Hartals

I don't hear DS ever reporting any leader on the ground (whether AL, BNP, Jamaat, JP or otherwise) calling for calm during protests, never is it mentioned that an MP stood before the mob behind her/him and prevented violence. It takes great leadership to truly believe in a cause and take it through, our 'leaders' lack both the faith in their cause or the courage to see it through; there are those who have marched on our streets before us who were able to maintain the dignity of the protest, of the hartal, they have struggled and have won. Today, we have bus loads of people brought into the city, paid to wreak havoc and chaos over petty, pathetic, criminal political squabbles which have little to do with our lives.
Calling hartal is a democratic right, but compelling others to observe it by picketing cannot be, as it is against the basic principles of democracy. So is there anyone who can file a writ petition to the court for a ban on picketing on hartal days ?
