Does what happens on a cruise ship stay on the cruise ship?

That’s the question some people — including a U.S. senator — are asking cruise lines. It shouldn’t be that way, say some industry watchdogs about what they call questionable reporting of crimes that occur on the open ocean.

The problem, some say, is a law that requires only certain crimes and investigations to be reported to the public. People like Kendall Carver, chairman of the International Cruise Victims Association, say that leaves the actual number of crimes aboard ships mostly unknown.
