Off late, we can see quite a number of party members, are behaving in such manner. Be it these MIM MLA's or the Women wing of Shiv Sena. They know that they can do such a thing, get free publicity as this would appear in all channels as well as print media.
Politicians and Police will raise a finger against such behaviour. Just to show the public that justice is being done, these guys would be produced in court and let out on bail.
Judiciary should take a strong action once and for all. Put these guys behind bar for atleast 6 months. This will ensure that such behavior will not happen in future.
