Ever been on a cruise?

I went on an Alaskan Cruise with my mom and Grandma through Holland America a couple of years ago. Very pretty, but if I were to do it again, I’d probably want to do a Caribbean or Mediterranean Cruise and be sunny and swimming. However, one thing I never worried about while on board was this. WTF? Should we be worrying about international law enforcement on these cruise lines? Scary!!!!
