Revolution

Thinking about revolutions is dangerous. It almost invariably involves deposing a government, or somesuch, and governments decide upon laws. Therefore, revolutions are by definition illegal. This is my reason for investigating revolution as a crime, an act requiring means, motive and opportunity.

Means - what is needed to create a revolution?
Motive - why would we commit ourselves to a revolution, what would be the benefit, and for whom would that benefit be?
Opportunity - what forces in society help or hinder our revolution, thereby creating our opportunity?
