Stop thinking and analyzing, stop using common sense and this movie is a joy ride. and that is all.
Script is like written by someone with zero knowledge of Indian Penal Codes and their application in several occasions in this movie.
Story has nothing to do with reality, very poorly written script.
Story would have ended in the first five minutes as an International flight is returned to Delhi IGI. in Reality Farhan would have been locked up and there would have been roits on the streets as a Muslim stopped the flight.
Wake-up people are we this dumb?
