Non-Violence is the best "Mantra"

This is reference to the recent Naxal attacks, Hijack & Hostage drama.
What is really Naxals are achieving by doing this kind violence? Are they able to show down their faces? Are they able to roam freely like other people?
Whatever the issues are, All the issues need to resolved by dialogue. So far in the history or at present, nobody win with help of the violence. I can understand that tribal s are tortured, arrested by police and Government is totally ignored them etc. But the naxal cannot achieve anything by taking arms in their hands.
Clearly, i can blame the politicians. They taking the support of the people at the time election and after that nobody is working out the people's grievances. People also equally to blame. How many citizens knows about the vote? or Significance about the vote? Many people so thrilled by voting for money, after that they blaming the Government.
I believed that the Gandhian way of non-violence is the best way. Though it takes so much time to get the result, but the result will be fruitful.
