If you look at the UK as a prime example, all hope of legally destroying the tyranny has been lost thanks to the various terrorism related laws that have been introduced. The same is true of the US as well now thanks to the ability to detain people on suspicion indefinitely. The legal system is beyond repair.
Revolution has been destroyed too as the very act of promoting or discussing it is terrorism under law and people will just be locked up before they have a chance to express or organise. Our modern communication infrastructure supports this outcome.
The best thing we now hope for is to survive in quiet obedience or await for a natural disaster to shift the balance.
