Kevin Williamson of National Review Online believes impeachment is not enough for embattled IRS commissioner John Koskinen.

He shouldn’t be impeached. He should be imprisoned.

When the feds couldn’t make ordinary criminal charges stick to the organized-crime syndicate that turned 1920s Chicago into a free-fire zone, they went after the boss, Al Capone, on tax charges. Under Barack Obama, the weaponized IRS has been transformed into a crime syndicate far worse than anything dreamt of by pinstriped Model-T gangsters — because Al Capone and Meyer Lansky did not have the full force of the federal government behind them.

If you do not know the story — in which case, shame on you — a brief recap: After years of pressure from Democratic grandees including Senator Sheldon Whitehouse and Senator Chuck Schumer, the IRS began targeting conservative nonprofit groups for various kinds of illegal harassment. Applications for nonprofit status were wrongfully delayed and denied, while investigations into those organizations’ tax statuses were turned into partisan fishing expeditions in order to expedite harassment against donors, volunteers, and political activists. This involved organizations that are under the law explicitly permitted to engage in political activity. Democratic officials at the state level joined in and continue to do so, with California attorney general Kamala Harris demanding donor lists from California-based nonprofits that came into her crosshairs — with no legal justification.

This is a flat-out illegal campaign of criminal harassment and intimidation of political activists involving the criminal misuse of federal resources for illegal partisan political ends.
