I’m happy to bash the IRS, but I usually try to explain that our anger should be focused on the politicians who created the corrupt, 74,000-page tax code.

But sometimes the IRS deserves some negative attention. The tax collection bureaucracy has thieving employees, incompetent employees, thuggish employees, brainless employees, and victimizing employees.

The senior folks at the IRS also deserve scorn for bone-headed decisions such as squandering millions of dollars on a P.R. campaign and a scheme to regulate and control private tax preparers.

Now it seems we have another reason to condemn the tax-collection bureaucracy. The IRS is engaging in Nixon-type political harassment.

Here’s some of what the Associated Press just reported.

The Internal Revenue Service inappropriately flagged conservative political groups for additional reviews during the 2012 election to see if they were violating their tax-exempt status, a top IRS official said Friday. Organizations were singled out because they included the words “tea party” or “patriot” in their applications for tax-exempt status, said Lois Lerner, who heads the IRS division that oversees tax-exempt groups.
