FOR the villagers of Nabingaon, a tiny hamlet in Assam's Nalbari district bordering Bhutan, the discovery of six bodies on the morning of August 18 came as a rude shock. All the six killed were Bodos. In a state where violence is a part of the daily grind, the deaths would have been counted as another piece of statistic but for the fact that the attack came from the most unexpected quarter—Bengali Hindus. Irked with the successive attacks on them over the past fortnight, the Bengalis living under Tamulpur police station area in Nalbari district decided that offence is the best defence. Taking the lead in this revenge is a nascent armed outfit which calls itself the Bengali Tiger Force (BTF).
