What if there is a law out there, a Federal felony that carries up to five years in Federal prison and a $250,000 fine, that you do not know you are violating?  

What if this law is so esoteric that when you are arrested your top notch $500 per hour Federal criminal attorney has to look it up because he has never heard of it?

What if said law was modified by Marshal Law (the "Patriot" act) to allow Civil Asset Forfeiture to apply in your case.

What if said law is one of the handful of Federal felonies that has no requirement of intent on the part of the defendant?  In other words not intending to break said law is not a defense.

What if you and your family are investigated by Homeland Security for 18 months, whatever "evidence" they collect, concoct, or flat out lie about is taken to a grand jury?  Said testimony is forever sealed so that neither you or your attorney ever get to see it (unless you go to trial) - thus allowing them to concoct or flat out lie with impunity?

As an example what if one of the lead investigators/experts that testifies states that it is his belief that "there are little or no legitimate uses for Bitcoins", hypothetically of course.

What is said secret sealed indictment is then used to generate a secret sealed search warrant for your home and business?

What if the Feds then execute said secret sealed search warrant and take all of your cash, bitcoins, computers, all of your personal financial records and all of your corporate financial records and anything else they can get their hands on?  Now, all of the stuff they take is assumed to be guilty of a crime and it is up to you to hire an attorney to prove that your stuff is innocent of any crimes - or they get to keep it all?

No, I guess you are right, you have nothing to worry about since you have read and fully understand all Federal, State and local laws.  Good for you.
