Hitting out at Jayalalithaa government for foisting "false land-grabbing cases" against his partymen, DMK chief M Karunanidhi said on Saturday that they are not afraid of jail and the Dravidian movement cannot be wiped out by such 'vendetta politics'. "I do not know how long I will live but am sure that nobody can finish off DMK and the feeling of being a Dravidian will not diminish," the 87-year old leader told a public meeting in his home constituency-cum-native town.
