Do u think movement like Tunisia and Egypt is necessary in India against Corruption and slow judicial system?

Public movement in Tunisia and Egypt has changed political system from dictatorship to Democracy and now people of Bahrain and Libia are struggling for Democracy. India is already a world's largest democracy but corruption and slowest judicial system is like a cancer in India. 2G Spectrum, CWG , Adarsh Housing society scams are few examples. Corruption of Govt. Employees are also known to us. Do u think we , Indians, also need revolution to fight agnst these evils? Why? Why not ? If u dont agree then how shld we fight agnst it?
