Atrocity of Shiv Sena

I am very much suprised to see the activities of shiv sena. It is continously posing problems in mumbai. If a political party is acting irresponsibly like this what is the need of parties in India?
There are many problems that India is facing like poverty,education,terroism etc..
Government cannot concentrate on that . If this party is giving problems like anti-muslims, against bihari's, etc.. the whole time of government goes in this way. I am asking shivsena "where were they during the terroist attacks & floods? " If they really care about marathis then they should join their hands with government and do some good to people. Don't disturb people like this. Better don't disturb people. Government should take firm action against this party. So that they don't do politics by testing people emotions.
