Criticising authorities over handling of commuter rage and breakdown of suburban train services last week, the Shiv Sena today mocked the Centre's promise of "achche din" and asked where are the good days assured to the people.

"It is true that there were protests (on Friday) and they had turned violent. But neither the police nor the authorities are willing to probe what led the people to turn violent," an editorial in Sena mouthpiece 'Saamana' said.

"If similar incidents, that had taken place during the Congress rule, continue abated, who exactly is experiencing 'achche din' (days of good governance)?" it sought to know. "Those (political parties) who thought that law should be taken into one's own hands when they were not in power, have their government now. If these protests were a result of people's frustration towards administration, we need to ensure it doesn't become a cause of law and order breakdown," the Sena, which is part pf the ruling BJP-led alliance at the Centre and Maharashtra, said.
