I go back and forth on the issue of whether violence to achieve social or political goals is a good idea. My current thinking is that, however justified it may be, political/social violence inevitably leaves everyone worse off than they were before. France wanted to be rid of the Ancien Regime; they overthrew it and were stuck with the Reign of Terror, Napoleon, and in the end just wound up with another king. Russia wanted to be rid of the Tsar; it got Lenin, Stalin, the gulags, and genocides instead. England wanted to be rid of the Stewarts; it got Cromwell. The American Revolution is one of the few I can think of that have been relatively successful, but even that was after tens of thousands dead, the new states bankrupt (with the attendant social turmoil, manifesting in a number of rebellions in the 1790s), political tensions that boiled over in another war with England, and before too long a central state which had become every bit as oppressive as England in an economic sense (resulting in the secession of the Southern states and the War of Northern Aggression).
I can't bring myself to say that violent resistance to Tyranny is wrong, but neither can I see it being productive and having a positive end result in the vast majority of circumstances. Someone(s) could fairly easily do some real acts of violence against The State, but in our modern age The State is so large and powerful that the efforts of a small group of people doing violence against it would have no real effect on its operations, but would almost certainly result in the perpetrators' capture and execution. IMHO, it takes a very particular and rare confluence of circumstances and events to make anti-state violence effective, successful, and beneficial. I don't see that happening in the US of A right now.
There have been a few instances in the last decade here in Southern California and around the country of people attempting to assassinate entire city councils after their lives have been ruined by code enforcement goons, zoning ordinances, crooked cops and the like. Sometimes they succeed in killing a government official or two (or three!), but the resistors always wind up dead and nothing ever changes. (they're also inevitably branded as 'terrorists' and the incident is always used to justify even greater oppression locally, with citizen activists often being dragged off to mental hospitals - exactly the way dissidents in the Soviet Union were often dealt with)
I think the only clearly moral way to resist State evil is by withdrawing from the system, as Sicarius already does. Starving Leviathan of its tax revenues by living an unproductive life (in a financial sense) and being for the most part untaxable is the only way to do any real damage to it with no ill consequences.
