Plenty of crimes happen at sea. Cruise companies expend effort to sweep these crimes under the carpet: https://www.youtube.com/watch?v=0nCT8h8gO1g
Criminals are people who've been convicted of a crime. These people are either:
- allowed on cruises (I'm not aware of a "no conviction" clause when buying a cruise ticket)
- in jail, in which case you can also make the argument they're not allowed out in public
So criminals are allowed on board, and people who might commit a crime are not necessarily criminals yet.
