INSURGENCY is big business in the North-east. Its an industry with a turnover of over Rs 600 crore per annum. The rebels levy annual taxes on big business houses and traders, and collect monthly taxes from government servants, offi-cials, doctors and engineers. "Insurgency ended 20 years ago," says former Meghalaya chief minister B.B. Lyngdoh. "There are only extortionists and robbers now in the garb of insurgents." With the police nowhere in the picture, its all as official as it can get. On pay day, representatives of the rebel groups station themselves in government offi-ces and deduct the tax (between 1 and 10 per cent of the basic salary) at source.
