This poster tells a lot about Thailand.
In most other countries the sign would simply read: "Beware of pickpocketing" or "Beware of pickpocket gangs." In Thailand, it's "Beware of Non-Thai Pickpocket Gangs," because, clearly, Thai people would never engage in such demeaning activities as pickpocketing!
Tourists need to know that, so that–in case they get robed in Thailand–they can still tell their families and friends what a paradise on earth Thailand is. And once their friends decide to go on holidays to Thailand to experience the paradise for themselves, they could tell them: "Oh, you're going to have a blast, just beware of non-Thai pickpocket gangs!"
