I'm thinking that most of the folks who are capable of such still hold faith in the social contract we all live under.
My fear is "What happens when those folks feel the contract is broken?"
The simple answer is people stop upholding their end. In little ways at first. I imagine Tax evasion will become more of a middle class thing. Some folks who thought the NFA was crap will just build whatever they want. Same with drug use. In some places "Shoot, Shovel, Shut-Up" will become a community approved way of dealing with criminals.
Eventually it will become as dangerous for Law Enforcement as they'd like you to think it is now. Why would I allow enforcement of a law on me if the rule of law is not consistent? Why Should I? Think of the stories of Revenue Agents disappearing in the hills of Moonshine country.
Then folks in Randy Weaver esque situations will start asking themselves "Why wait until the FBI comes up here and shoots my family". Something on the KillDozer-Tim McVeigh spectrum will hold appeal.
Look at the TDS dude that's been hiding in the woods for 3 months. Now imagine him hunting the 12 agents hunting him.
