WHEN Dr Kanwarjit Singh gave up his seat to an elderly lady on the M15 uptown bus in Manhattan, he was jostled and racially jeered by a man who for no reason commanded him to kneel and apologise. When Singh ignored him, he was shot in the chest. But after being discharged from hospital, Singh dismissed the traumatic incident as one that could happen anywhere, and continues to live and work in the city he still calls his own. Barely a month later, a lone woman jogger of South American origin was found brutally murdered in the early hours of the morning in Central Park, New York Citys green oasis.
