Is the way shown in "A Wednesday" movie the right way?

Is the way shown in "A Wednesday" movie good? Does the situation really demand such way? The facts that really support this way are –
1. Afjhal Guru, the main culprit of the Parliament attack is still in Jail. Because of political matters, his capital punishment (Death penalty) decision is still pending.
2. Mumbai Blasts case was solved after 15 years.
3. Gujarat riot case is still not solved.
4. Kashmir issue related to Terrorism and related to Security at Border is still as it is.
5. Seven sister issue is still not solved. Instead it is getting worse. May be after some years it will not be a part of India.
6. A Naxalites issue is still not taken as a serious issue.
7. Number of blasts is increasing day by day.
8. People are taking this way for getting publicity. Same case happened in Rajasthan for getting the reservation.
9. SEZ issues are also going that way. People are opting for violent ways in which armed mob will decide about the issue.
10. Amarnath issue was also one of them. It was a simple decision between Amarnath Shrine board and Government. But it took a totally wrong turn and destroyed the valley business till one and half month.
What can be done to avoid this? How can we do something to avoid such things?
