Very possibly the cheesed off Joint Commissioner of Bombay Police is very right! To get some brownie points and some rewards some officers have let the things in the open. Terrorism has changed its face in India. Last year train bombers are not vagabond looking desperados but smart looking middle class educated ones who managed to get respectable accommodation in prime areas like Bandra etc. Even those who were caught did not break up easily with the police and police finally had to resort to truth serum test to make them speak; they are so well trained.
When terrorists are getting more sohisticated like this, would anyone expect to surface when all the TV channels beaming their sketches? They would have gone underground for a protracted time.
Perhaps that explains why the US did not get a second terror attack since 9/11 in 2001 and India having every now and then at the choice and time of even these small scale medium sophisticated terrorists.
