Shiv sena U-turn MNIK booking haulted in Mumbai

My Name is Khan (starring Shahrukh and Kajol )is supposed to be the most graceful International release ever. But the controversy with SRK's comments on Mumbai Shiv Sena doing a U-turn and backing off from their words, advance bookings in multiplexes in Mumbai of MNIK has been halted . It is also reported that over 1200 Shiv senas were arrested during their protest against MNIK. Does they have a little of blue blood in them ?
