FWIW I had an FAA inspector on my flight from CUN to FLL last November. He does repair station inspections or some such. He told me to be extremely careful in cancun that it was not safe at all. He further claimed that as a result of a drug bust at the airport that ended with a lot of drugs confiscated from an airplane the drug cartels had kidnapped and beheaded the airport manager and his replacement is now being guarded by a platoon of Mexican army soldiers.
