Privately Run Cities

Honduras is paving the way for three privately run cities. They will each supposedly have their own police, laws, government and tax systems. It is being done in an effort to promote wealth creation in the area through trade, something like the things that have been done in Dubai.  I am a bit skeptical of this actually happening but it will interesting to see even if only one is accomplished. The question, though, is wouldn't warlords take over?
