A number of countries including my own introduced laws enabling them to prosecute their citizens for sexual offences against children committed abroad precisely because sexual tourism to countries where child prostitution is endemic and the local authorities either turn a blind eye to or are actively involved in the commercial sexual exploitation of children.

Perhaps Bruce was so dazzled by the limo service provided by the hotel (something which is pretty standard throughout SE Asia and not unusual elsewhere either) that he was blind to everything else around him in Pattaya when he visited.  Given how impressed he seems to be that food and alcohol will be provided on the "world cruise", I wonder what he'll fail to notice going on around him on that adventure.
