You really are totally clueless, aren't you?
The IRS, in conjuction with the DOJ (the IRS can't indict anyone, they refer criminal cases to the DOJ for prosecution after they have conducted their investigation) routinely takes years to get around to bringing criminal charges.
Take a look at recently convicted tax protesters/tax cheats Schiff, Rose, Meredith and Thompson. All of those cases dragged on for far more than one lousy year beyond the point where the IRS got interested in their activities.
You seem to think that your boy can do no wrong because he hasn't yet been criminally indicted and/or civilly enjoined. Believe it or not, it can take longer than a year or two to bring a scammer to justice.
I won't wait for your apology when you're finally disabused of your odd notion.
I don't claim that he has "done no wrong." I personally do not know if he has or has not as far as that case is concerned.
I do know for a fact that the last time the IRS tried to harrass him, they ended up returning the cars they seized.
And if the IRS had anything to charge him with, they would of done so already.
