Clearly, it is a dangerous thing to have well-meaning, but under-educated people swear an Oath to "protect and defend" the Constitution of the US and Utah, when they very likely have never read them, let alone understood them. Through our ordeal we have come in contact with, or been affected by, somewhere near 200 government employed "oath-takers". The only thing that We, the Cromar family, has ever needed is ONE "oath keeper" to recognize that we NEVER had a Hearing, let alone a Trial by Jury to face our deceitful lying IRS accusers, and step in between Us and those dangerous, heartless, and often mindless powers of government which have all but ruined our lives, honor, stolen our home and its contents, endangered Us, destroyed our ability to make a living.
Clearly, they don't understand how the system works.
When the IRS audits you and issues a statement of deficiency (I forget the exact term), it is not a criminal proceeding, it is purely civil. You are not entitled to a trial, let alone a jury in such a proceeding. It is an entirely administrative process. If you don't like the outcome, you can either not pay the additional tax and file a case in the Tax Court, or you can pay the tax and then sue in Federal Court to recover the money. In both of those cases, you will then be entitled to due process in court. Perhaps not a jury trial, but at least it will be a court, rather than an IRS conference room. At that point, you can argue the law. With the IRS, you can not really argue a point of law, just the calculations and the categorization of income/deductions.
If the IRS finds that you have engaged in criminal tax evasion, they may bring criminal charges against you. In that case, you will DEFINITELY be afforded a jury trial.
Basically, they haven't progressed to the point of getting a jury trial. Yet.
