This is a PUBLICITY STUNT BASED ON LIES to promote Shah Rukh Khan's next movie "My name is Khan". Even if frisking or interrogation were performed on him, it should be of no surprise because there have been enough truly global icons who have been the victim of Homeland Security vigilance but they did not make a big hue and cry over them. For example, Cat Stevens (Yusuf Islam) of "Katmandu" song fame was denied entry into the US probably because of his Islam conversion. Another one, Amy Winehouse, six grammy nominee was denied visa to the US because of her drug addiction but still performed live on TV in real time amidst five grammy wins. Our very own cinema icon Rajesh Hamal was denied US visa.
This episode proves that,  people of India like most South Asian countries, do not hesitate to claim of being victims based on lies, under-employed people support the victim with protest demonstrations, and Government officials retort with sharp remarks without proper analysis. If Indians are so angry at their so called "global icon" waiting at the airport for his baggage, why doesn't he start traveling in private jets?
The 911 hijackers were of middle-eastern descent. Obviously, anyone resembling them would be more likely to be subjected to more thorough screening. If you got nothing on you, why should you be worried? The officers are just doing their jobs.
