Heard about this last night on Coast to Coast AM:
Tax crusader Irwin Schiff found guilty on all counts
Irwin Schiff wrote a number of books over the years about paying zero income taxes. I've seen one or two of his books in bookstores. He claims that there is no actual law that makes him liable for income taxes and that the 16th Amendment was not intended to give Congress extra taxing powers.
Whether or not his claims are true, the Government wouldn't have let him get away with it. Imagine what would happen if he did go free. Millions of people will stop paying taxes, citing his case as precedent. The Treasury will become a tip jar. They might have to cut the mohair subsidy. :)
