I wanted to make a similar point but tried to do it so as to avoid giving any offense.
Why object to my trying to be polite?
I don't think there is a law against walking down the street with a purple lampshade on your head.
But why would anyone bother to ask if there was unless he was considering the possibility of it happening.
All I tried to do was talk thro some of the possibilities.
Further, I did point out the bit about safe havens which indicates there might be law which at least implies the right (legally) to enter a port or harbour.
If its so important then perhaps best you consult a lawyer who can give a definitive answer
