Two contrasting images of Mumbai earlier this week strongly evoked for me a city stratified and compartmentalised in its grief, despite the terrible assault on its people, its buildings, its very soul. One was of a candlelight march on Marine Drive last Sunday, the day after the siege of the Taj had ended. The candles flickered in the balmy evening breeze, placards bobbed up and down among them, some of the slogans on them reflecting all the rage that has been spilling out of TV screens these past few days. While the purveyors of roasted channa-seeng did great business, and candle-less families sat on parapets and lifted their faces to the breeze, quietly savouring their city’s return to freedom and mobility, the internet-enabled and the SMS-connected talked about how "we can’t just sit and watch", how we must "act", and how if enough citizens come together they can "start something". There were not all young and idealistic, by the way, some were middle-aged and very angry. Like Mukul, who wouldn’t give his surname. "These 500 people we have elected need to be taken out," he said, waving his "No Security, No Taxes" placard. (Yes, he did use that Bush-esque phrase "taken out") "We need people who can change things." When another journalist and I prodded him to spell out his vision for change, he said: "I am a businessman. I know how to do my job, let them do theirs. I can’t lift a gun, I can’t terrorise people."
