When local body elections are held in Tamil Nadu later this month, it would bring back horrid memories to the Dalits of Melvalavu village in Madurai district. Twenty three years ago they had elected one of their ilk to the post of panchayat president, defying a diktat of the upper caste Thevars not to enter the electoral fray. A few days later, on June 30, 1997, a mob of Thevars hacked to death the newly-elected president and six more Dalits in a brutal reprisal.
