shiv sena has never been named for any bomb attack...even they are never booked for a single murder never even in a political murder...only problem with them is they have extreme indian nationalism, with hindu nationalism, along with marathi nationalism...but they have done several losses to government & public property during strikes & even manhandled several media people(but some of them deserve it)...& some anti migrant,anti bangladeshi , anti pakistani anti australian , anti congress & anti bigboss rants...else everything is ok with them...
