Smart cities mission is the next generation cities phenomena. The Makeover from an ordinary city to a smart city also demands the interaction of technological modules with political and institutional modules. Political modules represent various political elements, policy agendas and politics that may affect the outcomes of Information Technology initiatives. Institutional modules are always inclined to remove legal and regulatory barriers. This research paper is an attempt to shed some light on what type of contribution such technologies may offer as well as on how their potential may be turned into reality i.e. vision of smart cities. The research paper intentionally attempted to draw the plight of 9/11 terrorist attack; how an attack thrashed the international trade; its larger impacts not only within a country rather than across countries; how an attack pull the consideration on the issues of safety, security and privacy of human race worldwide. Finally, the researcher finds the solution in smart cities mission; it is a city where information technology is the principal infrastructure for achieving a high quality of life for all citizens, maintaining international trade promotion and protecting the natural environment. Then researcher draws the link how the legal assessment of related legislations is prerequisite for the success of smart cities vision. The best part of this research paper is smart cities needs smarter laws to make them smart knowledge habitat.
