With Respect:
Those looking for admissions of responsibility may wish to take into account that the captain may have been advised, or decided himself, that such an admission would be inadvisable in case future action, legal or otherwise, might be affected by it being brought up.
I remember very well in the UK having minor traffic accidents (and I am not necessarily equating the two, only the attitude) and being told "Don't say anything, don't say sorry, don't sympathise with the other party."
After any event where there may be repercussions one would be wise to keep one's mouth firmly shut and that is notwithstanding some places now have "I'm sorry" laws.
