don't care who the CO is, there's no excuse for a Navy watchteam on a modern destroyer to miss on oncoming container ship so badly.
