India, Sept. 30 -- W hat recently happened to a 17-year-old girl in Aastha Kunj has inflicted another wound on Delhi's conscience. The girl had gone to the public park to celebrate her birthday and was gang-raped by three men disguised as policemen. Some are questioning 'Why did she go in the evening?' But, shouldn't the question instead be: Why can't a girl walk freely in a place created specifically for people to breathe in the open air? The solution is not to lock up parks or ask women to stay indoors. Across the world, a concept called CPTED is used in urban design: Crime Prevention Through Environmental Design. At New York's Central Park or London's Hyde Park, they don't imprison parks behind towering walls. Instead, they focus on 'natural surveillance'. Boundary walls are kept low, or replaced with see-through chain-link fences. Emergency SOS blue-light boxes are installed every few steps. And what about us? We build eight-foot-high stone walls around our parks. Inside, it's dark. From the outside, they become complete blind spots. Public spaces belong to everyone. Safety is a human right, not a privilege!...
