If a leader or society is corrupt, and uses this power to persecute its civilians. Then this form of oppression must be toppled. And the only way to accomplis this is to have a revolution. I believe that a corrupt society can only be changed by revolution. In a corrupt society, that corruption usually comes from higher powers such as the leader of the society. These people control everything; your salary, job, taxes and the military and police. In these cases the government can cover up any situation. They can kill who they want and get away with it. The police forces, who are controlled by the government, control what information the public receives. So most of the time we aren't getting the whole story, just what we are told to believe.
The only way to rid ourselves from this corruption, is by a revolution. If everyone stands their ground and says "we aren't going to take it anymore", if every person stops working, paying all taxes and decide to defend their homes and communities, the government will be forced to give in to our demands. The way to shut down the government is not to blow up building but to cut them off financially. If the corrupt leaders lack funds then they will not be able to pay their police officers. If the state is without people to uphold the law then they are at the mercy of the angry populous. Then they must give in. Blowing up buildings is not the solution. That only causes a backlash from the police. Its is like fighting a tank with your bare hands.
A good example is the Spanish War. The Anarchists fought the Fascist and ended up over throwing them. The country had full working anarchism. They had no government. This worked for a while until the Fascists re-gained power and killed everyone. This just shows that the only way to overthrow a corrupt government is by revolution. The anarchist had a revolution and won. Life was good until the fascists attacked and then all was lost.

The only way that a corrupt society and government can be overthrown is by direct confrontation and a revolution by the people.
