In my opinion the appropriate thing to do at this time is to offer condolences to the family of the man who was killed. He was a family man, Marine and corrections officer.
To speculate as to how this "ACCIDENT" occurred is irresponsible. According to all reports the investigation in incomplete, so why should the Captain (who has 25 years of experience in that port) be accused of causing the accident by failing to use his electronics properly, or by speeding?? By doing that you essentially accuse him of killing the man by acting recklessly, which as far as I know is a crime. He doesn't deserve that at this point, and I would hope that the facts will prove otherwise.
Lesson learned, be careful out there.
