AC 360 Keeping Them Honest - Cruise Ship SafetyAnderson Cooper’s show AC 360 "Keeping Them Honest" aired a special program last night "Who’s Keeping Cruise Passengers Safe?"

The program follows a string of cruise ship mishaps dating back to the Costa Concordia disaster last year up to the fire aboard the Royal Caribbean Grandeur of the Seas last week. 

Where are cruise lines incorporated? Where do cruise lines register their cruise ships? Is there any international authority with legal authority to enforce safety regulations?

CNN interviewed me and Senator Rockefeller who has convened safety hearings into the cruise industry.

The Cruise Line International Association (CLIA) and Royal Caribbean declined to be interviewed.
