When former IRS agents testify before Congress and the American people that they routinely ignore and break the law -- preparing dummy returns, seizing private property without due process and committing mail fraud with bootleg notices -- they are admitting the tax collection system in this country is a criminal enterprise, a violation of the RICO statutes at the very least. I would be perfectly delighted not to file a return (even though it only takes me about 30 minutes), but the public is dealing with an agency no different from the Cosa Nostra.
Yes, I do file a return every year; I just don't give the government anything it can use against me. 'Nuff said. ;)
