I was at a local charity event and one of the local LEOs volunteers there with me. We were outside having a smoke and he started talking about this new group calling themselves "FreeLanders" (aka Soveriegn Citizens). 

He had just arrested his first, had met with lack of cooperation, and had handled the guy a little roughly.

They are mighty dangerous, you know

He described how they were dangerous

* don't believe they have to pay taxes,
* don't believe they have to register vehicles

to some of the roughest and meanest SOBs I know

* drive drunk
* pick fights
* drive unregistered vehicles
* work under the table

and they all nodded in horror. 

I kept my mouth shut.

Update:
Holy crap, it just occurred to me. All these rebels that think they can go stuff it to the law think its cool because they are flouting authority. People who peacefully resist, by simply not recognizing the authority, scare these guys (the rebels)... Are bad people as far as the rebels are concerned.
