The two weekend blasts in the national capital in a fortnight's time seem to have shaken the denizens here as a sense of insecurity creeping in their minds with many of them expressing fear to go out for shopping in a market or for a family outing.Delhi Police Commissioner Y S Dadwal's assurance about stepping up security in the city also seems to have not provided relief to Delhiites, who say that a second blast took place in broad daylight and two bombers managed to escape from the scene, despite increased vigil by police."What are you talking about when you say security has been stepped after the serial blasts. Another blast took place within 15 days in broad daylight. Is Delhi secure? We are afraid," says Kumar Ranjan, a shopkeeper in Mehrauli.Recalling the tragic death of a teenaged boy in Mehrauli who picked up the bomb packet and tried to return it to the bike-borne bombers, Prakash Rawat, a lawyer, says that now onwards nobody will dare to take a packet from the roadside and try to return it."The fear is there. No one knows what is in store for you when you step out," he says, adding that it is not that terror strikes alone that create apprehensions in his mind."The total crime scene is changing in the city. You have the Bunty-like gangs and see the way the bikers planted the bomb yesterday.""I am afraid to go to markets these days," says Amrita Gupta, a college student.But psychologists say this fear is short lived and a natural reaction at a time of crisis. "This fear is short lived. The power of life is so strong that such fear cannot live forever. People will not stop going to markets or to their work places. It is an immediate reaction which is natural. Power of continuation is stronger than fear," noted psychologist Sameer Parikh said.
