Yes we can certainly do things..
Collectively we can spread the words through mass media or even create facebook page with testimonials...which will be shameful for the airport authorities..
Hopefully they will learn from it after that.
If there is anyone around here in SAJHA who knows how to spread the word around here in western world,,please do so,.,
And yeah as someone suggested above,,,if anyone find anyone else in the situation of getting harassed,,please help them fight the situation and not pay the bribe.

Together we can win against these crooks.
