Uk is just trying to find the scapegoat before they can start to big ones.
Well if they start with maoist , then it can be big issues so they started with the government forces  to whom they have provided financial and logistics support at that time
 , now this has kept the maoist mum, coz later when they tried on maoist, will do that later for sure, its just a matter of time., they will pinpoint see we have started with your enemy, they will say, we dont see you as ours neither they as ours, we believe in human rights and thats our duty, so we are trying you as well.
