It is not widely publicized but organized crime has a presence at most major airports in the USA! (not to mention around the world) The degree of illegal activity is much more wide spread in less developed countries. Ironically, these countries often have much more severe penalty for things like drug trafficking and smuggling. Even with straps around your zippered luggage, the "bad guys" can still open any zippered luggage and remove your valuables or put contraband inside. There are many stories about innocent people going to prison (and worse) for someone else's crime. Don't be a victim, buy hardsided, non-zippered luggage!
