The motormouth indiscretions of rent-a-quote politicians have a nasty habit of coming back to bite them. And showing up their ‘sagely’ pronouncements as the cynical mechanics of politics where anything goes. Which is why the Congress party’s topmost troll, Digvijaya Singh, is today performing linguistic contortions to deflect criticism of the failure of the party’s government in Assam to restore order for days after the riots broke out.
