Political benefits kisko nahi chahiye ?
Mamata Bannerje do this in Bengal , Congress did this during Bhandarkars movie..
At the end there will be deal between Bhansali and bjp.. both will get benefitted by this. Bhansali will remain in controversy hence free promotion and bjp will get it's particular vote share. Karni Sena will be used as a puppet only after election is done. Who cares for this karni Sena ? Neither BJP nor Congress..
For your information Congress state leader also made statement in the favour of movie ban. Both bjp and congress will use this for their benefit.
Politics is not that simple thing whether one is good or other is bad. It's all about benefit.
