Just to let you all know, Income Tax is used to pay "The Fed" interest on the money they print. We, the United States as it is written in the constitution, have the right to print money w/o being taxed on it, Abe Lincoln (with his greenbacks) and JFK both tried (both where shot in the head too!).
I can't remember the exact verbage in the constitution but it says something about not being taxed on the money recieved from primary sources of income. I'll find that snip-it soon.
Those two reasons are basically why income tax is unconsitutional.
P.S. I didn't think Micheal Moore put that video out, I thought it was some other producer.
