Thanks for posting that resource, John. I started watching the documentary Cam linked to and it generated many questions. All of the court cases featured in the documentary in which the income tax-avoiding defendants were victorious were jury cases. One in particular found for the defendant because the judge could or would not provide them with a law (or laws) giving the I.R.S. authority to compel the defendant to pay or face consequences. It certainly gives the tax protesters ammunition even if they are in the wrong.
