Strengthening economic security by plugging holes in existing mechanisms to track money transfer between India and other countries and legitimate banking channels — holes that terrorists seem to be slipping through — is top of the agenda as the country’s top cops begin a three-day meet here tomorrow.

Threat to vital infrastructure and transport will also figure at the national conference of Directors General and Inspectors General of Police. The Home Ministry is believed to have suggested that “security cost” should be included in the project cost in key infrastructure projects for effective protection against extremists. This argument, according to officials, is valid not only for states like Jammu and Kashmir and the Northeast but also for states where Naxalites have threatened to target projects.

The Maharashtra police have proposed a task force for a railway security plan that can be implemented uniformly throughout the country and should include necessary legal changes and a passenger-screening system on the lines of that drawn up for Mumbai after the serial train blasts.

Officials said that use of economic intelligence for national security was emerging as a key strategy to tackle threats. A detailed presentation prepared for the conference deals with this, stressing on the “failure of existing mechanisms” to tap international money transfer.
