The main culprits are Aboo Azmi and Amar singh. they have a great nuisance value. Mulayam singh is now aware of it and thats why he keeps amar singh at distance. Suppose there is a couple living very happily so many years and the very entry of amarsingh in that couple will start fighting between them. UP cm mayawati also had a rally in mumbai but there was no nuisance. Any average person can understand it but illiterate up biharis who are slave of their village leaders wont understand. they can be provoked easily. whaat raj told was bitter truth.
