Those who want you to doubt that anarchy (self ownership and individual responsibility) is the best, most moral, and ethical way to live among others are asking you to accept that theft, aggression, superstition, and slavery are perhaps better.
If you see a Reaver ("law enforcement officer") or have to be around some government facility or employee, it is wisest to simply assume you are doing something "illegal" or at least something they won't like (and will probably use as justification for further scrutiny or molestation).
This isn't being "paranoid"; it's being smart. It is the reality of the police state in which we find ourselves living today. Don't deny it or fight it. Accept it and survive.
