I'm not certain if he's looking for my legal expertise on the particular issue, but if someone is a trespasser on your property, it doesn't necessarily mean that you're assuming responsibility for that person while they're there. In some jurisdictions, such as the United States, depending on the state, that does indeed happen, and that is my understanding. But certainly you would not suggest that someone who owns a ship is going to be responsible for stowaways and for somebody carrying on an illegal activity. I suggest that would be beyond public policy, and it would certainly be beyond this government's purview.
