From The Hindu:

Half of India-Bangladesh border fenced

Shiv Sahay Singh KOLKATA, MARCH 03, 2017 00:48 IST

Half of the 4,096-km border India shares with Bangladesh has been fenced. Land acquisition is a major challenge to completing the work by the 2019 deadline.

… The aim of the project is to curb infiltration and smuggling of cattle and fake Indian currency notes….

Another important issue in West Bengal is that a large part of the border is riverine: rivers running along the border serve as the border. For instance, 70 km of the south Bengal frontier — from South 24 Parganas to Malda — is riverine. “Where fence is not possible, we are going in for technological solutions such as cameras and lasers,” Mr. Singh said.

All Prime Minister Modi is asking for is sharks in the river with cameras and laser beams on their heads. Is that too much to ask?
