Look to South Africa as an example of why things are happening the way they are. Simply going out and arresting your predecessor is a risky political move.
You can see how South Africa destabilized and mass fighting began in the streets very shortly after that happened.
This is why the plan is the way it is. Remember that.
Sure... and this is why nothing will really change. Without a significant emotional event the sheep will stay asleep.
Or, to put it another way: until one side literally destroys the other, they will continue to think they are winning and never give up.
Keeping the 'war' going on a slow boil is part of the plan...
