They have data from over 8,500 blasts. Sadly, more pours in daily.

A worrying trend in the last two years is the use of locally procured ingredients. From Delhi's Sarojini Nagar market blasts to the Mumbai train explosions, there has been a growth of explosives made out of innocuous items such as fertiliser and plaster of paris. "It is a myth that RDX is the preferred choice of terrorists. Now they use material that could be bought over the counter and then put together." And how far are we from identifying the actual bomb-makers? "For that we will still have to fall back on good, solid intelligence," a senior intelligence official told Outlook, "but the more methodical we get, the chances of fingerprinting the bomb-maker improves substantially."
With the intensity of attacks going up, the NBDC is under pressure to upgrade its facilities. It has a fairly decent forensic laboratory but hasn't found a suitable scientist to run it. It does have a huge electronic database but the need for a wide area network is imperative. "Ideally we would like to have representatives in every district so that we get authentic data," says a senior NSG official. Such minor glitches continue to dog the NBDC's efforts. While it posts a 23-column "feedback" form for state agencies, it has not been able to augment its communication channels. For an organisation of its importance, it has a phone that is difficult to get through and an e-mail that does not work. This prevents the flow of information between different departments when a coordinated effort is the need of the hour.
But, despite these hiccups, the NBDC is learning and growing fast. It has been successful in recreating most of the major blasts in the country, adding valuable data that helps connect critical dots in an investigation. "Our latest challenge is the blasts in the Samjhauta Express. It had a printed circuit board and a timer-delay device that could be switched on or switched off by turning the lock key," says a senior NBDC official. This helps investigators understand the sophistication of the terrorists, their external linkages, if any, as well minute details such as the fact that the terrorists, in this particular case wanted to cause death by burning rather than through the blast.
While analysis is a constant activity at the NBDC, every new blast brings in fresh data. The latest blast at the Mecca masjid in Hyderabad is now on the radar. As analysts discuss possibilities with Andhra police, they are veering around to a few basic facts. "The bomb was ingenious but not very reliable. Cell phone signals can get jammed or you could fail to make the call. But a pattern will definitely emerge," a post-blast investigator told Outlook. And so, investigators are waiting for what the next blast will bring. At one level it's a depressing wait, but for them it could mean the difference between life and death.
