For everyone suggesting that the offenders be put off the ship at the next port, is this even feasible? Would the cruise line have to notify the host country of their intent to disembark these unruly passengers (some of whom might be in conflict with others also being disembarked)? Does the host country have to accept these passengers? Would they even want to?
I'm not questioning the effectiveness of doing this, but I wonder how realistic this solution really is.
