There will of course be protests against such militias (eg:- Ranveer Sena or Salwa Judum or Village Defence Cadres), especially if they are not properly monitored and directed, but the alternative is a failure of security and prolonged civil war. Those who protest should be asked to consider the condition of the locals if they are not so organized and just left to the mercy of the insurgents. Also, you can’t tell the terrorist from the good locals, the local militiaman can. He can also discriminate between genuine and justified movement/travel and that which is not.
